--- type: Software Buyer's Guide title: 6 Best Accounts Receivable Software for MSPs in 2026 description: Paidnice, Chaser, Alternative Payments, Invoiced, FlexPoint and ConnectBooster compared for MSPs in 2026, ranked on whether the tool can hold a different late fee policy per client group and on what survives a PSA migration. resource: https://accounting.events/reviews/best-accounts-receivable-software-msps/ tags: [best accounts receivable software for msps, msp accounts receivable, msp ar automation, msp collections software, msp billing software, msp late fees, psa agnostic ar software] timestamp: 2026-08-27 --- **The six best accounts receivable software tools for MSPs in 2026 are Paidnice, Alternative Payments, FlexPoint, ConnectBooster, Chaser and Invoiced, ranked on whether the tool charges a late fee itself, how it connects to your PSA and what it publishes as a price. Prices from US$69 a month.** Paidnice suits an MSP on QuickBooks Online or Xero that wants late fees applied per customer group across any PSA. Alternative Payments suits a US or Canadian MSP that wants payments, payables and a human collections escalation from one vendor. FlexPoint suits an MSP whose largest AR cost is card and ACH fees. ConnectBooster suits a ConnectWise or Kaseya shop. Chaser brings multi-channel chasing on UK turnover pricing, and Invoiced sits at the mid-market billing end. **Related guides:** [the pillar guide to AR software](/reviews/best-accounts-receivable-software/), [the best payment gateway for MSPs](/reviews/best-payment-gateway-for-msps/), [the best AR software for QuickBooks Online](/reviews/best-accounts-receivable-software-quickbooks/) On Xero Small Business Insights data for June 2026, a US small business waits 29.1 days to be paid and settles 8.3 days past due, with the wait 1.6 days longer than the 27.5 days recorded a year earlier. For an MSP those days repeat every month against the same clients, so a nine-day drift on a monthly agreement compounds into a permanent hole in working capital. Where the client sits matters too: 38.7 days in New York against 24.1 in California. ## Chasing a client you also support An MSP bills the same clients every month under a managed services agreement, and the person who has to send the second reminder often took their call at 2am. That single fact changes what good receivables software looks like here. In a product business an overdue invoice is a cash problem, and the relationship usually survives whatever you do about it. Under an MSA the same invoice is attached to a contract that renews, a service desk answering to the same client, and an account manager who is mid-negotiation on next year's seat count. Nothing you do to the invoice stays inside finance. Four questions follow from that, and none of them appears on a feature comparison. Who does the reminder come from: accounts@, the account manager, or a platform the client does not recognize. Does the service desk know the account is 60 days out before it commits to another project. Is suspension available at all, and does your MSA actually say what you think it says. And what does a 1.5% charge look like on a client you intend to keep for five years. The second constraint is the stack. MSPs change PSA more often than they change ledger, and a receivables tool bound to a PSA connector has to be bought again when they do. That makes durability a purchase criterion here in a way it is not anywhere else in this category, and it is the subject of a section of its own below. The money-in half of the same problem, what card and ACH actually cost per dollar collected, is a separate shortlist with a separate ranking, and it sits on the [payment gateway guide for MSPs](/reviews/best-payment-gateway-for-msps/). What an MSP should be looking for: - **Reminders a client reads as normal.** Multi-channel follow-ups sent from your own authenticated domain, and where it matters from a named person rather than from a system. - **A charge the tool raises itself.** A late fee or interest computed and posted to the ledger, rather than inherited from a QuickBooks setting somebody left switched off in 2023. - **Policy per client group.** A flagship client on a three-year MSA and a month-to-month break-fix account cannot share one rule and both be handled correctly. - **A ledger connection as well as a PSA connection.** The invoice reaches QuickBooks Online or Xero whichever PSA produced it, and that path survives a migration. - **Something the service desk can see.** AR status that reaches the people actually talking to the client, so nobody promises a project start to an account that is 90 days out. The reminder an MSP sends is read by somebody who also has your lead engineer's mobile number. That is why the grain of the rule matters here more than the volume it can process. ## What we weighted for a recurring-revenue biller Recurring contracted revenue changes the weighting. Enforcement grain sits above price, because the same invoices go to the same clients every month, and a rule that cannot tell those clients apart gets switched off inside a quarter. 1. **Fit for a recurring-revenue biller.** Does the tool serve an MSP billing the same clients monthly under an agreement, at a price a small or mid-sized shop can sign off? 2. **Enforcement grain.** Does the tool compute a late fee or interest itself, and can the rule differ between a flagship MSA client and a break-fix account? 3. **Durability across a PSA change.** Does the integration survive a migration, or is it rebought with the new PSA? 4. **An entry price in public**, published or verified, in the vendor's own currency and dated to the month it was read. 5. **A rating with its base attached**, platform and review count both printed, and where two scores sit inside 0.1 of each other the deeper verified base wins the higher place. Where a capability could not be scored across all six it is printed inside the entry that carries it rather than used to order the list. Invoiced's price, its rating and its late-fee mechanic could none of them be verified from public materials, so none of the three moved its position. ## Six tools for MSP receivables Two rows carry most of the decision. Late fee grain says whether the clause already in your agreement can be applied per client. PSA integrations says what you will be rebuying the next time you change PSA. | | [Paidnice logo](#paidnice) | [Chaser logo](#chaser) | [Alternative Payments](#alternative-payments) | [Invoiced](#invoiced) | [FlexPoint](#flexpoint) | [ConnectBooster](#connectbooster) | | Revenue fit | $500k to $20m | £4m and under on the entry tier, tiers to £200m | To $50k a month of processing on the entry tier, $100k on the second | Not published | To $50k a month of processing on the entry tier, unlimited on the top tier | Not published | | From (monthly) | US$69 | £199 | US$199 | Not verified | Not published | Not published | | PSA integrations | No (reads from the ledger) | No (reads from the ledger) | ConnectWise, Autotask, HaloPSA, SuperOps | None found | ConnectWise, Autotask, HaloPSA, SuperOps | ConnectWise, Autotask, Kaseya BMS | | Ledger integrations | QuickBooks Online, Xero | Xero, QuickBooks, Sage 50, Sage 200, Sage Intacct, NetSuite, Dynamics 365, AccountsIQ, SAP | QuickBooks Online and Desktop, Xero, Sage Intacct, NetSuite, Dynamics 365, Zoho Books, FreshBooks | NetSuite, Sage Intacct, Dynamics 365 Business Central, Xero, QuickBooks | QuickBooks Online and Desktop, Xero; Sage Intacct, NetSuite and Dynamics 365 Business Central above the entry tier | QuickBooks Desktop and Online, Xero, Sage Intacct, Dynamics GP | | Late fee grain | Yes (per customer group) | Yes (one global rule) | None found | Not verified | No (from your ledger only) | None found | | Statements | Yes (any schedule) | Yes (monthly, fixed day) | Not verified | Not verified | Yes | Yes | | Payment plans | Yes | Yes | Yes (customer-paid financing, 30 to 150 days) | Not verified | Yes (financing, terms not published) | None found | | Takes payment | Yes (Stripe and Pinch Payments) | Yes (Chaser Pay on Stripe rails) | Yes (own rails, US ACH free to the payer) | Not verified | Yes (ACH from $1.00, cards at Interchange+) | Yes (BNG gateway plus a separate merchant processor) | | Rated (source, count) | 5.0 (82, Xero App Store) | 4.98 (374, Xero App Store) | 4.7 (11, G2) | Not verified | 4.9 (5, G2) | 4.2 (23, G2) | | Last verified | Aug 2026 | Aug 2026 | Aug 2026 | Aug 2026 | Aug 2026 | Aug 2026 | "Not verified" means the claim could not be confirmed from anything the vendor publishes.

Paidnice Best for MSPs on QuickBooks Online or Xero that want enforcement across any PSA ### What is it best for? For an MSP that wants late fees and interest applied automatically to overdue managed-services invoices, without wiring anything into ConnectWise or Autotask. **Fits:** MSPs billing through QuickBooks Online or Xero from about $500k revenue, with the sweet spot between $1m and $20m, with or without a dedicated finance hire **Regions:** United States, Canada, United Kingdom, Australia, New Zealand, South Africa **Entry cost:** Essentials at US$69/mo covers 150 invoices, 600 emails and 2 team members. Pro at US$99/mo and above lifts the seat cap entirely, with no per-seat fee, which matters where the account manager and the service desk both want visibility. Verified Aug 2026 **Rated:** 82 [Xero App Store](https://apps.xero.com/app/paidnice) reviews averaging 5.0 at the 20 August 2026 check, and 4.9 on [Capterra](https://www.capterra.com/p/254868/Paidnice/) with the count unpublished. Neither base is MSP-specific **Awards:** New Zealand Small Business App of the Year at the Xero Global App Awards 2026, following Global Small Business App of the Year in 2025 **Runs on:** QuickBooks Online, Xero, Stripe, Pinch Payments, CloudDepot, HubSpot, Pipedrive, Zapier. NetSuite, Sage Intacct, MYOB and Dynamics 365 Business Central on the Custom plan only **Late fees and interest:** Yes. Flat fees, percentage fees and compounding interest, with policies sitting under customer groups so different groups run different rules at once, and the charge raised on the QuickBooks or Xero ledger as Draft or Approved **Does best:** Holding one fee policy for flagship MSA clients and a harder one for month-to-month accounts at the same time, with both an invoice late fee and a statement interest charge posted to the QuickBooks Online or Xero ledger Paidnice has no PSA connector, and for an MSP that is the point. Your PSA already writes finished invoices into QuickBooks Online or Xero, so Paidnice reads the ledger and never needs to know whether ConnectWise, Autotask, HaloPSA or SuperOps produced the invoice. A PSA migration changes nothing on the receivables side. CloudDepot, one of its native connections, carries the ConnectWise and Autotask hop into Xero for MSPs that route billing that way. On top of the ledger it runs reminder sequences per customer group by email and SMS from your own authenticated domain, which is what lets an MSP send from accounts@ and then from a named director rather than from a platform the client has never heard of. Statements go on any schedule, including consolidated parent accounts for a client billing through several entities, and payment plans, a portal and escalation on the accounts that go quiet all sit on the same group. Its own reported outcome is a halving of the average wait for payment inside the first 30 days. Statement interest recalculates at the moment the statement sends rather than at the last policy run, so the figure a client opens is accurate that morning. The charge is calculated on the balance net of any credit on the account, and it lands on the ledger as a real receivable, which is what puts it into the client's own accounts payable queue. **Limitations with Paidnice.** The ledger mix an MSP actually runs is the constraint: QuickBooks Online and Xero are native, and a shop that has grown into Sage Intacct, NetSuite, MYOB or Dynamics 365 Business Central is on the Custom plan and a build rather than a connector, with some payment features differing between the two native ledgers. It is not a merchant account, so card and ACH run on Stripe or Pinch Payments rather than its own rails, with no surcharging function, and an MSP wanting one vendor for processing and chasing is buying two. Essentials stops at two seats, which most shops outgrow before they outgrow the invoice allowance. On the fifth criterion Chaser's 374 verified reviews are a deeper base than the 82 above. ## 2. Chaser Best for MSPs that want multi-channel chasing from a ledger-connected tool, priced by company turnover ### What is it best for? For an MSP with a named credit controller that wants email, SMS, letters and calls running from one system, and can live with one global fee rule. **Fits:** Businesses of £4m turnover and under on the entry tier, with tiers running to £200m, though Chaser's own pricing page states £100m. Not MSP-specific **Regions:** UK-registered, trading since 2014, sells worldwide. Automated calls are unavailable in New Zealand **Entry cost:** £199/mo on Compact for turnover to £4m with 4 users; Core £599/mo to £10m; Complete £899/mo above that. Verified Aug 2026 **Rated:** 4.98 from 374 [Xero App Store](https://apps.xero.com/uk/app/chaser) reviews; 4.5 from 68 on [G2](https://www.g2.com/products/chaser/reviews); 4.9 from 45 on [Capterra](https://www.capterra.com/p/157101/CHASER/reviews/), mostly dated 2020 to 2022 **Awards:** Xero App Partner of the Year 2023 **Runs on:** Xero, QuickBooks, Sage 50, Sage 200, Sage Intacct, Sage Business Central, NetSuite, Dynamics 365, AccountsIQ, SAP, HubSpot, Gmail and Outlook. No PSA connector of any kind **Late fees and interest:** Yes. Four calculation types including a UK Bank of England base rate type, recalculated daily, but one global rule only, which cannot vary by schedule or customer group, and no fee is raised on payment-plan or partially paid invoices **Does best:** Multi-channel chasing, with email sent from the team's own Gmail or Outlook mailbox plus SMS, letters and automated calls, and Creditsafe credit checking in the same tool Chaser reaches the invoice the same way Paidnice does, through the accounting ledger, so it survives a PSA change for the same reason. What it does not have is anything MSP-shaped: no PSA connector, no quoting integration, and pricing tiered by company turnover in pounds rather than by invoice volume or processing. The credit data is aimed at the moment an MSP signs a new managed-services client rather than at the moment one goes bad. A Creditsafe report inside the app carries a credit score with a recommended limit, the prospect's payment score, credit event history, and Companies House filing and director data, with continuous monitoring and a late payment predictor behind it, so an MSA can be priced and termed against something better than a gut feel about the finance director. It is UK-weighted, and checks are metered at one credit for the UK and Ireland and four elsewhere, which makes routine screening of a US client base expensive. **Limitations with Chaser.** Nothing in it is MSP-shaped: no PSA connector, no quoting integration, and no concept of an agreement behind the invoice. Pricing is set in pounds against company turnover, so a US MSP buys a UK-tiered price, and that entry price rose roughly four to five times when Chaser moved off its old invoice-count tiers. The fee engine runs a single rule for the whole client base, which is the constraint set out below. Statements go monthly only, on a fixed day, Compact caps the team at four users, and collections and forecasting are metered add-ons. ## 3. Alternative Payments Best for MSPs that want payments, payables and a human collections escalation in one platform ### What is it best for? For a US or Canadian MSP that wants card and ACH processing, accounts payable and a team that will phone an overdue client, bought from one vendor. **Fits:** Service businesses processing up to $50k a month on the entry tier and up to $100k on the second, with custom pricing above. MSPs are one of four named verticals alongside accounting, business services and telecom **Regions:** United States and Canada only. Canada excludes Quebec, and installment financing and collections are unavailable there. No published support for the UK, Australia, New Zealand or South Africa **Entry cost:** US$199/mo up to $50k of monthly processing; US$499/mo up to $100k; custom above that. Cards 2.9% + $0.30, AMEX 3.5% + $0.30, US ACH at no fee, with a published chargeback schedule. Verified Aug 2026 **Rated:** 4.7 from 11 [G2](https://www.g2.com/products/alternative-finance-alternative-payments/reviews) reviews, a thin base for a vendor citing more than 1,000 customers. No Capterra listing found **Awards:** None found **Runs on:** ConnectWise PSA, Datto Autotask PSA, HaloPSA and SuperOps. QuickBooks Online and Desktop, Xero, Sage Intacct, NetSuite, Dynamics 365 Business Central, Zoho Books and FreshBooks. ConnectWise CPQ, ScalePad Quoter, QuoteWerks and Datagate. No Kaseya BMS or Syncro **Late fees and interest:** None found. Nothing in the help center or on the receivables product pages calculates, posts or accrues a late fee or interest. The model is autopay and reminders first, then people **Does best:** Collections Assist, a success-priced escalation where their team contacts the client by email and phone, with a partner collections agency behind it Alternative Payments publishes more of its commercials than anyone else in this comparison: a monthly subscription price, a full card and ACH fee schedule, chargeback costs, and a stated zero implementation cost. It carries the widest ledger list here, and it is the only tool in this guide that does accounts payable as well as receivable, with vendor bill scanning and a bundled allowance of 50 ACH payments and 25 vendors a month. Its installment product is financing rather than a schedule you control. A client pays over 30 to 150 days in equal installments every 30 days for a fee of 3.0% to 7.0%, the fee is paid by the client, the MSP is funded in full upfront, and Alternative Payments carries the credit risk and handles missed payments. **Limitations with Alternative Payments.** North America only, and the Canadian product is materially reduced. No late fee or interest engine, so a 1.5% a month clause in your master services agreement has nothing in the platform to enforce it. Customer statements are undocumented. The analytics module has been listed as coming in July 2026 and was still marked coming soon in August. A G2 reviewer reports payouts showing as paid when the underlying transaction had failed, which sits directly on the reconciliation claim. Contract length is not published, which is the one gap in an otherwise open pricing story. ## 4. Invoiced Best for larger MSPs whose problem is billing complexity, with no published price ### What is it best for? For an MSP running billing on NetSuite, Sage Intacct or Dynamics 365 Business Central that needs invoice-to-cash breadth rather than collections depth. **Fits:** Mid-market and enterprise finance teams. No revenue band published, and the positioning has moved upmarket since the Flywire acquisition **Regions:** United States-centered. No other market is documented **Entry cost:** Not verified. No price could be confirmed from public materials at the August 2026 check **Rated:** Not verified. No review score could be confirmed from a primary source at the August 2026 check **Awards:** None found **Runs on:** NetSuite, Sage Intacct and Dynamics 365 Business Central, with maintained integration pages for Xero and QuickBooks Online, Desktop and Enterprise. No PSA connector documented **Late fees and interest:** Not verified. A late fee automation use case is published; the mechanic behind it was not confirmed at the August 2026 check **Does best:** Invoice-to-cash breadth, spanning billing, dunning and payments on ERP-grade ledgers Invoiced is a US invoice-to-cash platform, now part of Flywire, whose center of gravity has moved to the ERP end of the market: buyer pages written for CFOs, controllers and AR managers, a gated white paper library, and integrations led by NetSuite, Sage Intacct and Dynamics 365 Business Central. Xero and QuickBooks integration pages are still maintained, and they are no longer the focus. For an MSP the question is whether billing complexity or collections is the real bottleneck. Where a large MSP is running multi-entity or high-volume recurring billing, that breadth is worth paying for. Where the invoices already come out cleanly and the problem is that clients pay late, it is more platform than the job requires. **Limitations with Invoiced.** Three of the eight facts above could not be verified from public materials: the price, the rating and the late-fee mechanic. That means Invoiced cannot be scored on two of the five criteria at all, which is why it sits last rather than unranked. No PSA connector is documented, so an MSP would be relying on the ledger hop with none of the MSP tooling the platforms above carry. ## 5. FlexPoint Best for MSPs that want low per-transaction ACH and compliant US card surcharging ### What is it best for? For a US MSP whose biggest receivables cost is card and ACH fees, and which wants AI agents drafting the follow-ups it never gets around to sending. **Fits:** MSPs processing up to $50k a month on Essentials, up to $100k on Growth, and unlimited on Plus. No revenue band published **Regions:** United States. Every price, cap and rail published is USD, and no support for the UK, Canada, Australia, New Zealand or South Africa is published either way **Entry cost:** Subscription price not published. ACH is $1.00, $0.50 or $0.25 per transaction by tier, cards are Interchange+ with no published margin over interchange, and Same-Day ACH carries an included monthly allowance per tier. Verified Aug 2026 **Rated:** 4.9 from 5 [G2](https://www.g2.com/products/flexpoint-flexpoint/reviews) reviews, too small a base to read as a quality signal; the [Capterra](https://www.capterra.com/p/10024207/FlexPoint) listing carries no reviews at all **Awards:** None found **Runs on:** ConnectWise PSA, Autotask, HaloPSA and SuperOps. QuickBooks Online and Desktop and Xero on every tier, with Sage Intacct, NetSuite and Dynamics 365 Business Central above the entry tier. Quoter, QuoteWerks, ConnectWise CPQ, Rewst and Datagate. No Kaseya BMS or Syncro **Late fees and interest:** No, from your ledger only. Their own guide states that QuickBooks late fee settings sync automatically, so FlexPoint displays, communicates and collects a fee the ledger already calculated **Does best:** AR Agents, which write and send collection emails from each account's history and balance, pause when a client replies or a payment posts, and escalate to an AI voice call only after email, at thresholds you set Surcharging is the feature FlexPoint leads with, and it is built properly: the platform calculates and applies the surcharge against current US state regulations and card network rules rather than offering a flat toggle. Same-Day ACH ships with a published included allowance per tier, and the Rewst integration plugs billing into the automation layer many MSPs already orchestrate everything else with. The AI is the most substantive in this comparison and the escalation design is sensible: opt-in per capability, voice only after email, and a pending-approvals queue that surfaces what needs a human before anything goes out. **Limitations with FlexPoint.** The subscription price is invisible and the card margin over interchange is unpublished, so the published ACH rates only tell you part of the cost. Late fees are inherited rather than computed, which means an MSP with no fee logic in its ledger gets none from FlexPoint. Payment plans are a financing product whose partner, rates and terms are unpublished. A custom portal domain and GL Connect are add-ons and premium ledgers are tier-gated, so the headline feature list overstates what the entry tier includes. The contract term is governed by the order form and auto-renews, despite month-to-month marketing. Five G2 reviews is close to no third-party evidence. ## 6. ConnectBooster Best for MSPs already inside the ConnectWise or Kaseya stack, quoted price only ### What is it best for? For an MSP on ConnectWise or Kaseya BMS that wants a mature client portal and deep autopay, and can work with a quoted price. **Fits:** ConnectWise and Kaseya MSPs, and MSPs already buying the Kaseya 365 Ops bundle. No revenue or volume band published; the product is quoted **Regions:** The current product page names US-based support only. The vendor's own country list, covering the US, Canada, UK, Ireland, Australia, New Zealand and the Nordics with local card rates and local bank rails, has been deleted, so current availability is unconfirmed **Entry cost:** Not published, quote only. Their own help article describes three separate charges: the software subscription, the BNG gateway fee, and merchant card processing billed by whichever processor you are on, with ACH invoiced separately again. Verified Aug 2026 **Rated:** 4.2 from 23 [G2](https://www.g2.com/products/connectbooster/reviews) reviews; 3.8 from 12 on [Capterra](https://www.capterra.com/p/192910/ConnectBooster), the only score below 4.0 in this comparison **Awards:** G2 Leader in Billing and High Performer in Billing, Summer 2026 **Runs on:** ConnectWise Manage and PSA, Datto Autotask PSA and Kaseya BMS. QuickBooks Desktop and Online, Xero, Sage Intacct and Dynamics GP. Quoter, ConnectWise Sell, Zomentum, QuoteWerks QuoteValet, GreatAmerica, Datagate, CloudRadial and Invarosoft. No HaloPSA, SuperOps, Syncro or NetSuite **Late fees and interest:** None found. No late fee or interest topic appears anywhere in the help documentation, across configurations, autopay, billing, accounting, gateway, client emails or reports **Does best:** Autopay depth, with organization-level enrollment, an approval workflow, expiring-card handling and a configurations report ConnectBooster is the incumbent, built in Fargo in 2010 by BNG Team and acquired by Kaseya in October 2022. It is the only tool here that connects Kaseya BMS, QuickBooks Desktop and Dynamics GP, and its reporting suite is deeper than the challengers': open invoices, transactions, scheduled payments, autopay configurations, expiring and locked cards, and email history. As at August 2026 the connectbooster.com domain redirects wholesale to a single Kaseya product page. Pricing, features, the FAQ and the countries page all land in the same place, and the product is now sold as a component of the Kaseya 365 Ops bundle rather than on its own. **Limitations with ConnectBooster.** Cost is genuinely unknowable from public sources: an unpublished subscription, three separate bills and processor fees on a fourth timetable. The reviews are the weakest in this comparison and the complaints are structural rather than cosmetic, naming portal usability, sync failures that create duplicate entities, gateway timeouts and a transaction limit that blocked a payment. There are no late fees, no interest, no installment plans and no surcharging documented. Kaseya's auto-renewal terms are a live objection for buyers, and the brand no longer has an independent web presence. ## Suspension, service credits and what the MSA allows An MSP has an escalation ladder no product business has, and no software on this page can climb the top half of it. Knowing where the software stops is what stops you buying the wrong thing. The ladder, in the order it actually gets used: 1. **The reminder.** All six send one. Sender identity is the only thing that separates them here. 2. **The charge.** Paidnice and Chaser compute and raise it. FlexPoint displays whatever the ledger already computed. The other three document nothing. 3. **The account manager call.** Chaser has a one-way automated call and logged manual calls on Core and above. FlexPoint's AR Agents place an AI voice call, but only after email outreach has run. Alternative Payments sells Collections Assist, where their own team phones the client for you on success pricing. 4. **Suspension of non-critical services.** No tool in this comparison documents it, and none should. Suspension happens in the RMM and the PSA, on your engineers' authority, not on a receivables policy. 5. **Suspension of support.** The same, with a much shorter fuse on the relationship. 6. **Termination notice.** Legal, not software. Rungs four and five are where MSPs get into trouble, and the reason is the agreement rather than the tooling. Suspension for non-payment has to be an express right in the MSA, with a stated notice period and a stated cure period, or you are the party in breach. Most well-drafted MSAs also carve out anything safety-critical or security-critical, which in practice is most of what an MSP runs. That carve-out is why nobody suspends a client whose backup they operate. Pull monitoring or patching from a client mid-dispute and you own the outcome of the next incident, whatever the contract says about it. The realistic suspension list for most MSPs is new project work, non-contracted requests, hardware procurement and license expansion, which is why those are the levers experienced shops pull first. Service credits run the other way and are worth checking at the same time. If your MSA gives credits for missed service levels, a client in a payment dispute will look for them, so the AR conversation and the service review need to be held by people who have read the same document. What the software can genuinely do at these rungs is record. A dated log of every reminder, every charge, every call and every promise is what turns rung six from an argument into a paper trail, and it is worth switching on long before you expect to need it. ## Applying a late fee to a client on a three-year MSA Two of these six compute the charge themselves. Paidnice runs a policy per customer group, Chaser runs one global rule, FlexPoint passes through whatever QuickBooks calculated, and no fee or interest mechanic is documented for Alternative Payments, ConnectBooster or Invoiced. Most MSAs already carry a late payment clause, commonly 1.5% a month on overdue balances. Writing the clause was never the hard part. Applying it to a client whose CTO you are having lunch with next week is the hard part, and it is the reason the clause so often sits unused for years. So grain decides this rather than existence. Chaser's late fee is one global rule that cannot vary by schedule or customer group, and it raises no fee on payment-plan or partially paid invoices, so a flagship client on a three-year MSA and a month-to-month break-fix account are treated identically or not at all. Paidnice's policies sit under customer groups, so a managed-services group on net 30, a project group and a disputed-accounts group each run their own rule at the same time. The pattern that survives contact with an account manager is to switch the charge on for the groups that need it, leave the flagship group at zero, and move an account between groups when its behavior changes. That is a conversation somebody can have. The alternative is a single global rule that fires on the wrong client once and gets quietly disabled the same afternoon. A charge that has landed is also something to give up. Waiving it deliberately, in writing, in exchange for payment this week works on an MSA client precisely because it reads as a concession from you rather than as a penalty they have to argue their way out of. One global rule (Chaser) - Four calculation types, including the UK base rate - Recalculated daily - One rate for every client - No fee on payment-plan or part-paid invoices A policy per customer group (Paidnice) - Flat, percentage or compounding interest - Multiple policies running at once - An invoice fee and a statement charge together - Raised on the ledger as Draft or Approved The two tools that compute the charge themselves, compared on whether the rule can tell a flagship MSA client apart from a break-fix account. Alternative Payments, ConnectBooster and Invoiced document no fee mechanic, and FlexPoint passes through whatever the ledger calculated. ### Simple against compounding, across a recurring book Where the tool computes the charge it can compound it. Where somebody raises it by hand once a quarter, it never does. On one invoice the gap is rounding. Across a book of managed-services invoices that all sit three months out, on the same clients, every month, it stops being rounding. Worked example. On $12,000 overdue for 3 months at 1.5% a month, a simple late fee is $540.00 and a compounding one is $548.14, a difference of $8.14. Change the balance, the months and the rate to model your own MSA clause across a recurring book. A simple fee multiplies the balance by the monthly rate by the months overdue. A compounding fee charges each month on the balance including the fees already added, which is why the gap widens on a recurring book rather than on one invoice. The rate itself comes from your MSA and from the ceiling your state sets, so confirm both before the first policy runs. ## What breaks when you change PSA ConnectWise to HaloPSA is the migration this market has been running for three years, and it is the event that decides whether a receivables tool bought today is still yours in 2029. Three things happen to the receivables side when the PSA changes. - **A native connector has to exist for the new PSA, or the tool leaves with the old one.** Alternative Payments and FlexPoint both cover ConnectWise, Autotask, HaloPSA and SuperOps, so a Halo migration is survivable on either. ConnectBooster covers ConnectWise, Autotask and Kaseya BMS and documents neither HaloPSA nor SuperOps, so the same migration ends it. No tool here documents a Syncro connector at all. - **A ledger-based tool never learns the migration happened.** Paidnice and Chaser read QuickBooks Online or Xero, and the new PSA writes finished invoices into the same ledger the old one did. The reminder schedules, the customer groups and the fee policies all carry across untouched. - **Stored payment mandates may or may not travel.** Autopay enrollments and stored cards live with the processor rather than with the PSA or the receivables tool, so the real question is whether the migration also changes processor. Ask before you commit, because re-enrolling every client on autopay is the cost nobody budgets for. Then the ledger underneath, which changes far less often and rules out more tools: - **QuickBooks Online and Xero.** All six reach them. - **QuickBooks Desktop.** Alternative Payments, FlexPoint, ConnectBooster and Invoiced. Not Paidnice, and not Chaser. - **Sage Intacct, NetSuite and Dynamics 365 Business Central.** Alternative Payments, Invoiced and Chaser as standard, FlexPoint above the entry tier, and Paidnice on its Custom plan as a build. - **Dynamics GP.** ConnectBooster alone. Put a number on it before you sign. If you expect to change PSA once in the next five years, a PSA-bound tool is a five-year purchase with a rebuy in the middle, plus a re-implementation and a second round of client communications about how they pay you. A ledger-bound tool trades the PSA-native invoice view for not having that conversation twice. ## Installments against financing, and who carries the risk Paidnice and Chaser schedule installments against an open invoice. Alternative Payments and FlexPoint sell financing instead, which is a different product with a different balance sheet. No installment function is documented for ConnectBooster, and Invoiced could not be verified. The distinction decides who is exposed if the client fails. An installment plan against your own invoice leaves the receivable and the credit risk with the MSP. A financing product settles the invoice in full, charges the client a fee, and moves the default to the provider. Alternative Payments splits 30 to 150 days into equal installments every 30 days at a fee of 3.0% to 7.0% paid by the client, funds the MSP upfront, carries the risk itself, and does not offer it in Canada. FlexPoint lists working capital and financing on every tier and publishes no partner, no rate and no term. On the scheduling side, ConnectBooster documents scheduled and recurring payments, which are future-dated charges rather than one invoice split into a schedule. What each tool does with an installment that fails, and what the plan does to the aged report and the tax point, is set out on the [payment plan software guide](/reviews/best-payment-plan-software/). For an MSP there is a third option neither category covers: renegotiating the agreement itself. A client who cannot pay a monthly invoice is often on the wrong plan rather than in distress, and moving them down a service tier recovers more revenue over three years than an installment schedule on one arrears balance. ## Sizing it: solo MSP to multi-entity Seat count and client count decide this better than turnover does, because an MSP's invoice volume tracks the number of agreements rather than the size of the deals behind them. - **Owner-operator, under about 20 clients.** One monthly invoice run, no finance hire, and the whole job is that nobody chases. Paidnice at US$69 a month covers 150 invoices and two users, which is the entire billing operation at this size. - **Small shop, 20 to 60 clients, one bookkeeper.** Still Paidnice on invoice volume, with the seat cap the reason to move to Pro. Alternative Payments at US$199 where the same decision is also a decision to move processor and buy payables at the same time. - **Growing MSP, 60 to 200 clients, a finance person.** This is where client groups start to earn their keep, because the flagship accounts and the long tail now need different treatment. FlexPoint enters here if ACH volume is high enough that $1.00 against $0.25 a transaction is real money and surcharging is something you intend to use. - **ConnectWise and Kaseya shops, any size.** ConnectBooster arrives bundled inside Kaseya 365 Ops, which is a distribution advantage no amount of product beats. Price it against the three separate bills rather than against the bundle line. - **Multi-entity and acquisitive MSPs.** Invoiced where billing complexity across entities is the actual bottleneck, or Chaser's Core and Complete tiers for multi-channel chasing and credit data on one system. Consolidated parent-account statements matter more here than any other feature, because one client group now spans several billing entities. ## What MSP receivables software costs in 2026 Entry prices verified August 2026: Paidnice US$69 a month, Alternative Payments US$199 a month up to $50k of processing, Chaser £199 a month. FlexPoint publishes transaction rates but no subscription. ConnectBooster and Invoiced publish nothing at all. Three different meters are in play, and they scale against three different things. Alternative Payments and FlexPoint price by monthly processing volume, so the bill steps up when a large client renews rather than when the software does more. Chaser prices by company turnover, in pounds, so a US MSP is buying against a UK band. Paidnice prices by invoice volume on a flat tier with no per-seat fee above the entry plan, which for an MSP tracks client count rather than contract value. That distinction is worth a moment on a recurring book. An MSP that doubles its average contract value without adding clients pays more to two of these vendors and the same to a third, for identical work. Then count the bills. Only Alternative Payments publishes both the subscription and the card and ACH rates in one place. FlexPoint publishes ACH per transaction and puts cards on Interchange+ with no stated margin. ConnectBooster arrives as three separate charges on three timetables before merchant processing, and no Invoiced price could be confirmed from public materials at all. ## MSP receivables questions What MSP owners ask once the shortlist is down to two: whether a PSA integration is needed, which tools can actually raise a charge, and what the agreement lets them do about a client who will not pay. ### What is the best accounts receivable software for MSPs? For an MSP billing through QuickBooks Online or Xero, Paidnice, because it applies late fees and compounding interest as a separate policy per customer group and posts the charge to the ledger, from US$69 a month. For an MSP that wants payments, payables and a human collections escalation from one vendor, Alternative Payments, from US$199 a month up to $50,000 of monthly processing. Both were verified in August 2026. ### Does MSP accounts receivable software need a PSA integration? No. Alternative Payments, FlexPoint and ConnectBooster maintain native PSA connectors. Paidnice and Chaser take the other route: the PSA already writes finished invoices into QuickBooks Online or Xero, so the tool reads the accounting ledger and works for any PSA. The practical difference shows up at migration, when a native connector has to be replaced and a ledger connection does not. ### Which MSP tools charge late fees and interest automatically? Paidnice and Chaser. Paidnice runs flat, percentage and compounding charges as a policy per customer group and raises them on the ledger as Draft or Approved. Chaser has four calculation types behind a single rule applied to every client alike. FlexPoint passes through a fee that QuickBooks calculated, Alternative Payments and ConnectBooster document no fee mechanic, and Invoiced could not be verified. ### How much does MSP accounts receivable software cost? All figures below were verified in August 2026, and none of them includes card or ACH processing, which is priced separately on every tool here and compared on the gateway guide. Paidnice publishes US$69 a month for Essentials, covering 150 invoices and up to 2 team members, with Pro from US$99 and no per-seat fee. Alternative Payments publishes US$199 a month up to $50,000 of monthly processing and US$499 up to $100,000. Chaser publishes £199 a month for turnover to £4m. FlexPoint publishes ACH at $1.00, $0.50 or $0.25 per transaction but no subscription price. ConnectBooster is quote-only, and no Invoiced price could be confirmed. ### Can an MSP charge 1.5% a month on overdue invoices? Your MSA has to provide for it and your state has to permit the rate, so confirm both before you set a policy. What the software decides is narrower and more practical: whether the charge is raised at all without somebody remembering, whether it compounds, and whether the rule can be softer for the clients you least want to argue with. On $12,000 overdue for three months at 1.5% a month, a simple fee is $540.00 and a compounding one is $548.14. ### Do I still need AR software if my PSA sends invoices? A PSA issues the invoice and stops there. It does not escalate by client group, charge a late fee on the ledger, send statements on a schedule or report on collection performance. Issuing the invoice is the cheap part of receivables; what happens on day 45 is the part that changes when a client pays. ## How this page was built, and by whom Accounting.Events publishes it. No vendor pays to be on the page, and no vendor pays for its position on it. The MSP-specific claims, PSA coverage, fee grain and what survives a migration, come from vendor documentation and help centers rather than from sales pages, because that is the only place any of it is stated precisely enough to compare. Prices are quoted in the currency each vendor prints, with no conversion applied, and every entry-cost line carries the month it was checked. None of them includes card or ACH processing. Ratings carry the platform and the count, and none of these review bases is MSP-specific, which is worth knowing before weighting them heavily. Where a vendor documents nothing, the cell says so rather than guessing, and Invoiced carries three unverified facts for exactly that reason. Everything here was re-read in August 2026 and is re-read on every update. The section on suspension describes contractual practice rather than legal advice, so read your own MSA before acting on it. ## More for MSP finance Buyer's guide ### Best accounts receivable software (by business type) The whole category ranked by business size and accounting system.
