The best AR automation software for B2B collections is the one that matches who you want doing the collecting. Accounts receivable (AR) tools split three ways: software that organises your team’s chasing, enterprise suites that automate parts of the cycle, and autonomous platforms where an agent runs the cycle and your team handles exceptions. This guide compares nine tools on the same six criteria, with a source beside every claim.
Nine AR automation tools at a glance
One table, six questions a finance director asks in the first demo. A dash means the vendor does not publish the answer, and we did not guess it.
| Platform | Who does the chasing | Payments included | ERP write-back | Processor requirement | Typical deployment | Entry pricing |
|---|---|---|---|---|---|---|
| Finero | Fin. Autonomous agent | Hosted card + ACH pages | Line-level, posted to ERP | Keep your existing processor | Core: 0-1 days; custom: 1-2 weeks | From $399/mo |
| Stuut | Autonomous agent | Processes incoming payments | - | - | Days (vendor claim) | Not published |
| HighRadius | Predictive worklists for your team | Customer portal | Cash application | - | - | Not published |
| Billtrust | Collections workflows (your team) | Payments portal | Cash application | - | - | - |
| Versapay | Your team + collaborative buyer portal | Portal payments | Cash application (AI) | - | 4-6 weeks (mid-size avg.) | - |
| Tesorio | Your team, with AI payment predictions | - | - | - | - | - |
| Upflow | Your team, organized by Upflow | - | - | - | - | Free analytics tier; automation quoted (ARR-based) |
| Chaser | Reminder-led (your team's cadence) | - | Two-way sync (Xero/QBO) | - | - | Custom (volume-based), free trial |
| Monto | Not a chasing tool | Payment happens in the buyer's portal | - | - | - | Not published |
Read the first column twice. “Your team, organised by…” and “autonomous agent” describe different operating models, and everything else in the comparison follows from that choice.
How we selected the best AR automation software
This is a Finero-authored guide, and Finero is on the list. Read it as a structured look at the market by a vendor in it, with the working shown, rather than as an independent test. Two rules kept it honest. Every competitor fact traces to the vendor’s own site or a named publication, linked beside each review, and anything we could not verify is left blank rather than estimated. Facts were checked on 7 September 2026.
We scored every tool on the same six criteria, the columns in the table above:
- Who does the chasing: your collectors, or the software.
- Whether payment is inside the loop, or a link to somewhere else.
- What gets written back to the ERP, and at what level of detail.
- Whether you keep your payment processor, or adopt the vendor’s.
- Time to live, using the vendor’s own published number.
- Entry pricing, as published. Quote-only is recorded as quote-only.
Nine is the shortlist a mid-market finance team would actually get through. A longer list would have been easier to assemble and harder to use. If a tool you run is missing, it is because we could not verify enough about it to fill the row.
The nine AR automation tools, reviewed
1. Finero
Best for: B2B finance teams that want collections executed rather than organised, without changing their ERP or payment processor.
Finero is an autonomous accounts receivable platform. Its agent, Fin, decides per invoice what happens next: chasing over email, SMS and chat, taking card and ACH payment on hosted pages through the processor you already have, triaging buyer disputes, and posting line-level cash application back to NetSuite, SAP, Oracle Fusion, Dynamics 365, QuickBooks Online or Xero. Exceptions go to your team. Routine volume does not.
The commercial shape is the part most of this list does not publish. Core is $399 per month, includes 200 successfully paid invoices, and charges 0.1% of the amount collected on each invoice past that, capped at $1. There are no per-seat licences and no implementation fee, and it starts with a 30-day trial. Core goes live in 0 to 1 days; custom implementations take 1 to 2 weeks. Scale, for higher volume and enterprise ERPs, is priced individually.
The honest boundary: Finero is a young platform in a category that did not exist three years ago. A team that wants a decade of G2 history should weigh that against the autonomy gap in the older tools below. Check the ERP and processor integrations for your stack, then see how it works on your own invoices.
2. Stuut
Best for: enterprise finance teams that want an autonomous order-to-cash agent and do not need published pricing to start a conversation.
Stuut describes its platform as an AI coworker for accounts receivable. Its product scope spans outreach, payment handling and cash application, with billing-contact discovery and voice outreach among its published capabilities. Confirm which modules are available today when discussing your rollout.
Pros: Finds billing contacts; Voice outreach alongside email and SMS.
Cons: Starting price not listed on product page; Credit module still listed as coming soon.
Sources:Product
3. HighRadius
Best for: large enterprises with the IT capacity to run a full order-to-cash transformation programme.
HighRadius covers a broad finance-software scope, including credit, deductions, treasury and financial close. Its AR modules can be implemented individually or together. The buying decision therefore includes which modules you need and how the quoted commercial model will apply to your business.
Pros: Credit and deductions modules; Treasury and financial-close tools.
Cons: Pricing requires module and integration scoping; Outcome-based fees vary with realized gains.
Sources:Products and pricingFee model
4. Billtrust
Best for: enterprises consolidating invoicing, payments, and cash application in one suite.
Billtrust combines accounts receivable products with credit management and ERP-connected B2B commerce. Its offering spans several products and services, so a useful evaluation separates the invoicing subscription, payment processing and any additional capabilities your team plans to use.
Pros: Credit application and risk tools; ERP-connected B2B webstores.
Cons: Invoicing subscription includes 10 seats; extras cost more; Payment processing carries separate transaction fees.
Sources:ProductsSeat limitsPayment fees
5. Versapay
Best for: mid-market teams whose collections stall on buyer collaboration and disputes.
Versapay brings invoicing and customer collaboration into a shared portal, alongside collections and payment capabilities. Its published migration guide describes a 90-day process for moving from another AR solution. Treat that as context for a migration discussion, rather than a timeline for every deployment.
Pros: Shared customer portal for invoice queries; Prepayment and early-discount options.
Cons: Starting price not listed on product page; Published migration guide describes a 90-day process.
6. Tesorio
Best for: teams that want strong cash-flow forecasting alongside collections workflows.
Tesorio connects receivables work with cash-flow visibility and forecasting. Its Salesforce connection brings customer context into collections and sends customer notes back to the CRM. Integration details matter: invoice-note synchronization and flat-file setup have specific limits to check before purchase.
Pros: Cash-flow forecasting tools; Customer notes sync back to Salesforce.
Cons: Invoice notes do not sync to Salesforce; Flat-file connections require automated exports and SFTP.
7. Upflow
Best for: teams that want AR visibility, analytics, and organized human collections workflows.
Upflow offers a free analytics plan and paid collections plans with unlimited user seats. Paid tiers are organized around annual invoiced revenue, invoice volume and feature access, including AI capabilities on selected plans. Budget around the ledger you expect to manage as the business grows.
Pros: Free AR analytics plan; Unlimited user seats on paid plans.
Cons: Paid plans require a yearly commitment; Plans cap invoiced revenue and invoice volume.
Sources:Plans and limits
8. Chaser
Best for: smaller B2B teams on Xero or QuickBooks who want reminder-led chasing plus credit checking.
Chaser combines receivables software with an optional human AR support service called Care. Its published plans set different allowances for users, workflows and forecasting. Compare the software subscription and the managed-service add-on separately if you are considering help with day-to-day collections.
Pros: Optional human AR specialist; Receivables forecasting on higher plans.
Cons: Compact limits users and automated workflows to four; Human AR support is a paid add-on.
Sources:Plans and limits
9. Monto
Best for: suppliers whose invoices have to be filed inside customer AP portals such as Coupa, SAP Ariba or Amazon.
Monto focuses on invoices that must be delivered into customers' accounts-payable portals. It checks invoice data, submits documents and tracks invoice and purchase-order status. That makes portal delivery the main question to assess when deciding whether it addresses your collection bottleneck.
Pros: Invoice delivery across customer AP portals; Purchase-order and portal-status tracking.
Cons: Focus centers on customers using AP portals; Portal delivery can take up to 24 hours; usually within one.

What AR automation software costs
Six of the nine vendors here do not publish a starting price. That is the market convention, and it makes a budget conversation harder than it needs to be, so here is everything the nine publish, and nothing they do not.
- Finero: $399 per month for Core, 200 paid invoices included, 0.1% of the amount collected on each additional paid invoice, capped at $1. No seats, no setup fee.
- Upflow: a free analytics plan, with paid collections plans quoted against annual invoiced revenue and invoice volume, on a yearly commitment.
- Chaser: published plans set by volume, with a free trial; the human AR support service is a paid add-on and the Compact plan limits users and workflows to four.
- HighRadius: an outcome-based fee model in which fees vary with realised gains, scoped per module and integration.
- Billtrust: the invoicing subscription includes 10 seats with extras charged, and payment processing carries separate transaction fees.
- Stuut, Versapay, Tesorio and Monto: quote only.
The number to compare is cost per invoice collected. The subscription line is one input to it. Add seats, payment fees and overage to the licence, divide by the invoices you expect to collect through it, and set that against the collector time and the write-offs the tool is supposed to remove. A $399 plan and a quote-only enterprise suite can be the same price per invoice at one volume and a multiple apart at another. Our guide to accounts receivable automation walks through that arithmetic.
How to choose B2B collections software
Start with the problem costing your team the most hours. Inconsistent chasing, disputes that never reach the right person, invoices stuck in a customer’s AP portal, or payments waiting to be matched: each of those points at a different tool on this list, and a shortlist built from the problem beats one built from a feature checklist.
Then run the same test in every demo. Take one overdue invoice and follow it through a customer reply, a partial payment and the final ERP update. Ask who handles each step and write the answer down. The tools that organise your team will show you a worklist; the tools that execute will show you a completed invoice and an exception queue. That is the whole difference, and it is visible in fifteen minutes.
Measure the result in the numbers your CFO already reads: DSO, the overdue balance by age bucket, collector hours per invoice, and write-offs. Our guide to reducing DSO explains which parts of the cycle move each of them, and the B2B payment collection guide covers the operating models in more depth.
If the problem is that chasing itself is eating your team’s week, put an autonomous platform on the shortlist and let it run on your own invoices before you decide. What autonomous AR means sets out where that model fits and where it does not.
