Accounts Receivable AI ROI Calculator
Collections is two costs at once: the hours a person spends chasing invoices, and the cash that sits unpaid while they do it. This page prices both. Set the reminder volume and your hourly cost below, then your DSO in the second block.
The calculator opens with 1,500 collections touches a month: reminders, statement requests and dispute triage, 6 minutes each for a person at 35 euros an hour, against a model reading the invoice and the thread (1,500 input, 300 output tokens) with a person checking three out of ten before they go out, and a 14,000 euro representative build. The DSO block below it is separate: enter your invoiced revenue, your current DSO and the days you expect to cut, and it shows the cash released and what that cash costs you today.

What a shorter DSO is worth
The calculator above prices the reminders. This block prices the cash that arrives earlier. Enter your own numbers; nothing here is assumed.
Daily revenue: €500,000 × 12 / 365 = €16,438
Cash released: €16,438 × 7 = €115,068
Financing saved: €115,068 × 8% = €9,205
Cash released is working capital you stop financing, not profit. Use the yearly financing saving in the business case and the cash figure when liquidity is the constraint.
What AI actually automates in accounts receivable
Collections is a sequence of small, repeated, well-documented touches, which is exactly what a model does well. A first build usually covers:
- 01Reminder sequences written per customer: tone, language and the exact invoice details pulled from your ERP, sent on the schedule you set and stopped the moment payment lands.
- 02Dispute triage: the reply that says the price is wrong, the goods never arrived or the PO number is missing gets classified and routed to the right person with the invoice attached.
- 03Remittance matching: payments that arrive without a reference are matched to open invoices by amount, customer and date, with the uncertain ones queued for a person.
- 04Promise-to-pay tracking: a customer who says Friday gets a note on Friday, not a generic reminder on the next cycle.
- 05The aging report as a conversation: which accounts moved past 60 days this week, who has not answered twice, where the exposure is concentrated.
Realistic ranges to expect
The per-touch saving is the easy part: a reminder written and checked by a model costs cents against a few euros of a person's time, and the calculator shows it per reminder, per month and per year. The DSO effect is where the money is and where the honesty matters. The calculator does not assume a reduction. Enter your own: teams that go from ad hoc chasing to a consistent sequence usually see single-digit days, and the published benchmarks below say most AI users report six days or more. Put in a conservative number first and see what one day is worth.
Cash released is not profit. It is working capital you stop financing: the yearly saving in the block is that cash times your cost of capital, which is the number a CFO will accept. If you are cash constrained, the released amount itself is the argument.
What the research says
Dated, sourced numbers on DSO and AI in receivables, vendor-published where noted:
In October 2025 Wakefield Research, in a study commissioned by Billtrust of 500 finance decision makers at North American companies with revenue over 250 million dollars, found that 99 percent of companies using AI in receivables had reduced their average DSO, with 75 percent reporting a reduction of six days or more.
Billtrust's 2026 benchmark report, published in March 2026, put its clients' average DSO at 39 days in 2025, six days better than 2024, and cited Allianz Research's 2025 figure of a global DSO around 50 to 54 days, with 44 percent of companies above 60 days.

MIT's Project NANDA reported in July 2025 that about 50 percent of enterprise GenAI budgets go to sales and marketing while the highest measured returns come from back-office automation such as document processing, exactly where receivables work sits.
How to read the result
Two numbers, two audiences. The per-reminder cost is for the operations lead: it shows the team stops writing the same email 1,500 times a month. The DSO block is for finance: it turns days into cash. Present them separately, because the second one depends on an assumption you make, not on a price list. Both benchmarks above come from a vendor of AR software, so treat six days as the optimistic edge and defend your case with a smaller number.
Accounts receivable ROI questions
01Will customers know a model wrote the reminder?
The reminder goes out from your mailbox in your tone with the real invoice details, and a person reads the share you set before it leaves. Customers see a consistent, polite, well-timed sequence. That consistency is what moves DSO, not the wording.
02Which systems does this connect to?
Anything that exposes invoices and payments through an API: Xero, QuickBooks, Sage, Microsoft Dynamics, SAP Business One, Odoo, or a bank statement export. Reminders go through your existing mailbox so replies land where they always did.
03How do I pick the DSO reduction to enter?
Start from your own aging report: how many days late is the typical invoice that eventually pays without a dispute? A consistent sequence usually recovers part of that. Enter a third of it as the conservative case and the whole of it as the goal.
04What does a collections automation project cost?
Reminder sequences on one mailbox and one accounting system start around 4,000 euros; the task default assumes 14,000 euros for a fuller build with dispute triage and remittance matching. The figure is fixed in writing after a free scoping call.
