Quick answer
Most overdue invoices are not bad faith, they are forgetfulness and process. The money is lost in the awkwardness of asking: someone has to notice, someone has to write, and usually everyone assumes someone else will. Receivables monitoring takes that duty off the team and watches due dates in the background. At Syntalith we price it as separate lines, net:
- free process scan (€0): a 30-minute engineer call plus a written takeaway in two business days,
- receivables monitoring automation (from €3,500 net): the system watches invoices, matches them against payments, and runs escalating reminders,
- typical range for this process (€3,500–8,000 net): depending on bank and accounting integration and the number of scenarios,
- maintenance (priced individually): hosting, monitoring, template and rule changes after launch.
The full price list for every line is on the Syntalith pricing page. If you want a portable document with architecture and a fixed quote before a bigger decision, the current price of the implementation specification is €1,200 net. These are indicative net prices; the Polish market context below is cited in PLN because that is how the source reports it.
Why invoices go overdue in the first place
Because paying on time is someone's process, not a reflex, and at your counterparty that process can be as leaky as chasing is at yours. The problem is not marginal. According to the Skaner MŚP survey for BIG InfoMonitor and BIK (Q2 2026, n=500), 87% of firms report that their counterparties pay invoices late, and 74% say overdue receivables materially hurt the business.
The scale of money frozen in delays is growing too. Total overdue business liabilities (30+ days, above PLN 500) reached about PLN 46.2 billion at the end of February 2026, up 5.7% year on year (BIG InfoMonitor, 2026). Among firms that sell on deferred payment terms, more than half have receivables overdue by more than a month, and about 29% wait longer than two months (BIG InfoMonitor, December 2025, n=500). Little wonder that 76% of firms plan anti-backlog measures in 2026.
This is the cost nobody usually counts: not the loss on a single unpaid invoice, but cash trapped for weeks across dozens of invoices at once, often financed with a working-capital line. And the reminder that would shorten it never goes out, because it is uncomfortable.
What receivables monitoring actually does
It watches three things people dislike watching: what was issued, what came in, and what follows from that. The system knows your issued invoices (from the invoicing system, accounting, or the national e-invoicing platform) and matches them against payments from the bank or accounting. When a due date approaches or passes without payment, it fires the right rung of the reminder ladder. All of it in your firm's tone, not in the impersonal language of an automaton, and every step is logged: when it went out, to whom, with what content, and what the counterparty replied.
The escalation ladder is explicit and you set its thresholds. Below is a typical layout; the last column, who triggers it, matters most.
| Step | When | Tone | Who triggers it |
|---|---|---|---|
| Polite reminder | 3–5 days before due date | soft, "for good order" | automated, by template and schedule |
| Reminder after due date | 1–3 days after due date | plain, neutral | automated, by approved template |
| Follow-up | 7–14 days after due date | firm, still courteous | automated or human, depending on amount |
| Formal demand for payment | 21–30 days after due date | formal, with consequences | a human always approves the draft |
| Escalation decision | above threshold | outside the reminder channel | always a human (lawyer, collection agency) |
The routine steps, the polite reminder and the first reminder after the due date, can go out on their own, using approved templates and a schedule. Those are the ones that recover most overdue invoices, because most delays really are forgetfulness. The heavier steps are prepared by the system but not sent without a decision.
Where the automation stops and the human begins
The line is simple: the automation reminds, the human decides on escalation. A formal demand for payment, negotiating an instalment plan, and the decision to hand the matter to a lawyer or a collection agency always go through a human. The agent never threatens, never sets settlement terms, and never negotiates on its own. It prepares a draft demand with the right amount, invoice number, and dates, and a human reads it, edits it, and either sends or holds it.
This boundary is not caution for show. A payment reminder is a relationship with a client you usually want to keep, so the tone and the timing carry commercial weight, not just financial. That is why the heavier steps stay with the human who knows the context: that this client is about to place a bigger order, that another had an outage, that a third is better called than written to. The system removes the routine and the watching, not your judgement.
What it costs and whether it pays back
Implementation starts from €3,500 net, and you calculate payback on your own numbers, not on our promise. Start with the cost of the backlog itself, the cash trapped in overdue invoices:
Annual cost of the backlog =
invoices on deferred terms per month
x average delay in days
x average invoice value
x (annual cost of working capital ÷ 365)Then add the time of the people who chase payments manually today:
Annual cost of manual chasing =
hours per week on reminders and checking receipts
x hourly rate of the people doing it
x 52If the sum of those two lines is clearly higher than the cost of building and maintaining the system, monitoring pays back, mainly by shortening the delays, because a faster reminder means a faster receipt. If it comes out lower, we will advise against building it. Do not count revenue you cannot measure, and remember that your best-paying clients would pay without a reminder anyway; the real gain is on those who forget.
What about the phone? That is a separate channel
Receivables monitoring works in the text channel: email and messages. Phone calls are a different product and a different risk, so we do not fold them into one automation. Telephone payment reminders and inbound calls are handled by the odbierze.ai voicebot, covered in the piece on the AI voicebot for debt collection. If your process genuinely needs to call the debtor, that is the right place, not an email the client will ignore.
When NOT to build receivables monitoring
Honestly: there are situations where this is a bad purchase, however real the market's backlog problem is.
- A handful of invoices a month. If you issue a dozen or so invoices a month, a calendar reminder and a ready email template are enough. The implementation will not pay back, and a simpler habit solves it.
- One large non-paying client. If the real problem is a single counterparty who will not pay despite reminders, that is not a job for automation but for a lawyer or a collection agency. The automation will send a tenth reminder to someone who has already decided not to pay.
- Messy payment data. If it is unclear which payment matches which invoice, because accounting and the bank account live apart, fix payment matching first. An automation on uncertain data will chase invoices already paid, which is worse than silence.
Worth hearing before you buy: monitoring shortens delays caused by forgetfulness, but it does not change the decision of a client who deliberately withholds payment. That takes a different tool and a different budget.
How to start
The cheapest sensible first step is to cost the backlog, not to buy a tool.
- Book a free process scan and show how payment chasing looks today.
- Prepare: how many invoices a month you issue on deferred terms, what the average delay is, who reminds clients today, and how you know an invoice has been paid (bank, accounting, e-invoicing platform).
- After the call you get a recommendation: monitoring automation, an implementation specification, the phone channel in odbierze.ai, or an honest "a calendar and a template are enough for now."

FAQ
What is AI receivables monitoring?
It is a system that watches your issued invoices, matches them against incoming payments from the bank or accounting, and sends escalating reminders in your firm's tone: polite before the due date, firm after it, and a formal demand as a draft for a human to approve. Every step is logged. Implementation starts from €3,500 net, and the first step, a free process scan, costs €0.
What runs on its own and what stays with a human?
Routine reminders (polite before the due date and the first one after it) can go out on their own, using approved templates and a schedule. A formal demand for payment, negotiating instalments, and the decision to escalate to a lawyer or a collection agency always go through a human. The agent never threatens and never negotiates on its own.
How much does receivables monitoring cost to implement?
Automating one process starts from €3,500 net, typically €3,500–8,000 net, depending on bank and accounting integration and the number of reminder scenarios. You calculate payback on your own numbers: invoices on deferred terms times average delay times the cost of working capital.
Can phone reminders be automated too?
The phone channel is a separate product. Inbound calls and telephone payment reminders are handled by the odbierze.ai voicebot, covered in the piece on the AI voicebot for debt collection. Receivables monitoring covers the text channel: email and messages.
When does receivables monitoring not make sense?
If you issue a handful of invoices a month, a calendar and an email template are enough, not an implementation. If the real problem is one large client who will not pay despite reminders, you need a lawyer or a collection agency, not reminder automation.
