◆ Invoice Collection Agent

Get paid faster — without losing the customer

Every day an invoice sits unpaid, your own cash funds someone else's business — but chasing is awkward, manual, and always deprioritised. Our Invoice Collection Agent chases every overdue invoice with a professional, personalised, escalating cadence, predicts and prioritises likely late payers, makes paying a click away, and routes genuine disputes to a human. Cash comes in faster, DSO drops, and the relationships you worked hard to win stay intact.

Where cash gets stuck

The collection problems that lock up your cash

Late payment rarely comes from unwillingness — it comes from chasing that's manual, inconsistent, badly timed, or aimed at the wrong accounts. Click a panel to see the problem, how the agent fixes it, and what changes.

01Cash tied up
DSO

You did the work, sent the invoice — and the money just sits there

Every day an invoice stays unpaid is a day your own cash is funding someone else's business. Receivables climb, days sales outstanding stretches, and working capital you've already earned is locked in a spreadsheet of overdue accounts.

💡Our fix: The agent chases every overdue invoice on time, every time, with a structured escalating cadence from the due date onward — so payments come in sooner and your cash stops sitting in other people's bank accounts.

02Nobody chases
Manual Effort

Chasing invoices is everyone's job, so it's nobody's

Following up on late payers is tedious and awkward, so it slips down the list behind everything else. Reminders go out late or not at all, only the squeakiest accounts get chased, and the rest quietly age.

💡Our fix: The agent does the chasing tirelessly and consistently — never too busy, never forgetting — so every overdue account is followed up properly, not just the few someone found time for.

03Awkward tone
Relationships

Chase too hard and you lose the customer; too soft and you lose the cash

Collections is a tightrope. Aggressive reminders damage relationships you've worked hard to build; timid ones get ignored. And when different people chase in different tones, the experience your customers get is inconsistent and off-brand.

💡Our fix: The agent strikes the balance — polite, professional, personalised reminders that escalate appropriately and stay on-brand — so you get paid without souring the relationship, consistently across every account.

Prioritisation

You waste effort on accounts that would have paid anyway

Treating every overdue invoice identically means burning effort on customers who always pay a few days late, while the genuinely risky, high-value accounts get the same generic nudge — and slip further.

💡Our fix: The agent predicts who's likely to pay late, prioritises by risk and value, and tailors the approach to each account — so attention goes where it actually protects cash, not where it's wasted.

05Disputes stall payment
Disputes

An unanswered query is holding up an invoice nobody's chasing

Often an invoice is unpaid not from unwillingness but a genuine query — a PO mismatch, a missing credit note, a delivery question. Chased with a generic reminder, it stalls; the customer feels unheard and the payment sits.

💡Our fix: The agent detects when an account is disputing or querying rather than simply late, and routes it straight to a human to resolve — instead of firing another reminder — so blockers get cleared and the invoice gets paid.

What it does

What the Invoice Collection Agent Handles

From the first gentle reminder to a paid invoice — chasing every overdue account professionally and smartly, while disputes and sensitive cases go to a human.

Runs a structured, escalating reminder cadence on every overdue invoice — from a gentle pre-due nudge through to firmer follow-ups — sent on time, every time, so no account slips through and chasing never depends on someone remembering.

Case studies

Invoice Collection Case Studies

Three teams that pulled cash in faster — and kept their customers.

Manufacturing

DSO cut without a single angry customer

Challenge: A manufacturer's receivables kept climbing because chasing was manual and always deprioritised, and inconsistent when it did happen.

Solution: The agent chased every overdue account with a professional escalating cadence, predicted late payers, and routed disputes to the credit team.

-32%days sales outstanding
Fastercash collection
Zerorelationship damage
SaaS & Subscriptions

Failed-payment dunning that recovered revenue

Challenge: A SaaS business lost recurring revenue to failed card payments and lapsed invoices that nobody had time to recover.

Solution: The agent ran smart dunning across channels with easy re-payment links, and escalated genuine issues to a human.

Recoveredat-risk revenue
Fewerinvoluntary churns

Professional Services

Collections that scaled without a bigger team

Challenge: A services firm's growing invoice volume outpaced its small finance team, so overdue accounts aged and cash lagged.

Solution: The agent handled routine chasing at scale, prioritised high-value overdue accounts, and surfaced only exceptions to the team.

Firm on cash, fair on people

Collections Done the Right Way

Getting paid can't come at the cost of your customers or your compliance. We build the agent to chase professionally, respect fair-collection rules, keep humans on the sensitive cases, and stay accurate.

🤝

Professional, never harassing

Reminders are courteous, appropriately paced and escalate reasonably — they never badger or pressure. Collections should protect the relationship as much as recover the cash, and we design the tone to do exactly that.

🙋

Disputes and sensitive accounts go to a human

When a customer is querying an invoice, or the relationship is delicate or high-value, the agent hands off to a person rather than firing another reminder. It chases the straightforward; humans handle the sensitive.

📜

Built for fair-collection rules

How you may chase a debt is regulated — especially for consumer debt, where rules like fair-debt-collection laws apply, and requirements differ by country. We build to the practices and limits where you operate, and recommend your legal or compliance team reviews the approach.

🧑‍💼

Humans decide escalation, plans and write-offs

Payment plans, sending an account to a collections agency or legal, and write-offs are business decisions the agent never makes on its own. It recommends and prepares; a person decides.

🎯

Accurate — it won’t chase the wrong thing

The agent works from your real, current AR data and reconciles against payments received, so it doesn’t dun a customer who has already paid or chase an incorrect amount. Wrongful chasing damages trust, and we design against it.

🔐

Customer and financial data kept secure

Customer, invoice and payment data is handled with encryption, access control and retention limits, and used only to manage and collect your receivables.

Frequently Asked Questions

It’s an AI agent that chases your overdue invoices to get you paid faster. It runs a structured, escalating reminder cadence on every overdue account, writes personalised and professional messages, predicts and prioritises likely late payers, makes paying easy with clear balances and payment links, and — importantly — routes disputes and sensitive accounts to a human rather than chasing them. It brings down days sales outstanding and frees up working capital, while protecting the customer relationships behind the invoices.

It’s designed specifically not to. Reminders are courteous, personalised, on-brand and escalate at a reasonable pace — a professional nudge, never harassment. Genuine disputes and sensitive or high-value relationships are handed to a person rather than chased automatically. The aim is to recover cash while keeping the relationship intact, and consistent professional tone across every account usually improves the experience compared with ad-hoc manual chasing.

It predicts which accounts are likely to pay late based on history and behaviour, and prioritises by both risk and invoice value — so effort concentrates on the accounts that genuinely threaten cash, not the reliable ones that always pay a few days late. The cadence and firmness escalate appropriately over time, and you set the rules and limits it works within.

The agent recognises a query or dispute as different from simple late payment, stops sending reminders on that item, and routes it to a human to resolve — with the context and history attached. Often an invoice is unpaid because of a real issue like a PO mismatch or a missing credit note, and firing another reminder just frustrates the customer. Getting these to a person quickly clears the blocker and gets the invoice paid.

How you may pursue a debt is regulated, and the rules are strictest for consumer debt — fair-debt-collection laws in the US and equivalents elsewhere govern tone, timing and contact, and requirements differ by country and between consumer and business debt. We build the agent to respect fair-collection practice and the limits where you operate, and we recommend your legal or compliance team reviews the approach. We’re software engineers, not lawyers, so the professionals who own that risk should sign it off.

No — those are business decisions it never makes on its own. For persistent non-payers or accounts heading toward a collections agency or legal action, the agent escalates to your credit team with a full history and a recommended next step, and a human decides. The same applies to payment plans and write-offs: it prepares and recommends; you decide.

No — it works from your live AR data and reconciles against payments received, so it stops chasing the moment an invoice is settled and won’t dun a customer who has already paid or chase an incorrect amount. Wrongful chasing is one of the fastest ways to damage trust, so accuracy against real, current data is built in.

We integrate with accounting and ERP platforms like QuickBooks, Xero, NetSuite, Sage and Microsoft Dynamics, billing and collections tools, and payment providers like Stripe, GoCardless and PayPal, plus email, SMS and portal channels for outreach. It acts on your live receivables and reconciles against payments. In-house or custom systems integrate via their API.

No — it removes the repetitive chasing, not the team. Routine follow-up on hundreds of accounts is exactly what a small finance team can’t keep up with; the agent handles that at scale and surfaces only the exceptions — disputes, sensitive accounts, escalations — that need human judgement. Your team spends its time on the accounts and decisions that actually need people.

A collection agent for a defined ledger can typically pilot in a few weeks — we set up cadences and messaging, integrate your accounting and payment tools, add dispute routing and escalation, then scale. Cost depends on invoice volume, channels and integrations; we usually start fixed-scope so you see the value quickly, then expand. The initial assessment call is free.
