AI agents for finance

In a small business, money is almost never lost at the invoicing stage. It is lost at the chasing stage. The invoice goes out, nobody pays, and three weeks pass before anyone notices — because chasing is thankless, easily postponed, and never looks urgent on the day itself. That is exactly the kind of work an agent holds without tiring.

1. What an agent takes on

Four tasks take up most of the administrative time tied to money, and delegate well because they follow a statable rule and can be checked at a glance.

Issuing quotes and invoices — from what was agreed, with the right legal mentions and the right payment schedule, without re-entering what already exists in the customer file.
Watching what has not been paid — spotting invoices whose due date has passed, and flagging it the day it becomes true rather than the following month.
Chasing — writing the follow-up in your tone, at the right moment, taking into account how old the delay is and the relationship with the customer.
Preparing the paperwork — gathering what goes to the accountant, filed and complete, rather than a file reconstructed in a rush at the end of the quarter.

What these four tasks have in common: none requires accounting judgement, only consistency and punctuality. That is precisely what a business owner does badly, because they have better things to do and nothing forces them on a Tuesday morning.

2. The case of unpaid invoices

It is by far the best first project. It meets the four criteria of good delegation: it comes back constantly, its rule fits in one sentence, its result shows up in the bank account, and a mistake is fixed with a word.

Late payment is almost never a refusal to pay. It is an oversight, an invoice lost in an inbox, an approval chain dragging on at the customer's end. The first follow-up resolves most cases — provided it actually goes out. An agent sends it that same day, without you having to decide whether the moment is right.

What matters in the setting is not the frequency, it is the tone. A follow-up that is too curt with a good customer costs more than the invoice; one too soft with a bad payer produces nothing. You set that scale, the agent applies it — and holds to it even in the week you are not thinking about it.

3. What stays with the accountant

This has to be stated plainly, because it is the first objection that comes up and it is a fair one.

nullbot does not do accounting. It does not connect to your bank accounts, posts no entries, produces neither balance sheet nor tax return, and in no way replaces your accountant. What it holds is the administrative work before accounting: what has been invoiced, what has been collected, what is dragging.

And that is good news for the accountant too. What costs them the most hours is not the technical side — it is chasing missing paperwork and untangling incomplete files. A client whose invoicing is up to date and whose records are filed is a client they handle faster, and often for less.

4. What you must not entrust to it

Three things stay on the human side, and not for technical reasons.

Paying. No money should ever be able to leave through an automated system, whatever the trust granted. An agent prepares a payment, it does not trigger one. It is the simplest rule to hold and the most expensive to break.

Granting an extension or writing off a debt. Spreading a payment, waiving penalties, booking a loss: these are decisions that bind the company and set a precedent with the customer. They go through a validation, not because an agent would be incapable, but because their cost is real.

The final stage of debt recovery. A formal notice, a payment order, ending a commercial relationship: at that point it is no longer a matter of consistency but of strategy, and often of law. The agent brings you there with the complete file; it does not walk through the door.

5. Measuring the result

Three figures are enough, and the first almost suffices on its own.

Average time to payment — the number of days between issuing an invoice and collecting it. It is the indicator that moves fastest once follow-up becomes systematic, and the one you see directly in cash flow.
The share of overdue invoices chased within the deadline — the one you set yourself. It should trend towards all of them; if it stalls, the rule is badly formulated, not badly applied.
Human rework time — how many minutes a week you spend correcting the agent before a follow-up goes out. If it does not fall, it is the tone scale that needs revising.

Tracking that produces handsome dashboards but speeds up no collection has automated nothing: it has added surveillance to a problem that called for action.

6. Frequently asked questions

Does nullbot connect to my bank?

No. It reads no bank account and triggers no payment. Tracking collections is based on what you or your agents observe and record. That is a deliberate limit: a system with no access to the money cannot send it out by mistake.

Does it replace my accountant?

No, and that is not the aim. nullbot holds the administrative work upstream — invoicing, chasing, filing — so that your accountant receives a clean set of records. Accounting, filings and advice remain their profession, and they will do it all the better for spending less time asking for missing paperwork.

Do follow-ups go out without my seeing them?

Only if you decide so, and by type of situation. At first the agent submits every follow-up to you; once the tone suits you, you let those concerning small ordinary delays go out alone and keep a validation on important accounts or sensitive cases.

Where should I start?

With monitoring alone, and no automatic follow-up. Within a week you will see the real list of what is overdue — and that surprise is often what decides the rest. Follow-ups open up afterwards, starting with the smallest amounts.
