AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
An AI finance agent can track overdue balances, flag debts that are becoming doubtful, propose a provision and prepare the paperwork for a write-off or tax relief claim. It should not write off a customer balance itself: deciding that a debt will not be collected, and ending the chase, is a commercial and sometimes legal judgement for a person.
Overdue, doubtful and bad
Not every late invoice is a bad debt. It helps to separate three stages, because each calls for different action in the books:
- Overdue
- Past its due date but still expected to be paid. The invoice stays in debtors and the chase continues.
- Doubtful
- There is real reason to think it may not be paid, such as a dispute, broken promises or news that the customer is in difficulty. Many businesses record a provision, reducing the reported value of debtors without removing the invoice.
- Bad
- You have concluded it will not be collected. The debt is written off, which removes it from debtors and records the loss.
Moving a debt from one stage to the next is a judgement. An agent can supply the evidence; it should not make the call alone.
What the agent watches
- Ageing: how long each balance has been overdue, by customer and in total.
- Payment behaviour: whether a customer who used to pay in 30 days now takes 75.
- Promises: dates a customer committed to and whether they were kept.
- Disputes: open queries or complaints linked to the invoice.
- Partial payments: small amounts paid against a large balance, often a sign of strain.
- Concentration: how much of your total debtors sits with one customer.
From these, the agent can list balances it considers at risk each month, with the reasons. Entities reporting under IFRS 9 estimate expected credit losses; a small business may use a simpler policy, such as providing for a percentage of balances over a set age. Agree the approach with your accountant, and the agent can apply it consistently.
Write-offs and tax relief
A write-off may allow tax relief, but the rules are specific and differ by country. Two examples:
- UK VAT. HMRC's VAT Notice 700/18 explains that VAT-registered businesses can generally claim bad debt relief on VAT already paid to HMRC if the debt has been unpaid for at least six months from the later of the due date and the date of supply, it has been written off in the accounts, and the claim is made within four years and six months. Other conditions apply.
- US income tax. The IRS explains that to deduct a business bad debt you generally must have included the amount in income or lent cash, the debt must be worthless, and you must show reasonable steps to collect it. Cash-method taxpayers generally cannot deduct unpaid fees they never recorded as income.
These are summaries for general information. An agent can track the dates and evidence each rule needs, and remind you when a debt first becomes eligible, but whether and when to claim is for you and your adviser.
A ceiling for write-offs
| Item | Suggested handling |
|---|---|
| Rounding or bank-charge differences under a small set amount | Agent writes off within its limit |
| Overdue balance, no dispute | Agent continues the agreed reminder sequence |
| Balance with an open dispute | Brought to a person; chase paused while resolved |
| Balance the agent rates as doubtful | Provision proposed; person approves |
| Any customer balance write-off | Person decides; agent records the reason |
| Write-off for a connected party or staff member | Owner or board only |
The last row matters for control. Writing off a debt is also a way to hide a payment that was diverted, which is why the decision should never rest with the same person, or agent, that collects the money. For approval design more generally, see who should approve payments in a small business.
A worked example
Example only, in US dollars. A contractor has $64,000 in debtors. At the June close, the agent flags three balances:
- $5,200 from a client 95 days overdue with two missed promised dates and a partial $500 payment. The agent proposes a 50% provision under the agreed policy. The owner approves.
- $1,800 from a client who has disputed the work. The agent pauses reminders and links the dispute record. The owner decides to offer a credit of $600.
- $340 from a business that has closed, with returned letters and no reply. The agent prepares a write-off with the collection history attached. The owner approves after asking the accountant about the tax position.
Notice that the agent treated the three cases differently. The first had a pattern of broken promises, the second a dispute about the work, the third a customer that no longer exists. A single rule such as 'write off anything over 90 days' would have handled all three badly, which is why the categories above call for a person.
Each decision is recorded with who made it and why, which is the evidence a tax authority or auditor would expect to see.
Where Pryme fits
On a Pryme Business account, the Finance agent manages working capital, including the debtors position, and works only inside its mandate; write-offs above the line you set come to you with the evidence. The Sales agent keeps the record of promises made by customers, and the Chief of Staff brings the decisions together so you see them in one place.
Questions people ask
When should I write off a bad debt?
When you have concluded, on the evidence, that it will not be collected. Your accountant can advise on timing for accounts and tax.
Is a provision the same as a write-off?
No. A provision reduces the reported value of debtors while you keep chasing; a write-off removes the debt and records the loss.
Can I still chase a debt after writing it off?
Generally yes. If money is later received, it is recorded as a recovery. Check any tax adjustments with an adviser.
Can I charge interest on late business debts?
In the UK, GOV.UK explains that businesses can usually claim statutory interest of 8% plus the Bank of England base rate on late business-to-business payments, unless the contract sets a different rate. Other countries differ.
