For many finance teams, matching is where the loose minutes disappear: pick up a bank transaction, work out which invoice it belongs to, link it, next. So the question of whether AI can take it over comes up often. The honest answer is partly, and it is worth knowing exactly which part.
Can AI match my bank statements?
The proposal yes, the final link no. An assistant can retrieve your outstanding items, line up the bank transactions and say per line which invoice it probably is, including the ones it is unsure about. What it cannot do over the connection is actually link that payment to that invoice. That happens in Exact Online.
What matching actually does
A payment on your bank account is at first just an amount with a description. Matching is the act of connecting that transaction to the outstanding item it belongs to. Only after that does your debtor position hold up, does the invoice drop out of your reminder list, and do your ageing reports mean anything.
Which is exactly why the step is sensitive: a wrong link does not show up in a total, but it does propagate into your reminders and your VAT. The error is quiet, and that makes it expensive.
What the connector can do today
| What you want | Tool | Read or write |
|---|---|---|
| Retrieve outstanding items | financial_outstanding_get | read |
| Search receivables | cashflow_receivables_search | read |
| Debtor ageing report | financial_aging_receivables | read |
| Inspect existing bank entries | financial_bank_search, financial_bank_get | read |
| Create a bank entry | financial_bank_create | write |
| Add a line to that entry | financial_bank_add_line | write |
Those six get you a long way: you can have the assistant work out which invoices are still open, what the amounts are and which bank line sits closest to each.
Where the line is
There is no tool that links a payment to an outstanding item. Two things that regularly cause confusion:
cashflow_receivables_updatesounds like it does, but only updates the description, payment method and payment reference of a receivable. It changes no amount and no status.financial_cash_add_line(for cash entries) has no Our reference field. Of the two routes, only the bank route can carry an invoice number.
Why Our reference is the field that matters
On a bank line against a debtor, Our reference is the field that says which invoice this is about. financial_bank_add_line accepts it as ourRef, alongside the account (accountCode), the GL account and the amount. Fill that in properly and the entry is ready with everything needed to make the link — turning the last step in Exact Online into a confirmation rather than a search.
The workflow that does work
- Ask for the proposal. For example: "Which invoices for customer Bakkerij de Groot are outstanding, and for what amounts?" Then line up the bank transactions and have the assistant say which invoice fits each amount.
- Ask for the doubtful cases. Explicitly ask which transactions cannot be matched unambiguously. That list is worth more than the easy ones.
- Confirm yourself. Create the entry (or have it created) and finish the match in Exact Online.
This is not a stopgap while waiting for something better. It is the shape that fits an action which can fail quietly: the assistant does the searching, you do the confirming.
Where it goes wrong in practice
- Partial payments — an amount that does not equal the invoice. The assistant can propose the combination, but the remainder is your judgement.
- Bulk payments — a customer paying five invoices in one amount. Ask for every combination that adds up to the amount; that is exactly the work where arithmetic beats searching.
- Credit notes — they reduce the amount due and are easily overlooked.
- Bank charges and rounding — small differences you have to deliberately put somewhere.
- Currency differences — with foreign currency the amount on your account is rarely the invoice amount exactly.
What you need
Basic is enough for querying and comparing: that is all reading. If you want the assistant to create the bank entry as well, you need Advanced, because those are write tools. If read-only is enforced for a colleague, those tools are refused even on Advanced — which is the entire point of that setting.
