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
A UK small business can receive euros into a sterling account, which converts on arrival, or into a euro balance with its own IBAN, which lets EU clients pay by SEPA transfer and lets you choose when to convert. Either way the books and VAT records are kept in sterling, so each euro receipt needs a consistent exchange rate, which an AI finance agent can apply and record.
The main ways to receive euros
| Option | How the client pays | What happens to the money | Watch for |
|---|---|---|---|
| Sterling account, international transfer | SWIFT transfer in EUR | Converted to GBP on arrival at the receiving bank's rate | Rate margin and fees on both sides |
| Euro balance with an IBAN | SEPA credit transfer, as if paying a local supplier | Stays in euros until you convert | Conversion cost later; check who holds the funds |
| Card or payment link | Client pays by card | Settled to you in a currency you choose, less fees | Card fees, chargebacks |
| Marketplace or platform payout | Paid by the platform | Often converted by the platform | Platform rate and timing |
For a business with regular euro clients, a euro balance with an IBAN usually makes the client's life easier. Eurozone businesses can pay a SEPA-reachable IBAN cheaply and quickly, and you avoid an automatic conversion at a rate you did not choose. If you also pay suppliers in euros, you can pay them from the same balance without converting twice.
Before choosing, check three things. Who holds the euro funds and under which regulation, since protection for e-money balances differs from bank deposits. Whether the euro details are in your business's own name, so clients see the right payee. And what it costs to convert back to sterling, shown as a rate and a fee before you accept, not discovered on the statement.
When to convert
Holding euros means taking currency risk: if the euro weakens against sterling before you convert, you receive fewer pounds. Converting everything on arrival removes that risk but may cost more if the rate you get is poor. Many small firms set a simple rule, such as converting enough each month to cover sterling costs and holding what they will spend in euros. An agent can apply such a rule and show what each conversion cost against a reference rate, but the decision to change the rule, or to make a large one-off conversion, should be a person's.
VAT and record-keeping in sterling
Your accounts and VAT returns are kept in sterling. HMRC lets you convert foreign currency amounts for VAT using a consistent method, such as its published period rates or a market rate, as long as you use it consistently. For many UK businesses selling services to business clients in the EU, the place of supply rules mean the sale is outside the scope of UK VAT, with the customer accounting for VAT in their own country under the reverse charge. Sales of goods exported to the EU and sales to EU consumers have different rules. This is exactly the kind of treatment to agree with an adviser once and then encode.
- Show the client's VAT number on business-to-business invoices where the reverse charge applies, with the wording your adviser recommends.
- Record the euro amount, the sterling amount and the rate used on every invoice and receipt.
- Keep the conversion method the same across periods.
- Treat exchange gains and losses as your accountant advises; they can affect profit.
A worked example: a UK web agency with German clients
This is an illustrative example. An agency in Cardiff bills three German clients a combined €18,000 a month for design and development retainers, and pays a Polish freelancer €4,000 a month. Previously the euro payments arrived in its sterling account and were converted automatically, and the freelancer was paid with a separate conversion back into euros.
With a euro balance, the clients pay by SEPA transfer. The finance agent matches each receipt to its invoice, records the sterling value at the agency's chosen rate, and pays the freelancer from euros after the owner approves. Once a month it proposes converting the balance above a €5,000 working float, showing the rate and fee before the owner accepts. The owner sees one line in the morning brief: euros received, euros paid, proposed conversion. The double conversion on the freelancer's pay disappears, and the VAT records show the outside-scope treatment the accountant set up.
Where agents help, and where they should stop
- Matching euro receipts to invoices, including partial payments and bank charges deducted in transit.
- Applying the agreed exchange-rate method and storing the rate with each entry.
- Chasing late euro invoices in the client's language and time zone.
- Flagging currency exposure above a level you set.
- Stopping before any conversion or payment above your threshold, and before any change to VAT treatment.
Agents also make mistakes here. A payment that arrives short because an intermediary bank deducted a fee can look like an underpayment by the client; a good agent checks the remittance and asks before chasing. Exchange rates on old invoices should never be overwritten when a payment arrives at a different rate: the difference is a gain or loss to record, not an error to hide.
Where Pryme fits
A Pryme Business multicurrency account holds GBP, EUR, USD and NGN on one ledger, each with local account details. Money stays in the currency it arrived in until you choose to convert on the Swap screen. The Finance agent reconciles every currency and raises exposure above your band. Outside Nigeria, Pryme operates through regulated partners. For dollars, read How a UK business can receive US dollars.
Questions people ask
Can EU clients pay my UK business by SEPA?
Yes, if you have a euro account or balance with an IBAN reachable through SEPA. Ask your provider whether its euro details support SEPA transfers.
Do I charge UK VAT to EU business clients?
For many business-to-business services, the place of supply is the customer's country, so UK VAT is not charged. Goods and consumer sales differ. Check with an adviser.
Which exchange rate should I use in my books?
HMRC accepts a consistent method, such as its published rates or a market rate. Agree one with your accountant and apply it every time.
Is it better to hold euros or convert them?
It depends on whether you have euro costs and how much currency risk you can carry. A simple written rule, reviewed quarterly, works for most small firms.
