A payment arrives. Everything else just happens.

This is the loop other tools make you run by hand: import, code, match, mark paid. Here it runs itself.

01

Payment lands in Wise

A customer pays an invoice into any currency balance in your Wise Business account.

02

It syncs into your books

The direct feed pulls it in every day, automatically.

03

Finn categorises it

AI coding with your company context and your own bank rules applied first.

04

The invoice flips to paid

Reconciliation runs automatically, confident matches apply, your ledger posts, and you get a 'done' message. Exceptions wait for one-tap review.

Finn, your AI accountant

Chat to your bank. Literally.

Finn is connected to the feed. Ask in plain English and he pulls fresh transactions from Wise on the spot, then reconciliation follows automatically.

  • "Has the payment from Acme landed yet?"
  • "Check my bank and reconcile anything new."
  • "What's my USD balance?" (the real one, as Wise reports it)
  • "What did that EUR to GBP conversion actually cost me?"
Finn, has the $6,000 from Northstar come in?
Just checked your Wise USD balance, yes, $6,000 from Northstar Ltd landed 18 minutes ago. I've matched it to invoice INV-0057 and marked it paid. Your USD balance is $11,110.20.
Nothing else needs you, your GBP and EUR balances are unchanged and already categorised.

Every currency balance

GBP, EUR, USD and 40+ others, each Wise balance becomes its own account in your books, and currency conversions are recorded correctly on both sides.

Read-only, by design

The connection uses a read-only API token. AccountsOS can never move your money. Create it in Wise, disconnect it any time from either side.

Your token, encrypted

The API token belongs to your company. It's stored AES-256 encrypted and never appears in logs.

Built for founders trading internationally

Multi-currency without the spreadsheet

Most accounting tools bolt currency conversion on as an afterthought, one blended balance, guessed exchange rates, a reconciliation headache every month-end. Wise gives you a real balance in every currency you trade in, and AccountsOS treats each one as its own account. When you convert GBP to EUR inside Wise, both sides of that conversion land in your books correctly, so your P&L and balance sheet always match what actually happened in the bank.

Frequently asked questions

How does AccountsOS connect to Wise Business?

Through a read-only API token you create yourself, in Wise go to Settings > API tokens, generate one, and paste it into AccountsOS. No Open Banking aggregator sits in between. Setup takes a couple of minutes; the full walkthrough is in the setup guide.

Is the connection read-only?

Yes. The token is read-only, AccountsOS can see balances and transactions but can never move your money. It's stored AES-256 encrypted, and you can disconnect it at any time from either Wise or AccountsOS.

Does it reconcile payments against invoices automatically?

Yes. Every sync that brings in new transactions automatically dispatches a reconciliation run. Incoming payments are matched to open invoices and marked paid, spending is matched to receipts and bills, and confident matches post to your ledger. Anything ambiguous waits in a review queue, you only see exceptions.

Which Wise balances sync?

All of them. Every currency balance in your Wise Business account, GBP, EUR, USD and 40+ others, becomes its own bank account in AccountsOS, and currency conversions are recorded correctly on both sides.

Does Wise only work for UK businesses?

No. Wise Business is built for founders trading internationally, and the AccountsOS connection works the same way worldwide, it isn't limited to UK accounts.

Can I ask Finn about my Wise account?

Yes. Ask Finn 'has the payment from Acme landed?' or 'what came in last week?' and Finn answers from your Wise transactions, which sync every day.

How does multi-currency accounting actually work?

Each Wise balance is treated as its own bank account with its own currency. When you convert between balances inside Wise, both sides of the conversion are recorded, so your books always reconcile to the real currency movement, not a single blended GBP figure.

Can AccountsOS pay bills from Wise?

Not yet, the Wise connection is a bank feed: balances and transactions sync in, and Finn reconciles them against your invoices and bills automatically. Outbound payments still happen in Wise itself.

Do I need a specific Wise plan?

You need a Wise Business account to generate an API token. The connection itself is free in AccountsOS, it's included as a connector on every plan.

A couple of minutes to connect. Then it's Finn's problem.

14-day free trial, then £20/month. The Wise connection is included on every plan.
