How it works

From the bank to finished books, without you in the middle.

  1. 01

    Connect or drop in

    Starling, Revolut, Wise, Mercury and Qonto sync every day, read-only. Any other bank, in any country: upload the statement as a CSV, PDF or spreadsheet.

  2. 02

    Finn sorts it

    Every transaction categorised using what Finn knows about your business. Your own rules, like "Uber is travel", always come first.

  3. 03

    Finn matches it

    Customer payments close their invoices. Spending finds its receipt or bill. The books reconcile themselves.

  4. 04

    You check the odd one

    Anything Finn is not sure about waits in one short list. Everything else is already done.

Connect

Connect once. It keeps up by itself.

Link your business account and Finn brings in new transactions every morning. The connections only read your transactions: Finn cannot move money.

  • Starling, Revolut Business, Wise, Mercury and Qonto sync every day, read-only
  • Every currency account comes in as its own account: each Wise balance, each Revolut pocket
  • Take card payments through Stripe? Payouts, fees and refunds come in daily as well
  • Coming soon: Open Banking for UK bank accounts and credit cards. It is built and in beta, and switches on as soon as our provider moves us to production

Any bank

Any bank, any country. Just drop the statement in.

Not on a connected bank? Download a statement and drop it in. Finn works out the layout itself, whatever the bank or country, so there is no template to set up.

  • CSV from any bank: Finn reads the columns and checks with you if a layout is new and unclear
  • PDF statements, including scanned ones
  • Excel files and Google Sheets
  • Upload a statement that overlaps a connected bank feed and Finn keeps one copy

Your rules

Tell Finn once. It remembers.

Finn categorises every transaction using what it knows about your business. When you want something done a particular way, make it a rule, in the app or just by telling Finn. Your rules always win.

  • Match on the description or the payee: contains, exact or starts with
  • Set the category, and the contact too if you like
  • Ask Finn in chat and it can file the matching transactions that are not categorised yet
  • Change a category yourself and it stays changed

Finn on the app

Put everything from Uber under travel from now on

Done. New rule: anything from Uber goes to Travel. I've also filed the 14 Uber payments that weren't categorised yet.

Illustrative example

Reconciled

Reconciled while you sleep.

After every sync, and every statement you upload, Finn matches what came in: customer payments close their invoices, spending finds its receipt or bill. The confident matches are done. The rest wait for you in one list, and Finn leaves you a note in your updates.

  • Paid invoices close themselves, and their reminders stop
  • Receipts that arrived first are matched when the payment lands
  • Anything uncertain goes on a short review list, not into your books
  • Run it yourself any time with Reconcile with Finn, and get an email when it is done

FAQ

Banking: common questions

Which banks connect directly?

Starling, Revolut Business, Wise, Mercury and Qonto sync every day. Stripe brings in card payments. Open Banking for other UK bank accounts and credit cards is coming soon: it is built and in beta. Until then, upload a statement from any bank.

Can Finn move money from my account?

No. The bank connections only read your transactions. AccountsOS never sends payments from your account.

My bank isn't listed. Can I still use AccountsOS?

Yes. Download a statement as a CSV, PDF or spreadsheet from any bank in any country and drop it in. Finn works out the layout for you.

What if Finn puts something in the wrong category?

Change it and it stays changed. If it keeps happening for the same payee, make a rule, or just tell Finn and it will make one.

Can I have accounts in more than one currency?

Yes. Each currency account is its own account, and the books convert everything into your home currency.

What happens if I upload a statement my bank feed already covered?

For Starling, Revolut and Wise, Finn spots the overlap and keeps one copy of each transaction.
