How it works

The agent prepares. You confirm. Purser keeps the books straight.

  1. 1

    Connect your agent

    Purser gives you an instruction to paste into Claude Code or Codex, and the agent connects itself. It works on your real records, under the same rules as the app.

  2. 2

    Ask for what you need

    Invoice a client, book receipts, reconcile the bank, run payroll. The agent does the groundwork and leaves a proposal in Purser.

  3. 3

    Review and confirm

    See exactly what will be posted and why. One click and it's done. Or ask the agent to redo it.

Trust

You have the final say. An agent that runs your finances has to earn that trust.

Swedish Bookkeeping Act (bokföringslagen), ch. 5 § 6
”För varje affärshändelse ska det finnas en verifikation.”

Every business event must have a voucher.

That's why every business event in Purser gets a voucher, with its evidence attached.

  • Nothing is posted without your yes.

    Everything the agent does is a draft until you confirm it in Purser.

  • Corrections, never deletions.

    Posted events are fixed with correction vouchers. The original always stays.

  • Purser never touches your money.

    Payments are made in your bank. Purser records and reconciles them.

  • The rules have sources.

    Purser is built on the Swedish Bookkeeping Act, the VAT Act, K2 and Skatteverket's guidance. The rules are documented with quotes from the source text.

  • You sign.

    Declarations are filed only after you've reviewed and approved them.

  • Your data can always leave.

    Export all your books as SIE 4 whenever you like, to an accountant or another program.

Why Purser exists

Built by someone who needed it.

When I started ASF Studio AB, I bought bookkeeping software, paid a year up front, and then pushed the bookkeeping to next month. Every month.

Meanwhile I was doing more and more of my work with AI agents. So I built what was missing: a real bookkeeping system an agent can work in, with rules, history and a human who confirms.

The idea is simple. A limited company should run on a bank account, an AI agent and Purser. The rest of your time is yours.

My own company's books are kept in Purser. Want to run yours alongside?

FAQ

Questions

Who is Purser for?

People running their own Swedish limited company (aktiebolag), for example as a consultant or freelancer, keeping books under K2. Purser is built for companies where the owner is the only person on payroll.

Is it real bookkeeping?

Yes. BAS chart of accounts, vouchers with evidence, journal and general ledger, VAT return, payroll with AGI basis, guided year-end close and SIE 4 export. An auditor will feel at home.

Which AI agents work?

Claude Code and Codex (ChatGPT) are supported today. Other agents that speak MCP work too. You run the agent on your own subscription.

Do I need to know how to code?

No. Purser gives you an instruction to paste into Claude Code or Codex, and the agent connects itself. During the beta I'll help you get set up.

Do I have to use an agent?

No, you can do everything directly in Purser. The agent takes care of the groundwork: reading statements, linking receipts, creating drafts and emailing invoices once you've approved them.

What if the agent gets it wrong?

Nothing is posted without your approval. If something is still wrong, it's fixed with a correction voucher and the original stays. You can always see what was done and why.

Which banks are supported?

Any bank that exports statements as CSV or camt.053. With Lunar, the agent can fetch statements for you. Purser never makes payments; those happen in your bank.

Does Purser file my declarations?

Purser produces the basis for VAT and AGI. The agent can help you file with Skatteverket, but you review, approve and sign yourself. Agent-assisted filing is in beta. INK2 and the annual report are prepared outside Purser, and Purser reminds you of the dates.

What isn't included?

The annual report and the income tax return (INK2) are prepared outside Purser, by you or your accountant. Payments are made in your bank. Agent-assisted filing with Skatteverket is a preview.

Can I switch from Fortnox or Bokio?

Purser can import your previous books via SIE, and the agent helps with the move. During the beta we do it together.

Who can see my data?

You, and the agents you connect yourself. You can export all your books as SIE 4 whenever you like.

What does it cost?

Nothing during the beta. After launch, Purser costs 129 SEK a month with everything included.
