How it works

Your part takes three steps.

Everything happens in the document portal, the online service where you send your receipts. You don't need to sort or name them. The portal is in Finnish, and our English guide explains every button.

  1. The portal's login page: email, password and the Kirjaudu (Log in) button.
    1

    Log in

    You get an invitation link by email when you become a customer. After that you log in with your email and password.

  2. The documents page: drag files into the box or pick them with the Valitse tiedostot (Choose files) button.
    2

    Send your receipts

    Drag receipts and bank statements onto the page, or take a photo of a receipt with your phone. AI reads them and suggests the entries.

  3. The home view: an example company's figures (cash, monthly sales and costs, VAT payable), with documents, invoicing and agent access, and the next due date.

    Follow your numbers

    You see cash, sales, costs and VAT payable about 15 minutes after booking. You create sales invoices in the same place.

AI and people

AI does the repetitive work. People make the decisions.

This is how the work is divided in practice.

AI

  • reads receipts and invoices
  • suggests an entry for each one
  • checks that the bank statement and the books match

Accountant

  • checks the AI's suggestions
  • files the reports with the Tax Administration
  • prepares the financial statements and is responsible for them
Your accountant

Call, and a person answers.

Because AI does the routine work, your accountant has time for your questions. The same person handles your bookkeeping from start to finish.

Questions

What business owners ask first.

Is your question missing? Call +358 41 327 4326 or write to flow@syntropia.fi.

What is an AI accounting firm?

An accounting firm where AI does the repetitive work: it reads receipts and invoices, suggests the entries and compares the bank statement with the books. An accountant checks the work, files the reports and prepares the financial statements, and is responsible for them.

Can I switch from my current accounting firm?

Yes. We collect your records from your previous accounting firm and make sure the bookkeeping continues without a break. Switching costs nothing.

Do I need accounting software?

No. You send your receipts to the portal, and we do the rest. See the portal

Can I use the service in English?

Yes. You can write to us in English. The portal is in Finnish for now, and our English guide explains every button you need. Read the guide

Who is responsible if the AI makes a mistake?

Syntropia Oy is responsible for the quality of the bookkeeping. The accountant checks the AI's work before the reports and financial statements. An error found later is corrected, and every correction stays visible in the books. You are responsible for the receipts and invoices you send being correct.

We are registered in the anti-money laundering supervision register of the Finnish Supervisory Agency (Lupa- ja valvontavirasto), LVV-U/128176/2026.

What is not included in the price?

Foreign trade costs €50/month + VAT. Payroll is priced in a quote. Other special reports are done only if we have agreed on them in advance.

What is a pilot customer?

During the pilot, we do your bookkeeping alongside your current bookkeeping. After that you get the same service permanently 60 % cheaper than what you pay now. Ask about a pilot place

How long is the contract?

The contract is valid until further notice, and there is no notice period. When you leave, we hand your records over to you or to your new accounting firm. Otherwise we follow the general terms of the Finnish accounting sector, TAL2023 (PDF in Finnish).

Can AI help my own business too?

Yes. Syntropia also offers AI consulting alongside bookkeeping. Read about consulting (in Finnish)
