AI for accounting firms

From manual entry to automated bookkeeping.

Do you have 3 to 30 people keeping the books for 50 to 500 clients? Then you know how much time retyping incoming invoices eats. I set up an AI that reads them for you, classifies them against your chart of accounts and pushes them into Minimax, Pantheon or Synesis.

Built for Croatian accounting firms

This work is built around Croatian bookkeeping software (Minimax, Pantheon, Synesis) and the Croatian e-invoicing scheme. If you run an accounting firm elsewhere the same automation applies, but the integrations differ: talk to me directly.

I calculate conservatively: 75 per cent automation (the field says 80 to 92, and I leave room for handwritten invoices and special cases) plus a 5 per cent error cost on top.

I will email you the itemised calculation and a suggestion for which first step would make sense for your firm. No calls, no pushing for one. The email arrives within a few minutes.

What actually hurts

Four places where a firm loses hours every week.

This is what I hear from owners of firms with 3 to 30 people working for 50 to 500 clients. Where there is an amount, it comes from the calculator above, for a firm with 30 clients.

Typing in incoming invoices by hand

A bookkeeper opens the PDF and retypes the company ID, date, amount and line items into Minimax or Pantheon. Eight to twelve minutes per invoice. That has not changed in years; it only grows by hiring more people.

About 30,000 EUR a year for a firm with 30 clients

Mandatory e-invoicing since January 2026

Your clients already receive e-invoices in the CIUS-HR format. Without automation your team pulls them off the FINA Moj-eRačun portal by hand, for each client separately. The volume grows, the headcount does not.

More work with every new client

“Where is my invoice?”

The question arrives through five channels: phone, email, WhatsApp, Viber and in person at the door. The team answers the same question several times a day instead of clients seeing the status themselves.

The same question, five channels, every day

There are no bookkeepers on the market

Experienced bookkeepers are hard to find and expensive to keep. Without automation a firm cannot take on more clients, because there is nobody to do the work.

Growth depends on hiring that is not happening

How to start

First a process analysis. Then a project that pays back.

I do not sell a ready-made package. First I see how your firm works, then I build what pays back fastest.

  1. Step 1

    Process analysis

    Over two meetings I go through how documents reach your firm and who handles them. After that you get a written plan.

    • The channels invoices arrive through: email, WhatsApp, e-invoice, paper
    • The software you use and where data is retyped by hand
    • 3 to 5 automations, with estimated savings and build cost
    • The plan is yours even if we stop there
    How the process analysis works

  2. Step 2

    Project

    I build what the plan shows is worth it. For accounting firms that is usually the entry of incoming invoices.

    Indicative, for a firm with 30 clients

    5,500 EUR

    Price on 10 Sep 2026: 5,500 EUR

    • Reading incoming invoices and e-invoices (CIUS-HR)
    • Classification against your chart of accounts
    • You confirm each suggestion before it is booked
    • Entry into Minimax, Pantheon or Synesis
    • Training for the team and 30 days of support

    Delivered in four to six weeks. The exact scope and amount are in the plan.

Common questions

The questions that keep coming up.

The Zakon o fiskalizaciji 2.0 (Croatia's Fiscalisation Act) made issuing and receiving e-invoices mandatory for all B2B transactions from 1 January 2026, under the CIUS-HR scheme. In practice every incoming invoice your clients receive arrives as structured XML through FINA Moj-eRačun (the state e-invoicing exchange), not as a PDF or a photo. I set up an AI that reads that XML and classifies it against your chart of accounts automatically, which removes 70 to 85 per cent of the manual work. Without automation, the workload grows with the e-invoice volume.
I work directly with Minimax (API), Pantheon (REST and files), Synesis and Luceed (files and custom). If your software has no API, I use its import format (CSV or XML templates). In the process analysis we establish which software you run and whether a custom integration is needed, and I include all of it in the cost estimate up front. No surprises.
A typical firm with 30 clients processes around 1,500 invoices a month. At eight minutes per invoice and a labour cost of 12 EUR an hour, the hidden cost is about 30,000 EUR a year. The AI automation gives back roughly 22,500 EUR a year (calculated at 75 per cent efficiency). A project of around 5,500 EUR (price on 10 Sep 2026: 5,500 EUR) pays back in about three months. The exact scope and amount for your firm are in the plan after the process analysis.
The whole infrastructure sits in the EU region (Frankfurt). Vercel EU, a Neon EU database, OCR through Mistral EU or Azure Document Intelligence EU. No US option. I sign a data processing agreement: your firm remains the controller, I am the processor. Every action is logged, with 11-year retention as Croatian accounting law requires.
Most documents go through Mistral OCR. Hard cases (handwriting, creased paper, poor light) fall back to Google Document AI. Anything the system is unsure about goes into a manual review queue. You validate those in a couple of seconds and the system learns from it, so next time the same supplier passes automatically. In the first 30 days, realistically 5 to 15 per cent of documents need a human. After 90 days it falls to 2 to 5 per cent.
