Proof, not promises

This is how Bookeper answers

One question, answered by the running system: rates from the tax engine, the legal basis, and the KIS rulings that back it.

a real answer from the systemPKD 62.01.Z

Which flat-rate (ryczałt) tax rate applies to a programmer, PKD 62.01?

Usually 12% — but the PKWiU code of the service decides, not the PKD 62.01.Z code alone.

Programming to order is PKWiU 62.01.1. Technical support and other IT services carry a lower rate, but only if that is what you actually provide.

PKWiUServiceRate
62.01.1Programming, software design and testing12%
62.01.2Software originals12%
62.02.20Software consulting12%
62.02.30IT technical support8.5%
62.09Other IT services (excluding software installation)8.5%
ex 62.09.20Software installation12%

Careful with 8.5% for programming

Applicants asked for the lower rate for PKWiU 62.01.11 services. The Director of KIS held that position incorrect:

Source: the Bookeper tax engine's rate table (art. 12(1) of the Polish flat-rate tax act) and the corpus of KIS individual rulings. A ruling binds only its applicant.

What does the traditional process really cost you?

Compare the traditional accounting process with Bookeper AI automation

Today — the manual process:

  • invoice scans by email → hours waiting for an answer
  • tax IDs and amounts retyped from PDFs by hand
  • paperwork drifting between email, Excel and desktop software
  • a simple tax question takes days, not minutes

With Bookeper AI — declaration prep:

  • upload an invoice → lump-sum tax rate with its legal basis
  • 585+ PKWiU mappings = zero guessing
  • ZUS DRA and SAF-T ready for your approval
  • a question = an answer, not days of waiting
  • prepare declarations at your own pace
Why not plain software, and why not ChatGPT

AI for conversation. Engines for calculations.

Traditional software calculates correctly but needs manual work at every step. ChatGPT answers fast but guesses — no validators, no connections to the authorities. Bookeper combines both.

How approval works

Four steps: Bookeper calculates, cites the legal basis, you approve, and the declaration is ready for you to file. After you approve, you file it yourself in e-Deklaracje or ZUS PUE. If validation finds an error, you see the error and the reason.

  1. The agent calculates

    Deterministic calculators, not guesswork.

  2. Statute citation

    Every amount comes with a legal basis you can check.

  3. You approve

    The approval is yours — Bookeper never approves for you.

  4. Ready for your approval

    Reviewed draft ready to download; you file it yourself in e-Deklaracje or ZUS PUE.

  5. And if validation finds an error?

    You see the validation error and its reason — you fix it and approve again.
