You issue the invoice once. Working out the month's tax, filing the declaration with the tax office and bringing back the official proof it was accepted — that part of the deal is already ours.
Overview
14 days with every feature unlocked, no card. After that your account moves to the free plan — not to a paid one.
Pick your legal form and you will see both columns of the deal. We say this up front, before you open an account — not after.
On the ryczałt we run the whole month: the invoice, the contributions worked out, a declaration already sitting at the tax office with its UPO. On the tax scale and the flat tax, invoicing and the whole of VAT already work — the ledger itself does not yet.
Ryczałt — the whole month · tax scale and flat tax — invoices, KSeF and VAT
Create an accountSending an invoice to KSeF is the price of entry today — even the Ministry's free app does it. The difference shows when the gateway stops answering. You turn the automation on once, deliberately; after that we see to it that the document gets through, comes back with its number, and keeps the official proof of receipt beside it.
The contractor comes from GUS by NIP; the VAT white list is checked and saved with the date.
The moment you issue it, if the automation is on.
Straight back onto the document. And if it is rejected, we say so plainly.
The official confirmation of receipt (UPO) stays with the invoice, its signature verified with the Ministry.
We do not cap KSeF sends — not even on the free plan.
The month is ending and your inbox holds a stack of invoices as PDFs and photos — from suppliers abroad, scanned off paper, the ones that never came through KSeF. Drag the whole batch onto your invoice list, see one price for all of it and click once. The reading (OCR) runs in the background: Biurko AI fills in ordinary invoice forms, and you check them one by one and save each yourself.
How a batch is read in the app
Every plan comes with AI credits, the free one too — a fresh allowance each month.
The contractor's VAT status, the account you pay into against the white list, the EU VAT number in VIES and the NIP against the Polish sanctions list — Biurko checks them itself, on the document they concern. The result warns and never locks anything, and the register's answer stays on the document with its date.
Whether the contractor is an active VAT payer, and whether the account on the invoice is assigned to their NIP — the account as of the day the transfer was ordered. Every answer carries the request identifier the register gave it.
Whether the EU VAT number of a contractor from another member state is valid. An invalid buyer number on a 0 % supply shows up in the panel together with what it means.
The contractor's NIP compared with the Polish sanctions list. A hit is shown as a “possible match” to check, not a conclusion — and only your company sees it.

The account is not on the list and the transaction is above the statutory threshold? The panel names the consequences and the provision, tells you how to avoid them and shows the deadline for the ZAW-NR notice. You record the day you filed it — Biurko sends neither the notice nor the transfer for you.
Checks work on every plan, the free one included.
Your VAT registers build themselves out of your invoices, with nothing retyped. That is where the tax comes from, and the declaration, and the official proof it was accepted.
October 2026
SettledA contractor in Berlin or Kyiv gets the document in their own language — out of the same invoice you are issuing anyway. Ten templates, ten document languages.
One thing, plainly: edit the set itself and every invoice sitting on it is redrawn — which is why the look you use for exports belongs in a set of its own.
None of this touches the FA(3) XML: the template, the colour and the language change nothing in what goes to KSeF.

A huge title, the total on colour
You connect an assistant to your company over the open MCP protocol — it gets more than a hundred tools, the same operations you click yourself. It works on your documents themselves, not on a copy.

You authorize once through OAuth, with no keys to copy across — and the assistant connects on the paid plans, not the free one.

The contract, the acceptance protocol and the delivery proof sit with the invoice they belong to — you drag them onto the document.
Only the invoice XML reaches KSeF — the contract and the protocol stay in Biurko.
Today Biurko closes the month for a firm on the ryczałt. Each further step widens that promise — and we give no dates: a step reaches this page only once you can click it.

Leave your email address and step straight in — no card, no password. Give us your NIP and the demo stands on your own company from the GUS registry, not a made-up one; no Polish company of your own — leave the field empty and we'll open it on an example micro-company. Inside, a work history already in place: invoices, registers, the tax worked out, filings and KSeF statuses.
You're in as soon as you send
We use your name, your email address and — if you give it — your NIP only to open a demo account for you, let you in and write to you about that demo. They aren't added to a newsletter or shared with anyone outside Biurko. We delete the demo account, along with this data, automatically once the demo ends. The exact date is in the email we send you. Full details are in the Privacy Policy.
You can object to the processing of your data and ask us to delete it at any time — write to contact@itcompass.io.
What belongs on an invoice, how KSeF works in practice, and what the ryczałt and the JPK files ask of you.
Debts at ZUS and the Polish tax office can be spread into instalments or deferred, replacing standard late-payment interest with a lower prolongation fee. Neither authority will offer an agreement automatically, so the taxpayer must file a well-justified application. Submitting a request does not instantly halt enforcement, making early preparation essential.
Foreign sales revenue in Poland falls under four distinct VAT classifications, while income tax follows standard PIT rules. B2B invoices for foreign clients enter KSeF starting 1 April 2026. Securing 0% VAT or reverse charge treatment depends on valid buyer IDs and timely submission of shipping proofs.
An active sole proprietorship in Poland generally requires filing an annual tax return even if no sales occurred during the year. Depending on your tax structure, a zero PIT-36, PIT-36L or PIT-28 for 2026 must be submitted by 30 April 2027.
