One system, not seven
Sales, purchases, the books, payroll, inventory, and assets share one set of records. A figure on the dashboard traces back to the document that produced it, because it is the same document.

Save the draft and choose where it goes: production or, for this demo, the test sandbox.
Now issue it! Butterpie builds the structured e-invoice KSeF expects and sends it off for you.
Here's the KSeF screen. Status: Accepted, and there's the KSeF number!
Open it: the status, the KSeF number and the UPO receipt, all kept on file.

Then check it against the ministry's published schema. Green light: the structure checks out.
Open the VAT-7 return: output VAT, input VAT and the amount due, every figure straight from the books.
Download the file and submit it with the ministry's own software or through your accountant. Then record the UPO receipt back in Butterpie.

A new customer? Let's add them. It only takes seconds!
A short code, the company name and the Polish tax ID, the NIP. Butterpie verifies its check digit, so typos get caught before they reach an invoice.
Then the address: street, number, postal code and city.
Set their payment terms once: bank transfer, fourteen days.
Save, and there they are, right in your list of counterparties.
Their page will list every document you exchange with them.
Now put them to work: pick them on a new invoice, and the payment method and due date fill in automatically.
Set it once, use it everywhere. Try the Butterpie demo!
Dashboards, and the detail behind every tile Length
From the overview to a tile, and from the tile to its report: range, grouping, comparison, filters and downloads.

The month closes without a scramble
Registers, returns, and filings are generated from what you already recorded. Nothing is re-typed between programs, so nothing drifts between them.
Built for Polish rules, not adapted to them
KPiR, ryczałt, or full books. VAT, JPK_V7, PIT, CIT, ZUS, and KSeF. The statutory shape is the product's shape, not a plugin on top of a product built for other rules.

An add-on, not a plan: a single top-up of AI credits for your workspace, valid for 12 months from purchase. Credits are spent as you use the assistant, nothing renews on its own, and you can spend them on AI-capable seats.
Prices are quoted in Polish złoty (PLN) — the same amount in every country.
The price shown is the amount charged: applicable tax in your country is already included, not added at the end. Card details go straight to our payment provider and never reach us.
Built to be checked, not trusted
Security claims are easy to write. These are the ones we can show you.
Your data is fenced at the database, not in the code
Separation between organizations is enforced by the database itself, underneath the application — so a mistake in our own code cannot read across organizations.
Support cannot look without your consent
A support engineer needs a time-boxed grant that you approve, and every entry is recorded on your own support access log.
The audit trail cannot be edited
Records are hash-chained and append-only; the chain can be verified from inside the app.
Questions we are asked
If yours is not here, write to us — a person answers.
Can I try it before paying?
Yes. The demo is a complete worked company with real books, open to anyone, with no sign-up and no card. It is read-only, so you can click through everything without changing anything.
Which set of books can I keep?
KPiR, ryczałt, or full double-entry books. The choice drives which registers, returns, and filings the product keeps for you, so you are not maintaining a book the tax office does not want.
Does it handle KSeF?
Yes, inbound and outbound. A KSeF number is recorded against the invoice it belongs to, so the register and the national system name the same document.
How are the filings produced?
From the registers you already keep. JPK_V7, the VAT returns, PIT, CIT, and ZUS are generated from your own documents rather than re-entered, which is what stops two systems disagreeing about one month.
Who can see my data?
Separation between organizations is enforced by the database itself rather than by application code, so a mistake in the code cannot read across organizations. A support engineer needs a time-boxed grant that you approve, and every entry appears in your own support access log.
What happens if I want to leave?
A full export in an open format, and erasure that reaches backups on a published schedule. Both are yours to run; neither requires asking us.
How is tax on the subscription handled?
The amount shown on the pricing page is the amount charged — the tax due in your country is already included, not added at the end. The subscription is sold through a payment provider that acts as seller of record and handles the tax; your card details go to them and never reach us.
