Contact us
Do I need to install anything?
No. Księgowskaz runs in your browser, and there's a mobile app for iOS and Android. Only the counter POS needs a desktop app.
How do I start keeping my books?
After signing up, add your company by tax ID and choose a tax scheme — the revenue ledger, the lump-sum scheme, or full accounting run by your office. The setup wizard walks you through the rest.
How do I turn on KSeF?
KSeF is available as an add-on (included in Business). Enable it in Settings → KSeF and authorize your account.
Can I import data from another program?
Yes — import contacts, products and documents from a CSV file. Our team will help you migrate for free.
How do I add my accounting office?
In Settings → Accounting office, send an invitation to the office's email address. The office then works in its own panel on the same data.
How do I export data for my accountant?
In Reports, choose a period and export to PDF, CSV, a JPK file or straight into Comarch Optima.
