Flagship service

KSeF 2.0 — we invoice in it every day. Your KSeF invoices go straight into the books.

KSeF has been mandatory in Poland since 1 February 2026 for the largest taxpayers and since 1 April 2026 for the rest. Profais issues its own invoices through KSeF and fetches clients' invoices from KSeF for posting. We do not issue invoices on behalf of clients — we help you set up permissions and keep the document flow tidy.

Day-to-day support

Corrections, offline mode during outages, changes on the Ministry of Finance side — we keep track of them for you.
