Why Fiskora
For one-person businesses with clients in other countries
KSeF, start to finish
Fiskora sends each invoice to KSeF. KSeF gives the invoice a KSeF number and an official receipt (UPO). Invoices that you receive come into Fiskora automatically. To correct an error, you issue a correction invoice, as the law requires.
Your accountant is included
Give your accountant a free read-only login. Your accountant can see and download all invoices. You do not have to send files every month.
How it works
From sign-up to your first KSeF invoice

What's included
