KSeF for small businesses

On 1 January 2027 the PLN 10,000 monthly threshold used by the smallest businesses ends – every invoice for another company will have to be issued in KSeF, Poland’s national e-invoicing system. We choose the program, configure it and train your team.

For companies issuing a handful of invoices a month, the simplest option is often Subiekt 123 – a browser-based program with nothing to install. When you run a warehouse or need more, we recommend Subiekt nexo or Navireo. Purchase invoices downloaded from KSeF can go straight to Rachmistrz or Rewizor.

We also help with KSeF permissions, tokens and certificates, with the invoice flow between your company and your accountant, and with what to do when KSeF is down. If you use another sales system, we can connect it to KSeF through an integration.
