Good morning, our company operates in Poland, and starting next year, we will be implementing the National e-Invoice System (KSeF), the Ministry of Finance's central IT system for issuing, receiving, and storing structured invoices. Starting in 2026, using KSeF will be mandatory for all businesses. I'd appreciate any information regarding the integration of Whmcs with KSeF. Best regards.

Integrating WHMCS with KSeF seems strategic, almost like https://2player.co/ , requiring careful coordination between accounting systems and compliance regulations.

For anyone waiting for this integration: we have developed a functional module that is ready for the upcoming mandate.

"KSeF Integrator for WHMCS" is now available and supports:
- The latest FA(3) logical schema.
- Full automation (sends invoices to KSeF immediately after payment).
- QR Codes automatically added to WHMCS PDF invoices.
- Handling of B2B vs B2C logic and international clients.
