KSeF in Microsoft Dynamics — full automation of e-invoicing with Retcon

What is KSeF and why is it so important?

National e-Invoice System (KSeF) is a platform of the Ministry of Finance for issuing, receiving and archiving invoices in electronic format (XML). From 2026, the use of KSeF will be mandatory for all companies in Poland.
This is a milestone in the digitalization of settlements — it reduces paper document flow, minimizes errors and increases the transparency of financial data.

To fully exploit the potential of the National e-Invoice System (KSeF), companies using Microsoft Dynamics need a secure and seamless integration with the ERP system.
