Retail companies in Poland are bracing for significant challenges as they prepare for the implementation of the National e-Invoicing System (KSeF), which is set to become mandatory for the largest enterprises by February 1, 2026. Despite this upcoming deadline, the interest in the platform is notably high among businesses, with nearly 2 million users already authenticated shortly after its introduction. This has raised concerns among retailers about potential disruptions to their supply chains as they adapt to new invoicing requirements.

The large enterprises are reported to be holding back inventory in their warehouses, primarily due to the incompatibility issues arising between the existing Electronic Data Interchange (EDI) formats and the new invoicing system. These discrepancies can complicate the automated processing of invoices, leading to increased workloads and delays in transactions. Retailers are implementing preventive measures to mitigate the impending disruptions, but the uncertainty of these system changes creates anxiety about future supply levels.

Moreover, the introduction of structured invoices presents its own set of challenges for retailers, as they must adapt their operational practices to comply with the new standards. The fear of encountering empty shelves illustrates the broader implications of these regulatory changes, which could affect not just retailers but their customers as well. As the system rolls out, the ongoing adjustments will be keenly watched by businesses and consumers alike, highlighting the critical need for effective transition strategies in the face of digital transformation in invoicing processes.
