efsta helps companies comply with country-specific e-invoicing requirements. The solution currently covers Germany, Italy, Poland, and Belgium, among others. Additional countries will be added gradually in accordance with local regulatory requirements.
Starting in September 2026, France will introduce mandatory e-invoicing (B2B) and e-reporting (B2C/international B2B).
efsta covers both through a single integration: The Fiscal Middleware (EFR), in partnership with Iopole as an approved “Plateforme Agréée,” handles e-invoicing, e-reporting, and digital merchant onboarding. Existing partners can activate the solution directly on their existing integration.
As of January 1, 2026, electronic invoicing is mandatory for all B2B transactions. Implementation is based on the Peppol BIS 3.0 standard and enables structured, automated processing of e-invoices.
efsta is a certified Peppol Access Point Provider and is fully prepared to meet the requirements. Companies can connect their systems directly to the Peppol network, send e-invoices in compliance with regulations, and benefit from scalable, audit-proof operations.

The use of e-invoices has been mandatory since January 1, 2025. Businesses must be able to receive and process e-invoices, while transitional provisions apply to the issuance of e-invoices until the end of 2027.
The standard format is XRechnung, which enables structured and automated processing. These requirements are increasingly affecting the B2B sector as well and are driving the standardization of digital invoicing processes.
Electronic invoicing has been mandatory in the B2B sector since 2019. Processing takes place via the SDI system (Sistema di Interscambio) and is based on structured data formats to ensure automated, compliant processing.
efsta supports integration with the SDI system and enables seamless connectivity with existing POS, ERP, and back-office systems.
As of February 1, 2026, electronic invoicing is mandatory in the B2B sector. Processing takes place via the government system KSeF (Krajowy System e-Faktur) and is based on a prescribed XML format.
Companies are required to ensure seamless integration with the KSeF API, validate invoice data, and convert it to the prescribed XML format. Additionally, the invoice status must be tracked in real time, and archiving must be ensured in accordance with Polish regulations.
