Mandate Overview
The mandate
Bulgaria mandates B2G e-invoicing through the central Centralised Automated Information System for E-Invoicing (CAIS) and is preparing a phased B2B e-invoicing and SAF-T reporting reform led by the National Revenue Agency (NRA). Public consultation in 2024-2025 confirmed UBL 2.1 and Peppol BIS as the structured backbone, with first-wave large-taxpayer SAF-T reporting starting January 1, 2026 and broader B2B structured invoicing rolling out alongside the EU ViDA timeline.
