Mandatory electronic invoicing 2026: complete guide for SMEs

Electronic invoicing becomes mandatory in France from September 2026. Here's everything your SME needs to know and prepare. The reform timeline: Mandatory electronic invoicing rolls out in two phases in France. From 1 September 2026: mandatory receipt of electronic invoices for all VAT-liable companies. From 1 September 2027: mandatory issuance for mid-size and large companies. 1 September 2028: mandatory issuance for SMEs and micro-enterprises. What is an electronic invoice?: A PDF sent by email is NOT an electronic invoice under the reform. An electronic invoice is a structured file (Factur-X, UBL or CII format) that can be read and processed automatically. Factur-X is recommended for SMEs: a human-readable PDF with embedded machine-readable XML data. Dematerialisation platforms (PDP): Electronic invoices must transit through registered Partner Dematerialisation Platforms (PDP) or the Public Invoicing Portal (PPF). PDPs handle transmission, format validation, and reporting to tax authorities. Impact on your organisation: The reform requires reviewing: up-to-date client/supplier directory, mandatory mentions on each invoice, adapted validation workflow, 10-year legal archiving, and automated accounting reconciliation. It's also an opportunity: reduced payment delays, fewer data entry errors, real-time cash flow visibility. Action plan with Powehi: 1) Diagnostic of your current invoicing chain. 2) Choosing the right PDP. 3) ERP or invoicing software compliance (Factur-X export). 4) Flow integration and automation. 5) Team training. Recommended: start 6 months before the deadline.
