A major reform is coming — and with it, big changes in how businesses will handle their invoicing.
The goal is clear: to simplify, secure, and modernize B2B exchanges.
While e-invoicing is already mandatory for public sector contracts, a broader reform will soon apply to all VAT-registered businesses in the coming years.
Here’s what you need to know 👇
đź“… Key Dates to Remember
According to Belgian law, January 1, 2026 marks the start of the new requirement:
→ All VAT-registered businesses will be required to issue electronic invoices for B2B transactions.
❓ Digitization ≠E-Invoicing
Going fully digital doesn’t mean you’re compliant.
A PDF invoice, even sent via email, does not qualify as a true electronic invoice under the new rules.
A true e-invoice must:
- Follow a structured format (Factur-X, UBL, CII, etc.)
- Contain machine-readable data
- Be transmitted via a certified platform
In short: Scanning or emailing a PDF is not enough. You’ll need to use a certified channel and comply with an approved format.

đź”— How will It work?
Starting in 2026, invoices will no longer be exchanged directly between supplier and client. Instead, they will flow through certified platforms using the PEPPOL network.
Each business will need to:
- Choose a PEPPOL e-invoicing service provider
- Send and/or receive e-invoices through that provider
- Ensure their tools and systems are compatible
To help ease this transition, ABCinvoice.eu is becoming a PEPPOL-certified service provider, working closely with an approved Access Point platform.
đź’¶ What About E-Reporting?
E-reporting is expected to become mandatory in Belgium by 2028.
While this requirement isn’t active yet, it’s crucial to plan ahead. Just like e-invoicing, businesses will need to send certain transaction data to the tax authorities.
The good news? ABCinvoice.eu will be ready.
Thanks to our experience with the French reform, our tool already integrates e-reporting mechanisms. So, you’ll be fully equipped when the time comes.
