E-invoicing mandate

E-invoicing in Belgium

What businesses invoicing in Belgium need to know about structured e-invoicing, and how FreeBillGen keeps you compliant.

Belgium offers a temporary increased cost deduction (up to 120%) for 2024-2027 on the invoicing software and services used to comply, so getting e-invoicing-ready can effectively cost your business nothing after tax. The mandate is already in force - FreeBillGen produces the Peppol BIS 3.0 file you need, for free.
