Who is behind Peppol Box?
Peppol Box is the youngest product of a company that has been doing invoicing since 2008. Flexina, based in Liège, launched it in 2024 for a simple reason: many freelancers wanted Peppol, just Peppol, at a small price.

Where Peppol Box comes from
Flexina has been sending invoices over the Peppol network since 2021 inside its full business management software. In 2024 we carved that part out into a standalone product: for merchants who only needed to receive their invoices, and for part-time freelancers, micro-businesses and small structures that needed Peppol without a full commercial management package.
We also declined it as an API, for companies whose ERP was not ready for the reform or whose custom-built systems could not be adapted. When the Belgian obligation took effect in January 2026, our users had been ready for a long time.
In Belgium, B2B electronic invoicing has been mandatory since January 2026. Peppol Box uses your BCE company number as Peppol identifier, and our Belgian customers were invoicing on the network well before the deadline.
