Stijn Heuninck, CEO of Cashfeed, clarifies: “Many businesses still have a significant catch-up to make. However, Peppol is the ideal way to process the flow of incoming invoices, for example. At Cashfeed, companies can categorize and handle a large bulk of invoices in one go through that network. The mandatory transition can therefore also be an opportunity to digitize and streamline the entire administration.”

Methodology

Cashfeed collected public data from all Belgian businesses from the company database of scale-up Bizzy on 01/10/2025 and checked whether they were already connected to Peppol. This was done through validation on www.peppolcheck.be. The companies were categorized by sector according to the NACE-BEL codes. Businesses that are only connected via the digital counter Hermes-SMP were not counted, as their connection to Peppol terminates on December 31, 2025.
