Peppol e-invoicing inside your construction software
With Bouwflow you send your sales invoices automatically over the Peppol network, and your suppliers' purchase invoices come straight back into Bouwflow. Peppol e-invoicing has been mandatory for B2B in Belgium since 1 January 2026. You handle it without a separate invoicing portal, and nobody has to retype anything.
What is Peppol?
Peppol is an international network for exchanging invoices and other business documents securely and automatically between companies and governments. Instead of emailing a PDF, you send your invoice as a standardised file that lands directly in the recipient's accounting system.
For public tenders, e-invoicing via Peppol has been required for a while. Since 1 January 2026 that obligation applies to all B2B invoices in Belgium; private individuals are out of scope. To use Peppol, your company is registered on a Peppol Access Point, the official gateway to the network, and both you and your customer need to be registered on it.
