UU Invoice Portal (eConnect)
Due to the transition to e-invoicing as of 1 January 2026 for all suppliers in Europe, we have developed the UU Invoice Portal in collaboration with eConnect so that suppliers who are not (yet) connected to the Peppol network or cannot link their software can generate (or XML upload) and send e-invoices free of charge.
Instructions
Below you will find a visual representation (click on the image to enlarge it) with instructions for filling in the invoice details. Below that, you can download a document that takes you step-by-step through the process of generating an e-invoice or uploading an XML file. At the moment only available in Dutch, we are working on the English version.
