Peppol and the mandate

01What is Peppol?

Peppol is a European network and set of standards for exchanging electronic business documents such as invoices. You connect through one access point and reach every registered company.

02Since when is e-invoicing mandatory in Belgium?

Since 1 January 2026 for B2B invoices between VAT-registered companies established in Belgium. The tolerance period ended on 31 March 2026.

03What are the fines?

€1,500 for a first offence, €3,000 for a second and €5,000 for every further offence when you cannot send or receive structured e-invoices.

04Is the Peppol network itself free?

There is no fee for the network as such, but you need a provider with an access point and software to create, send and receive invoices.

Using PeppolNavigator

01How do I start?

Contact us for a demo. After onboarding you register your company on Peppol from inside the app and can start sending.

02What happens if my customer is not on Peppol?

The invoice is sent by email instead, automatically. You can also download the PDF or the UBL.

03Can I make quotes and recurring invoices?

Yes. Quotes can be converted into invoices, and recurring invoices are generated on the schedule you choose.

04Which languages does the app support?

Dutch, French, English and German. PDFs and emails follow each customer’s language.

05Can I use my own invoice layout?

Choose from 37 templates, customise logo and colours, upload your own HTML template, or upload a PDF to use as the invoice.

Formats, API and data

01Which formats can I receive?

Peppol BIS 3.0 UBL invoices and credit notes, UN/CEFACT CII, NLCIUS, PINT, and the XML inside Factur-X, ZUGFeRD, XRechnung and Order-X PDFs.

No. PeppolNavigator processes electronic documents; it does not do OCR of paper or scanned invoices.

03Is there an API?

Yes, a REST API documented with OpenAPI, with a sandbox for testing.

04Can I export my data?

Yes. Export documents as PDF, UBL or both in a ZIP, reports as CSV, and incoming documents per quarter.
