How InvoiceHub helps today
InvoiceHub validates the EN 16931 core rules for Peppol UBL invoices and generates conformant UBL, echoing back the document’s declared profile honestly rather than asserting conformance to a Peppol-specific rule pack we have not tested. On-network transmission is not part of this product — InvoiceHub focuses on producing a valid document upstream of any Access Point you already use.
