2
Validation & Conversion
C2 validates against the UAE data dictionary and converts to standard XML if required.

Transmission & Reporting

UAE e-Invoicing FAQ
1 What is PEPPOL e-Invoicing?

The PEPPOL 5-corner model involves five key components: the issuer, the receiver, the central tax platform
(Federal Tax Authority), and their respective Accredited Service Providers (ASPs).

ASPs validate e-invoice data against the UAE data dictionary, transmit invoices through the PEPPOL network,
