UAE E-Invoicing:
Client Onboarding & Implementation Journey
B4B Consultancy | E-Invoicing Implementation and Compliance Support Partner
1. What is UAE E-Invoicing?
The Electronic Invoicing System is established by Ministerial Decision No. 243 of 2025 (scope) and Ministerial Decision No. 244 of 2025 (implementation), issued by the UAE Ministry of Finance.
- It applies to B2B and B2G transactions, with limited exclusions (certain financial services and airline services). B2C is excluded until further notice.
- Invoices are issued and exchanged through an Accredited Service Provider on the Peppol-based network.
- The service provider validates invoices and reports them to the Ministry of Finance and the Federal Tax Authority.
2. Why Prepare Now?
