How does Oman's e-invoicing model differ from Saudi Arabia's and the UAE's?

Although Oman, Saudi Arabia, and the UAE are all implementing structured electronic invoicing, their models are not identical.

Oman uses a Five-Corner Model based on Peppol standards. The model includes the supplier, supplier service provider, buyer service provider, buyer, and the Oman Tax Authority. The country's invoice specifications are based on PINT OM.

Saudi Arabia uses the ZATCA Fatoora framework. Its implementation is divided into Phase 1 and Phase 2. Phase 1 focuses on electronic invoice generation and storage, while Phase 2 requires integration with ZATCA's Fatoora platform and is being introduced through successive waves.

The UAE is also adopting a Peppol-based model, but its framework uses a decentralized exchange and reporting approach involving Accredited Service Providers. The UAE's implementation has its own local specifications, requirements, and rollout timelines.

The key difference for businesses operating across these markets is that Peppol does not mean identical compliance. Even where countries use the same underlying interoperability framework, businesses still need to meet each country's specific invoice formats, tax rules, reporting requirements, and implementation timelines.
