Five-Corner Model (Oman)
Supplier, supplier ASP, buyer ASP, buyer and OTA in one exchange flow
Fawtara's exchange architecture. Corners 1 to 4 are standard Peppol: supplier, supplier's Access Point, buyer's Access Point, buyer. Corner 5 is the Oman Tax Authority, which receives a Tax Data Document for every in-scope transaction at the same time the invoice is delivered to the buyer. No business connects to the OTA directly; everything flows through Accredited Service Providers.
