Infrastructure & Accreditation

Not middleware — a certified Peppol operator in production.

Sahalah runs on a Peppol G3-certified Dual Access Point and SMP operator network, pre-approved by the Oman Tax Authority in January 2026 and listed on the Fawtara E-Invoicing Project preliminary service-provider panel. Every invoice travels through a 5-layer validation pipeline on AWS-native, GCC-resident infrastructure — no third-party broker in the network path.
