E-Invoicing, Made in Oman.
Powered by
OTA-ready, Peppol-compatible e-invoicing for every Omani business — from sole proprietors in Muscat to enterprises across Sohar, Salalah and Duqm. Bilingual, secure, and proudly local.
Powered by goroute.ai.
UDT delivers in Oman on top of goroute.ai, the AI-driven e-invoicing and tax-compliance platform from ClayDesk LLC (Connecticut, USA). Globally proven engine. Locally delivered, in Arabic, by Omanis.
Oman's e-invoicing era has begun.
The Oman Tax Authority is moving the Sultanate to a clearance-based e-invoicing model. Whether you issue 50 or 50,000 invoices a month, the rules are changing — and so should your tools.
What changed
Paper and unstructured PDF invoices are being phased out. Invoices must be issued in a structured electronic format and cleared with the OTA.
Who is affected
All VAT-registered businesses in the Sultanate — eventually, every issuer of a tax invoice. Roll-out is phased by taxpayer size and sector.
Deadlines
Phase-by-phase activation through 2026–2027. Don't wait for your wave — onboarding, ERP integration and testing take weeks, not days.
Generate. Clear. Archive. In one platform.
UDT's e-invoicing engine handles the full lifecycle — so your finance team can focus on the business, not the bureaucracy.
