Sources and editorial review policy.

Primary sources

UAE: the Ministry of Finance e-invoicing portal and current decisions. Oman: the Tax Authority Fawtara portal, implementation checking service and current notifications. We prefer authority material over third-party summaries.

Review and corrections

Last editorial source review: 26 October 2026. Recheck date-dependent claims before active campaigns. Where sources conflict, show the uncertainty and confirm applicability rather than publishing a guessed deadline.

Product and partnership claims

Demonstrate deployed functionality. Do not turn a roadmap into a live connector, or a proposed partnership into accreditation. Prices, service levels and legal provider responsibilities require documented confirmation.
