FAQ

Everything you need
to know about Fawtara

Who must comply with Fawtara, and when?

The Oman Tax Authority is rolling Fawtara out in phases. A pilot with about 100 large taxpayers started in August 2026. It becomes mandatory on 1 April 2027 for businesses with annual supplies above OMR 5 million, and on 1 October 2027 for businesses with supplies up to OMR 5 million. The date for government entities is still to be announced.

Do I need to replace my ERP or accounting system?

No. AMAN Invoice connects to the system you already use, whether it's an ERP, accounting software or an in-house app. Your team keeps invoicing the same way, and we handle formatting, delivery and reporting in the background.

Does Oman use the Peppol network?

Yes. Fawtara follows the Peppol five-corner model. Your invoice travels from your system through your accredited provider to your buyer's provider and on to your buyer, while tax data is reported to the OTA as the fifth corner.

What counts as a valid e-invoice?

A structured invoice in the PINT-OM format, issued through an OTA-accredited service provider. A PDF, a scanned image or an email attachment on its own doesn't count as an e-invoice under Fawtara.

Where is my invoice data stored?

In Oman. Production, disaster recovery, backups and encryption keys are all hosted in the Sultanate, and every invoice is archived for 10 years so it's ready for an audit.

How long does it take to go live?

It depends on your system and invoice volume. Every project starts with a free consultation and demo: you see the platform live, we review your systems and invoice types, and you get a clear plan and go-live date. We then connect and test your real invoices end to end before switching you on.
