Oman E-Invoicing (Fawtara)
Prepare Your Business for Oman’s Fawtara E-Invoicing Mandate
The Oman Tax Authority is moving the Sultanate to mandatory structured electronic invoicing through its national programme, Fawtara. Under Decision No. 189/2026, taxable persons with annual supplies above OMR 5 million must comply from 1 April 2027, and those at or below that threshold from 1 October 2027, following a pilot that began with an initial group of large taxpayers in August 2026.
Fawtara is not a monthly reporting exercise added on at period close. It changes how every invoice is issued: documents must be created in a structured format, validated against the Tax Authority’s rules, and transmitted through an accredited service provider before they reach your customer. Dynamics Center helps businesses in Oman meet these requirements inside the ERP they already use — Microsoft Dynamics 365 Business Central or Dynamics 365 Finance and Supply Chain Management.

What Fawtara Requires
Fawtara is built on the Peppol framework. The Oman Tax Authority was approved as a Peppol Authority in January 2026 and adopted a five-corner exchange model, in which invoices pass from the supplier to the supplier’s accredited service provider, on to the buyer’s service provider and the buyer, with reporting to the Tax Authority.
In practice, that means four things change for a finance team in Oman.
A structured invoice format
Invoices must be issued as PINT OM, the Oman specification built on UBL 2.1 XML, with a PDF/A-3 document carrying the structured data. A PDF emailed to a customer is no longer an invoice in the regulator’s eyes.
Delivery through an accredited service provider
Documents are transmitted through a service provider accredited by the Oman Tax Authority, which validates the invoice and routes it over the Peppol network. Your ERP has to speak that provider’s API.
Validation your data has to survive
Invoices are checked against schema, business rules and code lists. A customer without a tax registration number, or a unit of measure outside the approved code list, is enough to cause a rejection.
Records you can produce on demand
Invoice records must be retained electronically for the statutory period — ten years in general, longer for real estate records — and be retrievable for audit.

Choose Your Dynamics 365 Platform
Dynamics Center offers Fawtara compliance for both Microsoft ERP platforms. The compliance logic, terminology and reporting are consistent across the two, which matters for groups running both in the same region.

- January 2026 — The Oman Tax Authority is approved as a Peppol Authority, formally adopting the Peppol framework for Fawtara.
- August 2026 — The pilot begins with an initial group of large taxpayers.
- 1 April 2027 — Mandatory for taxable persons with annual supplies above OMR 5 million.
- 1 October 2027 — Mandatory for taxable persons with annual supplies at or below OMR 5 million.
A later phase covering government entities is expected, and the Tax Authority has not yet confirmed its date. Businesses should confirm their own phase and obligations against the latest guidance issued by the Oman Tax Authority.
Why Start Before Your Phase Date
Non-compliance carries financial penalties under the VAT law, up to and including suspension for serious or repeated breaches. But the practical risk for most businesses is not the penalty — it is the data.
The most common causes of invoice rejection are mundane: a customer record with no tax registration number, a unit of measure that was never mapped to the approved code list, a VAT category code left blank on a single line. Individually they take minutes to fix. Across a live customer master of several hundred accounts, they take weeks, and they surface only when invoices start failing.
Starting early converts the deadline from an event into a routine. A readiness assessment identifies the gaps while there is still time to close them in the ordinary course of business, rather than in the week before go-live.
How Dynamics Center Helps
Fawtara Readiness Assessment
We review your invoicing processes, ERP environment and master data against the Fawtara requirements and give you a prioritised list of what needs to change, with effort estimates.
Solution Implementation
We install and configure the Oman e-invoicing solution in your Dynamics 365 environment, connect it to your chosen accredited service provider, and align it to your document types and business processes.
Master Data Remediation
We identify customers, items and units of measure that would fail validation, and work with your team to correct them before they cause rejections.
End-to-End Testing
We run full invoice, credit note and debit note cycles in the service provider’s sandbox, verifying validation, transmission and clearance before anything reaches production.
Go-Live and Cutover
Our team supports the production switchover so day-one invoicing continues without interruption.
Ongoing Support and Regulatory Updates
Fawtara is a phased programme and the specification will evolve. We keep your solution current and support your team as the rules change.
Why Choose Dynamics Center?
Dynamics Center is a certified Microsoft partner specialising in Dynamics 365, with e-invoicing solutions already published on Microsoft AppSource for the UAE and Saudi Arabia. We have taken businesses through the ZATCA rollout in Saudi Arabia and the UAE e-invoicing programme, and that experience shapes how we approach Oman: assess the data first, test the full document lifecycle, and go live with no surprises.
We do not apply a single template to every client. We assess your environment, understand how your finance team actually works, and configure a solution that fits your processes rather than forcing your processes to fit the software.
