OVERVIEW
Oil and gas operators, service companies and suppliers are among the largest businesses in Oman, which places many of them in the first Fawtara phase. Their billing covers hydrocarbon sales, long-term service contracts, rentals, day rates and joint venture cost recharges, usually from large ERP systems such as SAP or Oracle.
Certain supplies in the sector, such as crude oil, oil derivatives and natural gas, may be zero-rated under Omani VAT law, while most services are standard-rated. We map each contract type and billing pattern to the right tax category and PINT OM structure, and connect your ERP using standard interfaces.
Under Ministerial Decision 189/2026, VAT-registered businesses with annual supplies above OMR 5 million go live on 1 April 2027 and all other VAT-registered businesses on 1 October 2027, after a pilot with around 100 selected companies that started in August 2026. Both B2B and B2C invoices are in scope, and e-invoices must be archived electronically for ten years. For most operators and major service providers, this means planning now for the April 2027 phase.
Webtel works with your finance and IT teams from the first review of your invoices to the first weeks after go-live. We map your data to PINT OM, connect your system to an accredited service provider and test real scenarios, so your team keeps invoicing the way it does today while every invoice meets Fawtara requirements.
CAPABILITIES
Day rates, milestones and service tickets are invoiced from your ERP.
Cost recharges between partners carry the right references.
Qualifying supplies are classified with the correct tax category.
SAP, Oracle and other enterprise systems are connected via standard interfaces.
COMMON CHALLENGES
These are the issues we see most often. Each one is planned for from the start, so it does not surface in the week before go-live.
01
Changes must fit existing transport, testing and release processes.
02
Invoices draw on contracts, service entries and approvals.
03
Zero-rated and standard-rated supplies may appear in the same group.
04
Every e-invoice must be traceable back to the contract and approvals.
THE FAWTARA MODEL
Fawtara, the Oman Tax Authority's e-invoicing programme, uses a Peppol-based five-corner model. Invoices are issued in the PINT OM format and travel through an accredited service provider, which delivers them to the buyer and passes the tax data to the OTA. Invoices cannot be sent from an ERP directly to the OTA.
Step 1
In your ERP, accounting or billing system.
Step 2
Checked against PINT OM and Omani VAT rules.
Step 3
Your accredited service provider exchanges it over Peppol.
Step 4
Delivered to the buyer's own service provider and system.
Step 5
Tax data reaches the Oman Tax Authority through Fawtara.
