OVERVIEW
Duqm, on Oman's Al Wusta coast, is home to the Special Economic Zone at Duqm (SEZAD), the Duqm Refinery, a commercial port, a dry dock and a growing base of industrial, logistics and construction companies. Many businesses here work on large projects with international partners.
Billing in Duqm is often project-based: construction and engineering contracts, industrial services, equipment rental and port-related charges. We map these to PINT OM with the right references and VAT treatment, and connect your ERP to an accredited service provider, with remote work and on-site visits planned around your project.
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.
Webtel supports businesses in Duqm remotely, with on-site visits where they help, such as workshops and go-live. We map your data to PINT OM, connect your systems to an accredited service provider and test real invoices, so you are ready on your phase date.
CAPABILITIES
Contractors and engineering firms on major projects.
Refinery, petrochemical and industrial companies.
Port, dry dock, shipping and logistics businesses.
Companies operating in the Special Economic Zone.
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
Milestones, progress claims and variations all create invoices.
02
Transactions in the economic zone need careful review.
03
Partners and head offices may be outside Oman.
04
Support needs to work well at a distance.
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.

Businesses with annual supplies above OMR 5 million go live on 1 April 2027 and other VAT-registered businesses on 1 October 2027. We confirm your phase during the assessment.
