OVERVIEW
Construction billing rarely looks like a simple sales invoice. Contractors invoice against payment certificates, hold back retention, bill variations and pass on materials, and they often work with consultants, subcontractors and government clients at the same time. All of these invoices fall under Fawtara.
We work through your contract types and billing cycle, from interim payment applications to final accounts, and map each one to a PINT OM e-invoice with the correct references. The goal is that your quantity surveyors and accountants keep their process, while the e-invoice is produced automatically at the end of it.
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. Note that government entities are expected to follow later, so contractors billing ministries should confirm the requirements that apply to those invoices.
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
Interim invoices based on payment certificates are issued as e-invoices.
Retention held and released is shown clearly and consistently.
Approved variations and claims are invoiced with clear references.
Your own subcontractors' invoices arrive in structured form too.
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
Each interim invoice must show the right amount for the period, not the running total.
02
Deductions and recoveries must be treated consistently on every invoice.
03
Invoices need consistent project, contract and certificate references.
04
JVs and consortia may need separate VAT and e-invoicing setups.
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.

WHY WEBTEL
FAQS
Retention is shown consistently according to how it is treated for VAT in your contracts. We review your contract terms and agree the treatment before configuring anything.
Government entities are expected to come into Fawtara later. We help you plan for both private and government clients so you are not caught out.
Yes, if it produces the invoice. Otherwise we connect the accounting system where invoices are finalised.
It depends on your annual supplies. Businesses above OMR 5 million go live on 1 April 2027 and all other VAT-registered businesses on 1 October 2027. We confirm your phase during the assessment.
No. Fawtara uses a five-corner model, so e-invoices are exchanged through an accredited service provider. Your system connects to the provider, which delivers the invoice and passes the tax data to the OTA.
Usually not. Most ERP and accounting systems can be connected to an accredited service provider. We check your system and recommend the simplest route.
