Oman’s e-invoicing 5 corner model
Oman is expected to implement a 5-corner model, where e invoices move through accredited service providers rather than being exchanged directly between buyer and supplier. This approach supports controlled exchange, consistent standards, and more reliable compliance processes.
The 5 corner model how invoices are expected to move
Corner 1 - Supplier
The supplier creates the invoice in an approved system (ERP or billing solution).
Corner 2- Supplier Service Provider
The invoice is sent to the supplier’s accredited service provider for exchange and compliance handling.
Corner 3 - Network exchange
The service provider transmits the invoice through the interoperable network to the buyer side.
Corner 4 - Buyer Service Provider
The buyer’s service provider receives and delivers the invoice into the buyer’s environment.
Corner 5 - Buyer and authority enablement
The buyer receives the structured invoice for processing, while required compliance data and controls are supported through the accredited provider model.

Oman e Invoicing (Fawtara) at a glance
Oman’s e invoicing program (Fawtara) is moving forward to replace paper and PDF invoices with structured e invoices exchanged through accredited service providers under a 5 corner model. With the first wave expected from August 2026 and phased expansion through 2028, early preparation is key.
As a certified Peppol Access Point, Melasoft helps you make your ERP and invoicing flow Oman ready with integration, testing, and audit ready controls.
Who will be affected?
The rollout is expected to begin with large companies and mid-sized businesses as early adopters. As the program expands, all VAT registered businesses in Oman are expected to transition to e invoicing.
This typically includes:
-
Retail and wholesale businesses
-
Service providers and professional firms
-
Industrial and manufacturing companies
-
Public sector organisations that process VAT related invoices
How to Prepare for E-Invoicing in Oman
Register and confirm your scope
Review your VAT status and confirm whether your entity is included in the first wave or a later phase of the rollout. If registration or onboarding steps are required by the Oman Tax Authority, ensure they are completed early to avoid delays.
Select an accredited service provider
Identify an Oman Tax Authority (OTA) accredited service provider (or an approved platform when accreditation is opened) to support compliant exchange and reporting. Ensure the provider can handle your expected invoice volumes and supports your ERP landscape.
Set up archiving and record retention controls
Ensure invoices are stored securely with traceability, integrity, and easy retrieval for audit purposes. Align retention settings with local requirements and internal governance so e invoices remain verifiable over time.
Validate ERP readiness for structured invoices
Check whether your ERP can generate invoice data in structured formats such as XML or JSON. If native output is limited, plan an integration approach using middleware, a connector, or an e invoicing layer that can transform your invoice data into the required structure.
Configure, integrate, and test end to end
Set up the integration between your ERP, your e invoicing solution, and the national platform (Fawtara). Run test cycles to validate mapping, business rules, and error handling so invoices flow reliably before go live.
