Oman E-Invoicing: Flick Network Is Now a Pre-Approved Fawtara ASP

Flick Network is now a Pre-Approved Accredited Service Provider (ASP) for Oman's Fawtara e-invoicing program, which is administered by the Oman Tax Authority (OTA). The OTA has confirmed through its official Tax Portal that Fawtara will roll out in four phases, beginning with 100 large VAT-registered taxpayers in August 2026.

This guide explains what Pre-Approved ASP status means, what the OTA's published accreditation criteria require, and how Flick Network helps Omani businesses prepare for compliance from day one.

What Does Pre-Approved ASP Status Mean Under Fawtara?

Pre-Approved ASP status means the Oman Tax Authority has reviewed a service provider against its published Service Provider Criteria and recognized that provider as eligible to support the Fawtara rollout. Businesses can appoint a Pre-Approved ASP today to begin systems integration, data mapping, and staff training well before their own phase deadline arrives.

The OTA requires providers to show genuine financial and operational stability before reaching this stage. This includes valid commercial registration in Oman, a minimum paid-up capital of OMR 60,000, a proven track record of one to two years in business, and a clean legal and tax history with no outstanding debts to the Authority. 

Security is the other major pillar of the criteria, since service providers handle sensitive invoice and tax data on behalf of every business they support. The OTA requires encryption, multi-factor authentication, active security monitoring, and a documented incident response plan as proof that a provider can protect this data. ISO/IEC 27001 certification for information security management is the specific standard the OTA uses to confirm these protections are in place. Flick Network already holds this ISO/IEC 27001:2022 certification, along with ISO 22301:2019 certification for business continuity, giving Omani businesses a service provider whose security and operational standards are independently verified rather than self-declared. 

Oman's Fawtara E-Invoicing Rollout: Phases and Timeline

The Oman Tax Authority confirms that Fawtara will roll out across four phases, with each phase targeting a specific group of VAT-registered taxpayers. Businesses outside an early phase can still adopt Fawtara voluntarily, since the OTA allows optional early adoption with the necessary technical support provided. 

How Fawtara's Five-Corner Model Works

Fawtara is built on a five-corner model, the structured exchange framework that forms the backbone of the entire program. Under this model, every invoice passes through five distinct points before it reaches the buyer and is reported to the tax authority. Service providers occupy corners two and three of this model, validating and exchanging invoices on behalf of the taxpayers at corners one and four. 

Here is how an invoice moves through each of the five corners from issuance to final reporting:

1. The supplier issues the e-invoice from their accounting or ERP system at corner one of the model.

2. The supplier's service provider receives the invoice and validates it against OTA rules at corner two.

3. The invoice is exchanged with the buyer's service provider for onward delivery at corner three.

4. The buyer receives the invoice data directly from their own service provider at corner four.

5. The Oman Tax Authority receives the corresponding tax data at corner five for compliance monitoring.

What Oman's Official Guidance Confirms About E-Invoicing Requirements

Businesses preparing for Fawtara compliance need to understand the obligations the OTA has already confirmed through its official Tax Portal. The Authority states plainly that companies must issue invoices electronically using approved formats, work with a certified service provider or a compatible ERP solution, and report invoices to the OTA on time. Businesses should also keep monitoring the Tax Portal for the final data dictionary, which the OTA has confirmed it will release after completing its current consultation. 

Here are the core e-invoicing requirements every business must follow once Fawtara becomes mandatory:

• Invoices must be issued electronically through an approved system, since the OTA's own portal confirms paper and manual processes will not satisfy the Fawtara mandate.

• Every invoice must be validated and exchanged through a certified service provider, since direct submission without an accredited provider does not meet OTA requirements.

• B2B e-invoices must be transmitted to the buyer and reported to the OTA in real time once a business enters its mandatory phase. 

• For B2C transactions, the OTA has confirmed that the seller's service provider will report the invoice data to the OTA, while the seller can continue to provide a human-readable invoice to the customer within the existing 15-day invoice issuance period. The required QR code specification for that human-readable invoice has not yet been published. 

• Detailed technical specifications, including the exact data fields, invoice format, and document structure, remain part of a draft data dictionary still under OTA consultation with Rollout 1 taxpayers and prospective service providers.

How Businesses Can Get Started With Fawtara Compliance

Businesses in Oman do not need to wait until their official phase begins to start preparing for Fawtara, and early preparation significantly reduces the risk of last-minute compliance issues. The following steps reflect the practical preparation path that aligns with the OTA's published guidance for businesses preparing ahead of their mandatory phase. 

1. Confirm your VAT registration status and check whether your business has already been notified for Phase 1 by the OTA.

2. Review your current invoicing process and identify whether your ERP or billing system can issue invoices electronically.

3. Appoint a certified ASP, such as Flick Network, to handle validation and OTA reporting on your behalf. 

4. Clean and verify your master data, including customer VAT numbers, legal names, and product or service tax categories.

5. Engage early with OTA awareness sessions and technical updates so your team understands each requirement as it is finalized.

6. Train your finance and accounting teams on the upcoming invoicing workflow, including how to manage corrections and exceptions.

7. Stay connected with your appointed service provider so your systems update automatically once the OTA finalizes its technical specifications.
