Accredited e-invoicing service providers in Oman: what it means and where the official list is
The short answer
An accredited service provider is a company the Oman Tax Authority has approved, after it met the Authority's criteria and passed its tests, to validate and exchange your e-invoices and report their tax data to the Authority. The Authority says the official list appears on its Fawtara portal (fawtara.taxoman.gov.om) and is updated as new providers are accredited; we publish no list and endorse no name. TechMate is not an accredited service provider.
- Only the Oman Tax Authority accredits providers, and the official list is the Authority's, not ours.
- The Authority's FAQ says providers appear on the Fawtara portal once they pass accreditation, and that the list is updated as more are accredited.
- The Service Provider Accredited section of the tax portal (tms.taxoman.gov.om) explains the criteria and guides and points to the Fawtara portal. We found no names in it.
- You connect to a provider through the Fawtara portal, to one provider at a time, and you can switch.
- We are not an accredited service provider, and we do not name or recommend providers.

What does “accredited” mean for a service provider?
In Oman's e-invoicing system your invoice passes through a service provider. The Authority's official FAQ describes its role as validating and exchanging e-invoices between seller and buyer while reporting specific tax data to the Tax Authority. The provider is the party that validates your invoice against Oman's schematron rules.
“Accredited” means the company applied to the Tax Authority, showed it meets the criteria, and passed the Authority's tests. According to the FAQ, accredited providers must meet confidentiality and data-protection requirements, and the Authority monitors their performance. Accreditation does not move your responsibility: the FAQ states that responsibility for a compliant invoice stays with the taxpayer.
Accreditation says nothing about price, customer service or how well a provider fits your software. We found nothing in the official sources that says otherwise, so compare offers yourself.
Where is the official list of accredited providers?
Asked when accredited providers will be announced, the Authority's official FAQ answers that they will “appear on the Fawtara Portal” once they pass accreditation, and that the list will be updated as new providers are accredited.
- Open the Tax Authority's Fawtara portal, the place the Authority says it publishes the list.
- If you start from the tax portal, use its Service Provider Accredited section. It has an “Access Fawtara Portal” button that leads to the same portal.
- Check any name you are given against what the portal shows on the day you decide, not against the provider's own page or an article about it.
What we could not verify: the Fawtara portal loads its content with JavaScript, so we could not read the list itself on 2026-10-11. We do not know how many providers are accredited today and we do not write their names. The tax portal's provider section does not say where the list sits. If you cannot find it on the portal, ask the Tax Authority where it is currently published.
What are the accreditation criteria?
The Tax Authority publishes the criteria on its portal. This is a summary of what we read on 2026-10-11; treat the Authority's page as the authority on any change:
| Criterion | What the Authority says |
|---|---|
| Commercial registration | A mainland commercial registration in Oman with a relevant activity. The FAQ adds that the applicant's own CR, not the parent's, must include two IT-related activities |
| Paid-up capital | At least OMR 6,000, evidenced by the latest audited financial statements or the CR |
| Operating experience | At least two years (not limited to Oman), or one year for Riyada card holders. A parent company's experience can count if the applicant is newly set up |
| Legal and tax standing | A notarised self-declaration of no bankruptcy or criminal record, and no active tax collection process in the Authority's records |
| Technical and security | Architecture documents, multifactor authentication, encryption in transit and at rest, monitoring and incident-response plans, and ISO/IEC 27001 certification |
| Tests | Passing the eDelivery and PINT OM provider-side test suites on the Peppol testbed |
| Peppol membership | Required to receive accreditation, though not for the initial accreditation |
| Providers from outside Oman | May take part if they meet every requirement, including a local presence in Oman |
The FAQ also says there is no deadline to apply, the Authority expects to answer an application within 30 days, any legal structure may apply if it meets the criteria, and the Omanization certificate is not a criterion but a document the Authority asks for its records. Accredited providers must use the Authority's central SMP and may not run their own.
Can my company be its own service provider?
In principle yes. The FAQ says any company that meets the criteria and passes the Authority's tests can be accredited and then serve itself. But that is the full accreditation route above, not a software setting, and it rarely suits a small business. The usual route is to choose an accredited provider.
How do you choose a provider and connect to it?
- Start by asking your invoicing software vendor whether it works with accredited providers and whether it can issue PINT OM invoices directly. The FAQ says your current system can be retained under your arrangement with the provider.
- Take at least two providers from the official list and compare written offers. The comparison questions are on the cost of e-invoicing in Oman page.
- Ask each provider how your invoice file will reach it. The FAQ says how a taxpayer links to a provider's system is not standardised and differs from provider to provider.
- Request the link through the Fawtara portal, which is the route the FAQ gives for connecting a taxpayer to an accredited provider.
- Test a real invoice in the free invoice checker before you pay for any integration, to see what it is missing.
- Do it before your date: the FAQ expects taxpayers to have integrated with their provider on or before their go-live date.
On switching: the FAQ says a taxpayer can disconnect from a provider and connect to another, can be connected to only one provider at a time, and that a provider may start a disconnection but the final disconnection depends on the taxpayer's approval.
A company says it is accredited. How do I check?
- Look for the company's name in the list the Tax Authority publishes on the Fawtara portal. A name that is not there is one neither you nor we can confirm as accredited.
- Ask exactly what the status is: accredited today, applied, passed the tests only, or simply a Peppol member. These are different things, and only the first appears on the list.
- Do not rely on a statement on the company's own website, an article or a post. Rely on the official list.
- If what you were told does not match the list, ask the Tax Authority before you sign.
Where does this site stand?
TechMate is not a service provider accredited by the Oman Tax Authority. This site is a free guide and a structural checker for your invoice files. We do not validate invoices on the Authority's behalf, we report nothing to it, and passing our check does not mean the Authority accepts an invoice. That tells you what you get from this site and what you do not.
Frequently asked questions
What is an accredited e-invoicing service provider in Oman?
A company the Oman Tax Authority has accredited, after it met the Authority's criteria and passed its tests, to validate and exchange e-invoices between taxpayers and report the tax data to the Authority. The FAQ says responsibility for a compliant invoice stays with the taxpayer.
Where can I find the official list of accredited service providers?
The Tax Authority's FAQ says providers appear on the Fawtara portal (fawtara.taxoman.gov.om) once accredited and that the list is updated as more are accredited. The tax portal's provider section shows no names and points to the Fawtara portal. We could not read the list ourselves, so if you cannot find it, ask the Authority.
Is TechMate an accredited service provider?
No. TechMate is not accredited by the Tax Authority and reports no invoices to it. We offer a free guide and a structural invoice checker only.
What are the criteria to become an accredited service provider?
The Authority publishes them. They include a mainland commercial registration with a relevant activity, paid-up capital of at least OMR 6,000, two years of operating experience (one for Riyada card holders), ISO/IEC 27001 certification, security controls, and passing the eDelivery and PINT OM tests on the Peppol testbed. The Authority expects to respond to an application within 30 days.
Can I change my e-invoicing service provider?
Yes, according to the official FAQ: a taxpayer can disconnect from a provider and connect to another, but can be linked to only one at a time. If a provider asks to disconnect, the final disconnection depends on the taxpayer's approval.
How much does an accredited service provider charge?
Each provider sets its own price, which may be a subscription, a per-invoice fee or another model. The Tax Authority charges no fee and does not require providers to charge taxpayers. We found no published price list, so ask for written offers. See the cost page.
Can my company be its own service provider?
Yes if it meets the accreditation criteria and passes the tests; the official FAQ says it can then serve itself. It is a full accreditation process and rarely suits a small business.
