Frequently asked questions

Everything you might want to know before you upload your invoice.

Is Oman Fawtara an official certification?
No. Oman Fawtara is a technical readiness assessment, not certification, legal advice, tax advice, or a decision by any tax authority. It evaluates your invoice against a versioned, source-attributed rule set so you can see which technical requirements are met and which are missing.
Is the assessment free?
Yes. You can start a free assessment without an account. Optional follow-up services, such as a consultation with a consultant, may be offered separately and are never required to see your result.
Which invoice formats are supported?
You can upload a PDF, XML (UBL/PINT-OM), JSON, CSV or XLSX. One representative sales invoice is enough for the assessment.
Is my invoice private and safe?
Yes. Uploads are stored in a private environment, validated and hashed on receipt, and never reused or shared without your consent. You can request deletion at any time.
Is a PDF the same as a structured invoice?
No. Only a structured XML invoice (e.g. UBL/PINT-OM compliant XML) is treated as a structured invoice. A PDF is treated as observed text and is never presented as equivalent to a structured invoice.
Do I need an account?
No account is required. You can go from upload to result in one flow, and your business details remain optional.
How long does the assessment take?
Processing is usually completed in seconds to minutes depending on the file type and server load. The results page refreshes automatically and also works without JavaScript.
Is the score a legal compliance percentage?
No. The score is a product-readiness indicator, not a legal compliance percentage. It shows how your invoice and systems line up with the rule set we run.
What does “versioned rule set” mean?
Every rule references the technical framework and source it is based on, with a version and link. Draft or unverified rules are excluded from scoring so the result stays deterministic and auditable.
Can I get help interpreting my result?
Yes. After you see your results you can optionally leave your details, complete a short questionnaire about your systems, and request a complimentary consultation.
