Six countries, six programmes, one direction of travel. We keep this tracker current as the mandates move.
| Country | Programme | Standard | Status | Next milestone |
|---|---|---|---|---|
| Saudi Arabia | ZATCA FATOORA | UBL 2.1 XML — centralized clearance, not Peppol | Live since Dec 2021 / Jan 2023 | Wave 24 (> SAR 375k) by 30 Jun 2026 |
| UAE | MoF/FTA eInvoicing (DCTCE) | PINT AE — Peppol 5-corner | Pilot 1 Jul 2026 | ASP deadline 30 Oct 2026; Phase 1 live 1 Jan 2027 |
| Oman | OTA Fawtara | Peppol 5-corner; Oman PINT expected | Accreditation open since May 2026 | Pilot with 100 largest VAT payers, Aug 2026 |
| Qatar | MoF/GTA (draft law) | TBD — Peppol expected by analysts | Draft law approved 6 May 2026 | Shura Council review; no official dates |
| Bahrain | NBR (design stage) | TBD | Nationwide B2B system in design | Announcement anticipated; no confirmed dates |
| Kuwait | — | TBD | Early-stage intentions only | None published |
Reading the six rows
Saudi Arabia proved the model. FATOORA's centralized clearance — cryptographic stamps, QR codes, hash chains — has been grinding through Phase 2 integration waves by turnover since January 2023; Wave 23 (> SAR 750k) closed in March 2026 and Wave 24 reaches businesses above SAR 375k by the end of this month. It is the region's compliance proving ground, and deliberately not Peppol.
The UAE made the architectural counter-move: a decentralized 5-corner model where accredited private providers carry the exchange and report to the FTA. Choosing Peppol PINT AE pulled the Emirates into a global interoperability network rather than a national silo — and Oman followed within months, becoming a Peppol Authority in January 2026 with a structurally identical model. Two adjacent Peppol CTC systems is no coincidence; it's a template.
Qatar approved its draft law (covering B2B, B2G and B2C) in May 2026 — remarkable for a country yet to implement VAT, and a signal that e-invoicing is arriving as foundational tax infrastructure rather than a VAT afterthought. Bahrain is designing; Kuwait is watching.
The pattern that matters for providers
Three regularities run through every GCC programme so far. First, phased rollouts by size, largest taxpayers first — meaning the early enterprise cohort decides who the reference providers are. Second, accredited-provider models — the authority outsources the pipes but gates who may operate them, making accreditation the market moat. Third, after Saudi's bespoke build, Peppol as the default — UAE confirmed, Oman confirmed, Qatar expected.
For a service provider, the strategic conclusion is uncomfortable but simple: country-by-country integration stacks compound in cost with every new mandate, while the underlying job — getting clean invoice data out of the same regional ERP estates (SAP, Oracle, Dynamics, Tally, Zoho, Focus) — never changes. That is the case for a country-agnostic connector layer: build the extraction once, treat each Gulf mandate as a rule-pack, and be ready the day each authority publishes its specification.
Building a GCC strategy?
Saudi live, UAE in months, Oman piloting, Qatar drafting. One connector layer covers the lot.
