This ZATCA E-Invoicing (FATOORA) Phase 2: Integration, Clearance and Compliance session in Dubai runs from Monday 19 April to Friday 23 April 2027 (week 16, Q2 2027). It is the 1st of 2 dates in Dubai in 2027, at a fee of 19,500 SAR, the same for each of them. Registration is open for this date. It is held in person at Five-star CBD venue.
Saudi Arabia's Zakat, Tax and Customs Authority (ZATCA) is extending the FATOORA Integration Phase wave by wave: Wave 24 taxpayers had to integrate by 30 June 2026, and Wave 25, covering VAT-taxable revenue above SAR 187,500, must integrate by 1 February 2027. Standard tax invoices are cleared before issue and simplified invoices reported within 24 hours, so errors surface as rejected invoices and blocked sales. This Core Concept course takes finance, tax and systems teams hands on through UBL 2.1 mapping, onboarding, validation and controls. Participants leave with a FATOORA Integration and Compliance Readiness Pack.

Carry out the FATOORA onboarding sequence from certificate signing request to production cryptographic stamp identifier (CSID)
Validate invoice XML, digital signatures, QR codes and hash chains using the ZATCA SDK and platform compliance checks

Conclusion
Under FATOORA every invoice is a tax event that must be right the first time. This course moves from ZATCA's clearance and reporting models and integration waves, through the UBL, signature and hashing standards behind them, to hands-on onboarding, validation and the exceptions that cause most failures. The final day brings that work together in a FATOORA Integration and Compliance Readiness Pack, giving participants a tested basis for going live, adding branches and devices, and keeping invoicing compliant as ZATCA requirements evolve.
ZATCA E-Invoicing (FATOORA) Phase 2: Integration, Clearance and Compliance runs in Dubai over 5 days, with 2 upcoming dates in Dubai. The course fee is 19,500 SAR.
