Programme overview
Technical depth: Practitioner · Practical mode: Lab
Introduction
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.
Course Objectives
- Apply the correct ZATCA clearance or reporting flow to standard and simplified tax invoices, credit notes and debit notes
- Map ERP and point-of-sale data fields to the UBL 2.1 structure and business rules of the ZATCA XML implementation standard
- 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
- Operate controls for rejected invoices, offline periods, corrections and archiving that keep invoicing continuous and auditable
- Produce a FATOORA integration and compliance readiness pack for sign-off by finance and IT leadership
Target Audience
- Accountants and billing staff responsible for issuing and correcting tax invoices
- Tax compliance staff accountable for invoice content and ZATCA reporting deadlines
- ERP and point-of-sale analysts configuring e-invoicing solutions
- Integration developers connecting billing systems to the FATOORA platform
- Internal control and IT audit staff testing e-invoicing processes and records

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.
