Implementation of mandatory e-invoicing in Saudi Arabia

Saudi Arabia is implementing a two-phase mandatory e-invoicing system across all economic sectors, led by the Zakat, Tax and Customs Authority (ZATCA):
- December 4, 2021 – Phase 1 ("Generation Phase"): All VAT-registered businesses in Saudi Arabia were required to begin issuing electronic invoices instead of paper invoices. This phase mandated the use of structured formats, inclusion of required fields (like QR codes), and the use of compliant e-invoicing solutions. However, no real-time submission to authorities was required yet.
- January 1, 2023 – Phase 2 ("Integration Phase"): Businesses exceeding a certain revenue threshold (initially SAR 3 billion, then progressively lower) were required to integrate their e-invoicing systems with ZATCA’s Fatoora Platform. Invoices must be cleared in real time or reported within 24 hours of issuance. ZATCA provides specific APIs and security protocols for integration.
- 2024–2025: Phase 2 is being gradually extended to medium and small-sized businesses in waves. ZATCA publishes lists of affected taxpayers and implementation dates several months in advance. All covered taxpayers must comply with both generation and integration requirements, including system readiness and digital certificate installation.
