For newly formed companies in Saudi Arabia, e-invoicing compliance is no longer a future concern — it is an operational requirement that should be addressed during or immediately after company formation.
ZATCA’s e-invoicing system (Fatoorah) operates in two phases. Phase 1 (Generation) has been mandatory since December 2021. Phase 2 (Integration) requires companies to connect their invoicing systems directly to ZATCA’s platform and is being rolled out in successive waves based on revenue thresholds.
This article explains what new entities need to know, the current integration timelines, technical requirements, and how to prepare early to avoid compliance gaps.
Phase 1 vs Phase 2: What New Companies Must Understand
Phase 1 – Generation
All VAT-registered companies must issue and store electronic invoices that meet ZATCA’s technical standards. Paper invoices and simple PDF invoices generated outside a compliant system are not acceptable.
Phase 2 – Integration
Companies in a designated wave must integrate their e-invoicing solution with ZATCA’s Fatoorah platform. Standard tax invoices (B2B) require clearance by ZATCA before they can be shared with the buyer. Simplified tax invoices (B2C) must be reported to ZATCA within 24 hours of issuance.
New companies that register for VAT should assume they will eventually fall under Phase 2 and plan accordingly.
Current Integration Timelines (as of late 2026)
ZATCA continues to expand Phase 2 through revenue-based waves. The most recent major wave (Wave 25) covers taxpayers whose VAT-subject revenue exceeded SAR 187,500 in any of the years 2022, 2023, 2024 or 2025. Integration for this wave must be completed by 1 February 2027.
Earlier waves with higher revenue thresholds have already passed or are in progress. ZATCA notifies affected taxpayers directly and provides at least six months’ notice before the integration deadline.
Even if a newly formed company has not yet reached a revenue threshold that triggers a specific wave, preparing a Phase 2-compliant system from the outset is the most efficient approach.
Technical Requirements for Phase 2 Compliance
To meet Phase 2 standards, an e-invoicing solution must be able to:
- Generate invoices in XML format (or PDF/A-3 with embedded XML)
- Apply a cryptographic stamp using a Cryptographic Stamp Identifier (CSID) issued by ZATCA
- Include a unique UUID for each invoice
- Generate a compliant QR code with the required data fields
- Maintain an invoice hash chain linking each invoice to the previous one
- Integrate with ZATCA’s Fatoorah platform via API for clearance and reporting
- Securely archive invoices for the required retention period
Selecting a solution that already supports these capabilities reduces future disruption.
How New Companies Should Prepare During or Immediately After Formation
1. Confirm VAT Registration Status
E-invoicing obligations apply to VAT-registered entities. New companies should determine early whether VAT registration is mandatory or voluntary based on expected turnover.
2. Select a Compliant E-Invoicing System Early
Avoid basic invoicing tools that only satisfy Phase 1. Choose a system that is already Phase 2-ready or can be upgraded without major rework.
3. Align Accounting and Invoicing Processes
Ensure the chosen system integrates with the company’s accounting processes so that invoice data flows accurately and consistently.
4. Plan for Device/Unit Onboarding
Under Phase 2, each device or unit that issues invoices under the company’s VAT number must be onboarded with ZATCA. This step should be factored into the setup timeline.
5. Monitor ZATCA Notifications
ZATCA communicates wave assignments and deadlines through official channels. New companies should ensure their registered contact details are accurate and actively monitored.
6. Build Internal Awareness
Finance and operations teams should understand the difference between clearance (B2B) and reporting (B2C) processes, as well as the consequences of non-compliant invoices.
Risks of Delayed Preparation
Companies that postpone e-invoicing readiness often face compressed implementation timelines once they receive a wave notification. Common issues include last-minute system changes, data migration problems, staff training gaps, and temporary disruption to invoicing and cash flow. Non-compliant invoices can also lead to penalties and operational complications with customers and banks.
Key Takeaway
E-invoicing readiness should be treated as part of the post-formation operational checklist, not as a later compliance project. New companies that select a Phase 2-compliant solution early and configure it properly from the beginning avoid reactive projects and reduce the risk of penalties or operational interruptions as their revenue grows.
