ZATCA E-Invoicing Phase 2: A 2026 Readiness Checklist
Saudi businesses are moving through ZATCA e-invoicing in stages, and Phase 2 brings tighter rules for how invoices are created, formatted and shared with the Fatoora platform. If your finance team still relies on spreadsheets or a basic invoicing tool, now is the time to check your setup against the current requirements. This checklist walks through what Phase 2 means in practice and how to prepare without guesswork.
What ZATCA E-Invoicing Phase 2 Actually Requires
Phase 1, the Generation phase, started on 4 December 2021 and required every VAT-registered business to issue invoices electronically instead of on paper. Phase 2, the Integration phase, has been rolling out since 1 January 2023 in waves grouped by revenue threshold. Businesses in each wave must connect their invoicing system to ZATCA’s Fatoora platform.
Under Phase 2, standard tax invoices for business-to-business sales are cleared by ZATCA before they reach the buyer. Simplified tax invoices, the kind issued to walk-in customers, are reported to ZATCA within 24 hours and must carry a QR code. Every invoice is generated as XML in the UBL 2.1 format, or as PDF/A-3 with the XML embedded, and carries a cryptographic stamp. For the exact wave your business falls into, check ZATCA’s current wave announcements.
Checklist: Is Your Business Ready?
- Your invoicing system generates XML (UBL 2.1) or PDF/A-3 with embedded XML, not plain PDF or Word documents.
- Every simplified invoice carries a QR code and is reported within 24 hours.
- Standard B2B invoices are submitted for clearance before they go to the buyer.
- Your system keeps a tamper-evident log, since each invoice needs a cryptographic stamp.
- Your VAT calculations apply the standard 15% rate correctly across products and services.
- Someone on your team can pull a wave notice from ZATCA and confirm your business’s inclusion date.
Why Many SMEs Still Struggle With This
Small and mid-sized companies in Saudi Arabia often built their invoicing habits around paper or a general accounting template. Moving to a compliant system means more than installing new software. It means rethinking how quotations become invoices, how customer records are stored and how support issues tied to a sale get tracked.
This is where a platform that handles ZATCA e-invoicing alongside customer and quotation records helps. Instead of bolting a compliance patch onto an old system, the invoice, the customer file and the VAT record sit together, so nothing gets missed when a wave deadline arrives.
How Does Phase 2 Change Daily Invoicing Work?
Day to day, the clearance and reporting steps happen automatically once the system is connected to Fatoora. Staff still need to enter accurate line items, apply the correct VAT treatment and issue the invoice promptly. What changes is the margin for error: a manually typed invoice that is missing a QR code or the wrong XML structure can be rejected, which delays payment and creates extra admin work.
Training staff on these two flows takes less time than most teams expect. A half-day session covering which customers get a standard invoice, which get a simplified one, and how to read a rejection notice is usually enough to avoid the most common mistakes in the first few weeks after going live.
Many companies also use the same transition to tidy up related processes. For example, pairing invoicing with an issue reporting and management system means a billing dispute or a delivery complaint is logged against the right invoice number from the start, instead of being chased down later over email.
A Realistic Example: Preparing a Small Retail Business
Picture a Riyadh based retailer that sells to walk-in shoppers and also supplies a handful of corporate clients. Before Phase 2, the owner issued every invoice from a general template, with VAT added manually at 15%. Once the business fell into an active wave, two problems appeared quickly: the walk-in invoices had no QR code, and the corporate invoices were never submitted for clearance before reaching the buyer.
The fix did not require new hardware. The team mapped every sale into one of the two invoice types, connected their point of sale to the simplified flow, and set up the standard flow for corporate quotations. Within a few weeks, rejected invoices dropped close to zero, and staff stopped manually re-checking VAT totals on every receipt.
Standard vs Simplified Invoices at a Glance
| Feature | Standard Tax Invoice (B2B) | Simplified Tax Invoice (B2C) |
|---|---|---|
| Typical use | Business to business sales | Walk-in or retail customers |
| ZATCA process | Cleared before reaching the buyer | Reported within 24 hours |
| QR code | Not required in the same way | Required |
| Format | XML (UBL 2.1) or PDF/A-3 with embedded XML | XML (UBL 2.1) or PDF/A-3 with embedded XML |
| VAT rate | 15% | 15% |
Getting Ready Without Slowing Down Your Team
Preparing for a wave deadline does not have to mean weeks of disruption. Start by listing every place an invoice is created today, including quotations that turn into invoices and any manual VAT entries. Many finance leads also bring in reputable service experts to review current invoice templates and flag gaps before migrating records, which keeps the changeover calm instead of rushed.
Set a realistic internal deadline that sits a few weeks ahead of your wave date, so testing and staff training happen before the pressure builds.
What Should Happen in the First 90 Days After Going Live?
Going live with Phase 2 integration is not the finish line. The first three months are where most formatting issues surface, since real transaction volume tests the system in ways a short pilot cannot. Finance teams should review their rejection log weekly during this window rather than monthly, so a recurring issue, such as a missing field on invoices from a specific point-of-sale terminal, gets caught before it piles up into dozens of unresolved cases.
It also helps to assign one person as the point of contact for anything related to the Fatoora connection, rather than leaving it to whoever notices a problem first. That person can track which invoice types are rejected most often, confirm whether the issue is a system setting or a staff habit, and report patterns to management instead of treating each rejection as a one-off.
Many businesses also use this period to audit whether every sales channel, including any mobile point-of-sale devices or online storefronts, is actually connected to the same invoicing system. A channel that was missed during setup will keep generating invoices the old way, and those gaps are often not noticed until a customer asks why their invoice looks different from one bought in-store.
Frequently Asked Questions
What is the VAT rate used in ZATCA e-invoicing?
The standard VAT rate in Saudi Arabia is 15%, and it applies to taxable invoices generated under both Phase 1 and Phase 2 of ZATCA e-invoicing.
When did ZATCA e-invoicing start?
Phase 1 began on 4 December 2021, requiring electronic invoice generation. Phase 2 has been rolling out since 1 January 2023, in waves based on business revenue.
Do simplified invoices need a QR code?
Yes. Simplified tax invoices, typically issued to retail or walk-in customers, must include a QR code and are reported to ZATCA within 24 hours.
How do I know which wave my business is in?
ZATCA announces waves by revenue threshold. Check ZATCA’s current wave announcements directly, since thresholds and dates are updated periodically.
What should I do if my invoicing system cannot connect to Fatoora?
If your current software cannot generate XML in UBL 2.1 format or connect to the Fatoora platform, look for a replacement well before your wave date arrives. Migrating invoice templates and customer records takes time, so starting the evaluation early avoids a rushed switch close to the deadline.
Conclusion
Phase 2 readiness is less about buying new software and more about making sure invoicing, VAT and customer records work together without manual patchwork. Running through this checklist now, rather than the week before your wave date, gives your team time to fix gaps calmly. If you want to see how invoicing, support and customer issues can sit in one system, book a demo and walk through your own invoice flow with the team.
