This is not ZATCA’s official system. Businesses under Phase 2 (Fatoora integration) need an approved e-invoicing system.
A simplified tax invoice in Saudi Arabia carries a QR code with five details: the seller’s name, the VAT number, the time of the invoice, the total with VAT and the VAT. This tool builds that code in the format ZATCA asks for (TLV, then Base64) and draws the QR.
You can also paste the Base64 text from a QR to see what is inside it. Everything is worked out in your browser and nothing you type is sent anywhere.
How to use it
- Enter the seller’s name and the 15-digit VAT number.
- Enter the date and time of the invoice.
- Enter the total with VAT, and the VAT (or tick 15% to work it out).
- Download the QR as PNG or SVG, or copy the Base64 text.
Questions
Is this the official ZATCA system?
No. It makes the Phase 1 (generation) QR code for a simplified invoice. Businesses under Phase 2 (integration with the Fatoora platform) must use an approved e-invoicing system that signs each invoice and reports it to ZATCA.
What is inside the QR code?
Five fields in TLV form (tag, length, value): 1 seller name, 2 VAT number, 3 invoice time (ISO 8601), 4 total with VAT and 5 VAT. The bytes are joined and written as Base64, and the QR holds that text.
Why does an Arabic seller name need more space?
The length in TLV counts UTF-8 bytes, not letters. Each Arabic letter takes 2 bytes, so مؤسسة النور has 11 letters but 21 bytes. The tool counts bytes.
What is a valid Saudi VAT number?
15 digits that start with 3 and end with 3, for example 310122393500003. The tool warns you when the number does not match.
Which time should I enter?
The time on the invoice. Choose Saudi time (UTC+3) or UTC; the code always stores the time in UTC, ending in Z, as in ZATCA’s examples.
