UBL 2.1 Invoice Standard for ZATCA: Technical Guide
The Kingdom of Saudi Arabia (KSA) is transforming its tax landscape with the implementation of e-invoicing, driven by the Zakat, Tax and Customs Authority (ZATCA). A crucial aspect of this transformation is adherence to the UBL 2.1 invoice standard. This guide provides a comprehensive technical overview of UBL 2.1 for ZATCA e-invoicing, helping businesses understand and comply with the regulations. Whether you're preparing for Phase 1 (already passed) or the upcoming integration phase deadlines, this guide will prove invaluable.
What is UBL 2.1?
UBL, or Universal Business Language, is a library of standard XML business documents, such as invoices, purchase orders, and dispatch advices. UBL 2.1 is a specific version of this standard, widely adopted for its structured and machine-readable format. For ZATCA e-invoicing, UBL 2.1 is the preferred format for generating compliant invoices.
Using UBL 2.1 ensures interoperability between different systems and facilitates automated processing of invoice data. This leads to faster payment cycles, reduced errors, and improved efficiency.
Why is UBL 2.1 Important for ZATCA E-Invoicing?
ZATCA mandates the use of UBL 2.1 (with specific ZATCA customizations) to standardize electronic invoices in Saudi Arabia. By adhering to this standard, businesses ensure that their invoices are easily verifiable, secure, and compatible with ZATCA's systems. Failure to comply can result in penalties and disruptions to business operations.
Specifically, ZATCA uses a subset of UBL 2.1 tailored to the Saudi Arabian context, with mandatory and optional fields defined in their documentation. Understanding these specific requirements is key to successful e-invoicing compliance.
Key Components of a UBL 2.1 ZATCA Invoice
A UBL 2.1 invoice comprises various elements, each representing a specific piece of information. Here are some of the most important:
- Invoice Header: Contains basic information about the invoice, such as invoice number, issue date, and document currency.
- Seller (Supplier) Party: Details about the company issuing the invoice, including its name, address, VAT registration number, and other relevant details.
- Buyer (Customer) Party: Details about the company receiving the invoice, similar to the seller party information.
- Invoice Line: Contains details about each individual item or service being invoiced, including the description, quantity, unit price, and applicable taxes.
- Tax Total: Summarizes the total amount of tax levied on the invoice. This includes details about the tax type (VAT, etc.), tax rate, and taxable amount.
- Legal Monetary Total: The final total amount due on the invoice, including taxes, discounts, and other charges.
- Digital Signature: A cryptographic signature ensures the invoice's authenticity and integrity.
- QR Code: A mandatory QR code containing key invoice data, enabling easy verification by ZATCA and customers.
Mandatory and Optional Fields in UBL 2.1 for ZATCA
ZATCA specifies which UBL 2.1 fields are mandatory and which are optional. It is crucial to understand these requirements to avoid rejection of your invoices. Some key mandatory fields include:
- VAT Registration Number (for both Seller and Buyer, where applicable)
- Invoice Issue Date and Time
- Invoice Number
- Item Description
- Item Quantity
- Item Unit Price
- VAT Amount
- Total Invoice Amount

While optional fields may not be required for all invoices, including them can enhance the invoice's clarity and completeness. Refer to the official ZATCA e-invoicing specifications for the latest list of mandatory and optional fields.
