Understanding e invoice components is essential for any business in Saudi Arabia aiming to comply with the ZATCA-approved e invoicing system. Since the shift to digital invoicing is now mandatory, companies of all sizes must know exactly what is required in every issued invoice.
This article offers a simplified guide to e invoice components, from basic fields to technical elements, including common mistakes and expert-backed tips from the EZ Integrated team.
What Are E Invoice Components?
E invoice components refer to the specific fields defined by ZATCA to ensure accuracy and transparency. These include:
- Business name and official details
- Seller and buyer VAT numbers (if applicable)
- Invoice number and issuance date
- Item or service description
- Quantity, unit price, and measurement unit
- VAT value
- Total amount with tax
- QR Code – mandatory for simplified invoices
- Digital signature – mandatory in Phase Two
- Approved digital format (XML or PDF/A-3)
These are not just administrative details but legal elements that validate the authenticity of the e invoice.

Paper vs. E Invoice: Why Components Matter
When comparing paper invoices to e invoices, the advantages of e invoice components become clear. Paper invoices are handwritten or printed, making them vulnerable to errors and harder to archive or audit.
In contrast, e invoice components include secure digital features like QR codes, XML formatting, and digital signatures. These ensure tamper-proof documents that are instantly shared with ZATCA, without manual intervention.
E invoicing also integrates directly with accounting systems, speeding up processing and improving financial data control.
Simply put, paper invoicing relies on outdated tools, while e invoicing uses advanced components to ensure compliance and protect both seller and buyer.
Technical View of E Invoice Components
To better understand what happens “behind the scenes,” here’s a quick breakdown of the technical e invoice components:
- XML: A standardized format read by ZATCA systems
- UUID: A unique identifier for each invoice
- Digital Signature: Confirms the invoice is unaltered
- QR Code: Enables mobile verification
- API: The tool that links your system to the FATOORA platform
Even without technical expertise, using a ZATCA-compliant system like those from EZ Integrated ensures these components are handled automatically.
Common Mistakes in E Invoice Components
Despite clear guidelines, many businesses still make common errors:
- Wrong VAT number – leads to invoice rejection
- Missing QR code – especially in simplified invoices
- Using an unsupported format like standard PDF
- Forgetting the digital signature in Phase Two
- Failing to match mandatory XML fields
These mistakes are avoidable with a compliant system and a skilled technical team.
