A compliant e-invoicing solution, purpose-built for VAT in Saudi Arabia

Accurate, effortless e-invoicing from the first time.

Electronic invoicing (e-invoicing) becomes mandatory in the Kingdom of Saudi Arabia with Phase 1 coming into effect from 4 December 2021. 

Under this first phase of the new regime, taxpayers must be able to generate and store Tax Invoices as well as Credit / Debit Notes electronically using a fully compliant software system. As this is a 2 phase process companies must ensure they are compliant from the start.

E-invoicing Compliance

Who does this apply to?

All taxpayers (excluding non-resident taxpayers) and any other parties issuing tax invoices on behalf of suppliers subject to VAT.

Is your business ready?

From 4 December 2021, all impacted taxpayers must comply with the following requirements for Phase 1.

Phase 2 is set to be launched early 2023.

Requirement 1

Stop issuing manual invoices:

Invoices written by hand or created with text editing tools are not considered compliant.

Requirement 2

Use a compliant e-invoicing solution: 

Your technology must meet the requirements and specifications published under the e-invoicing laws and regulations issued by the Zakat, Tax and Customs Authority (ZATCA).

During Phase 1, your e-invoicing system must be able to: 

  • Generate e-invoices with the required elements including QR codes
  • Timestamp the e-invoice copies archived in the solution

Requirement 3

Ensure your e-invoicing solution prohibits: 

Uncontrolled access, software time change, tampering of e-invoices or logs, and multiple invoice sequences.

Requirement 4

e-invoices must include the required additional fields: 

  • Tax Invoices must include the buyer’s VAT registration number if the buyer is a registered VAT taxpayer, in addition to the invoice type description as a title. A QR code can be added (this is optional).
  • Simplified Tax Invoices must include a compliant QR code, in addition to the invoice type description as a title.
