What data is required for a client to comply with ZATCA requirements?

The system automatically detects the client type (Business or Personal) directly from the client linked to the invoice and applies the appropriate validation rules for each type when the invoice is sent to ZATCA.

Business clients:

• A VAT Registration Number or a Commercial Registration / Unified Number (C.R) is required — either one on its own is enough, and having both is fine too.
• Business Name and Country are always mandatory.
• If the business client is outside Saudi Arabia, the system displays one or two local tax-identifier fields whose label changes automatically based on the selected country.

Personal (individual) clients:

• No Commercial Registration or VAT number is needed.
• If the client’s country is Saudi Arabia, a single field labeled “Unified Number” appears, accepting one of three formats: 10 digits (Commercial Registration or National ID), 15 digits (Tax Number), or a passport number.
• If the client’s country is not Saudi Arabia, no tax-identifier or ID field is shown at all.
