Error · Source: ZATCA E-Invoicing SDK 238-R3.3.8 · Checked: 26 October 2026

What it means

BR-KSA-88 is one of the validation rules for the e-invoice. An error: the invoice is rejected, so fix the cause and send it again. The severity comes from ZATCA's own SDK.

Fields the rule names

The rule text names 3 fields. BT is a single invoice element, BG is a group of elements and KSA is a Saudi-specific element.

• KSA-88
• KSA-37
• BT-5

How to fix it

The steps follow the wording of the rule only; we add nothing ZATCA did not say.

1. Open the invoice XML and find the fields the rule names: KSA-88, KSA-37, BT-5.
2. Correct the value or element in the XML, or in the POS setting that writes it, then generate the invoice again.
3. Check the corrected file with ZATCA's SDK 238-R3.3.8 before you send it.
4. Send the invoice again: the platform rejects an invoice that raises this code.
