Improved Validation for Business Checkout Fields

To enhance data accuracy and prevent misclassification, the checkout process now enforces a validation rule for business customers: the fields Company Name and VAT ID must either both be filled or both left blank.

If only one of the two is provided, the customer is shown a clear error message and prompted to correct the input before proceeding.

This change ensures that customers are not mistakenly tagged as business customers with incomplete information, which previously could affect tax handling, invoicing logic, and customer segmentation in integrated systems.

No action is needed from merchants; the rule is applied automatically for all checkouts across AI Commerce Cloud stores.
