How to Diagnose CS-Cart Checkout Issues That Affect Only One Customer Group

Checkout problems limited to one customer group can be caused by group permissions, pricing rules, tax settings, shipping eligibility, or a custom checkout condition.

What to check

Compare the affected group with a working group using the same products and destination. Review group assignment, checkout permissions, price modifiers, shipping rules, and recent configuration changes.

Recommended next step

Reproduce with a test account and adjust the specific rule after confirming its business intent. Informatix Systems can investigate CS-Cart checkout configuration.
