Order total must be greater than zero

Overview 

Checkout validation error when total is 0.00.

Root Cause 

• All items are free or discounts equal the subtotal, and no “free” gateway is configured.

Impact 

• Checkout blocked.

How to Fix the Issue 

1. Add a paid item or remove discounts.
2. Enable a zero-total flow (e.g., “Cheque”/“Bank transfer” or a dedicated free-order gateway) if you accept free orders.

Additional Notes 

• Some gateways reject 0.00 totals by design.
