A: Rounding can be configured for separated payment type, for example, you may need to enable total billing Rounding for Cash payment while Rounding is not applicable on your Credit Card billing, follow the steps below to enable/disable rounding for different payment type:
1. On your Controller, configure your default rounding under Setting->Receipt Configure -> "Payment Total Rounding"
2. Enable configured rounding for each payment type under Setting->Payment Type -> select "Yes" or "No" under "Payment Total Rounding" for each payment type to enable/disable rounding
