Make permitted payment-related adjustments easier to explain, so customers can understand the charges associated with their chosen payment method.
Businesses that accept several payment methods may need a consistent way to explain permitted payment-related adjustments. This module supports a defined billing policy so that customers and staff have a clearer understanding of how those adjustments relate to an invoice.
Your team decides which payment methods may carry an adjustment and documents the conditions. A customer uses an applicable payment method, then reviews the invoice explanation. Staff can compare that scenario with the business policy when responding to a billing query.
The module sits within your WHMCS billing workflow alongside the payment integrations already used by the business. It helps apply the configured policy while the selected gateway remains responsible for processing the payment.
Whether a surcharge is permitted depends on the payment provider and applicable rules. The module does not grant permission to impose a charge or determine your tax treatment. Additional billing policies and integration-specific changes can be reviewed separately.
