Tiered Gateway Pricing

Create multiple pricing tiers within the same payment gateway rule.

For example:

• Different fixed charges or maximum caps for each tier

Each tier can have its own:

Advanced Rule Targeting

Display or apply gateway fees only when your configured conditions match.

Rules can be targeted by:

• Payment gateway
• Currency
• Customer group
• Customer country
• Included client IDs
• Excluded client IDs
• WHMCS products
• Product addons
• Domain extensions/TLDs
• Billing cycles
• Invoice item types
• Minimum subtotal
• Specific weekdays

Product, addon, TLD, billing-cycle, and invoice-item conditions can use match all or match any logic.

Multiple Calculation Bases

Choose the amount used to calculate each payment fee:

This gives administrators more control over how discounts, credits, and other invoice adjustments affect the final gateway fee.

Scheduling and Usage Controls

• Restrict rules to selected weekdays
• Configure global usage limits
• Set per-customer usage limits
• Assign priorities to competing rules
• Enable or disable rules instantly

Intelligent Rule Conflict Management

When multiple rules match the same transaction, choose how the module selects the winning rule:

Automatic Invoice Updates

Payment fees are automatically evaluated during key WHMCS events, including:

• Invoice creation
• Before an invoice email is sent

If a customer changes the selected payment method, the module removes the previously tracked fee and recalculates the invoice using the newly selected gateway.

Only unpaid or draft invoices are modified, helping protect completed transactions from unwanted changes.

Show compact payment fee badges beside eligible gateway names while preserving the existing gateway-row layout.

Administrators can customize:

• Badge color
• Badge icon
• Public message
• Checkout visibility

• Applicable gateway fee
• Available discount from a compatible discount module
• Estimated price adjustment
• Estimated final total

Additional options include:

• Custom table title
• Estimated amount visibility
• Selected-payment summary
• Automatic selected-row highlighting

The table only displays payment methods available during checkout.
