Create and manage Custom Fee rules

Custom Fee rules allow you to define additional Fee configurations for specific transaction scenarios based on predefined conditions. They provide flexibility beyond the default Base fee, enabling different Fees to be applied depending on the transaction attributes and business requirements.

Each Custom Fee rule can override the Simple rate-only or Advanced multi-currency Base fee configuration when its conditions are met. If no Custom Fee rule matches the transaction conditions, the system uses the configured Base fee as a fallback.

Custom Fee rules cannot exist independently of a Base fee. A Base fee configuration is always required to ensure that a default Fee is available when no specific Rule applies. Custom Fee rules can be created and managed only when Fee availability is enabled for the Payment or Payout method.

Create Custom Fee rule

Go to Processing and choose the Payment scheme you previously created on the grid.
Navigate to the Payment methods or Payout methods tab of the specific Payment scheme. Click the particular Method on the grid.
Navigate to the Fees tab.
Switch on the Fee availability toggle.
Then, set up a Base fee as a fallback. To learn more, go to the Add Base fee guide.
Click Create Fee rule.
Select the preferred Currency.
Specify the Transaction type.
Insert the values for the corresponding fields: Rate, Fixed, Min, and Max.

Build a Condition

Each Rule specifies the condition, which consists of three parts: the Condition attribute, Operator and Value field.
Select the Condition attribute from the following ones:

Condition	Description
Currency	Defines the currency of the transaction used to determine whether the Custom Fee rule applies.
Transaction type	Specifies the type of transaction to which the Custom Fee rule applies, such as Payment, Refund, Chargeback, or Payout, depending on the Method.
Card issuer country	Defines the country where the card issuer is located, allowing the Rule to apply to transactions made with cards issued in a specific country.
Transaction amount	Specifies the transaction amount or amount range used to determine whether the Custom Fee rule applies.
Card network	Defines the card network used to process the transaction, such as Visa or Mastercard, allowing the Rule to apply to transactions processed through a specific network.
Card brand	Specifies the card brand associated with the payment card, allowing the Rule to apply to transactions made with a particular card brand.

Select the Operator after analysing the corresponding Attribute & Operator matrix:

Operator → Attribute ↓	Equals to	Not equal to	Equals any of	Not equal any of	Greater than	Greater or equal	Less than	Less or equal
