A fee that works for a domestic payment may leave little margin on a cross-border transaction. For payment providers building a merchant portfolio, or preparing to launch one, knowing where to charge differently is only half the problem. The other half is making that pricing hold up across currencies and transaction types.

Corefy, a unified payment operating system, has introduced fee management with custom rules, giving providers control over how they price payments, refunds, chargebacks, and payouts. Fees can vary by payment method, operation type, and currency, with targeted exceptions for attributes such as card issuer country or transaction amount.

Providers can apply a single percentage rate where straightforward pricing is sufficient. Where it isn't, an advanced mode combines percentage and fixed fees with minimum and maximum limits defined separately for each currency. Custom rules sit above the base configuration and take precedence over it, so a provider can adjust pricing for a particular flow without touching the default rate for everyone else.

A fixed fee or a minimum charge only means something if its currency is clear, and in cross-currency processing a mismatch between the currency a fee is defined in, and the one it's applied in produces charges that don't match what the merchant agreed to. Corefy anchors fees to the payment request currency rather than the processing currency, settling the question at the point the fee is configured.

"Currency ambiguity in fees is expensive in a way that is easy to miss, because nothing breaks at the moment of the transaction. It surfaces weeks later, when a provider is reconciling cross-currency traffic and the totals do not match what the merchant was told," said Taras Khodnevych, Product Manager at Corefy. "Fixing it at the point where the fee is defined is far cheaper than fixing it in a dispute."

Fee management is available to Corefy clients alongside the platform's library of more than 650 ready-made provider integrations.
