Cross-Border Merchants Look Beyond Headline Processing Rates

Cross-border merchants risk understating payment costs when they compare providers solely on domestic acquiring rates. Umair Ahmed, a senior software developer at PSPC, said international transactions can add network assessments, acquirer surcharges, foreign-exchange spreads and tax costs. Offshore acquiring may also depress authorization rates as issuing banks apply unfamiliar fraud controls, turning a seemingly cheaper quote into a more expensive arrangement once lost sales are included.

In a Finextra commentary published on Sept. 4, 2026, Ahmed said published US domestic rates typically range from 1.5% to 3.5%. Stripe adds 1.5% for international cards and another 1% for currency conversion, while HaiPay lists outbound foreign-exchange fees of 1% to 2.5%, depending on the market. On $10 million of international volume, each percentage point of authorization performance represents $100,000 in orders, dwarfing a headline-rate advantage of 20 basis points.
