How does a cross-border fee work?
Each card payment has an issuer country, which the BIN reveals, and an acquiring country, where the merchant’s acquirer processes it. When the two differ, the scheme treats the payment as cross-border and charges the acquirer an additional assessment, sometimes with a higher rate when the payment is not settled in the acquirer’s local currency. Checkout.com notes that Visa introduced its International Service Assessment in 2008 to cover the added cost and risk of cross-border processing, and that Mastercard, American Express and Discover charge similar fees.
Why does it matter?
Cross-border fees are easy to miss in a blended price and large at scale. As an illustrative example: a merchant processes 2 million euros a month of payments from cards issued outside its acquirer’s country. An extra 1% in cross-border assessments costs 20,000 euros a month, before any differences in interchange or currency conversion are counted.
How can merchants reduce them?
The main lever is local acquiring: processing payments through an acquirer in the card’s issuing country, so the scheme treats them as domestic. Antom notes that domestic routing follows the domestic interchange schedule and avoids cross-border surcharges, though it may require a local entity. Choosing the settlement currency carefully and asking for interchange plus plus pricing, which shows scheme fees line by line, also help merchants see and manage the cost.
Where does Omno use it?
Cross-border fees are charged through each acquirer or PSP; Omno does not set them. Card attributes such as issuing country are among the conditions Omno’s routing rules can use, so traffic for a card country can go to a PSP route that acquires domestically there, and the routing-decision log and reporting show which route processed each payment.
