Multi-currency payments for e-commerce: keep more of every foreign sale

When an online store sells to customers abroad, card processors can add international card fees and currency conversion fees on top of the normal rate. Pricing in your customers’ currencies and keeping those currencies in a multi-currency account, instead of converting every sale, can noticeably lower your costs.

Key takeaways

  • Foreign sales can carry extra card and conversion fees.
  • Conversion fees vary by processor.
  • Holding foreign currency avoids converting every payout.
  • Merchants of record also handle sales tax abroad.

A worked example

A Canadian store sells C$50,000 a month to US customers and converts every sale to CAD.

ProcessorMonthly conversion fee
Shopify Payments (1.5%)About C$750
Stripe (2%)About C$1,000

If the store keeps USD sales in USD and pays US costs from them, much of that conversion cost can be avoided.

How to keep more of each sale

  • Price in your customers’ currencies where your platform supports it.
  • Get paid out in those currencies into a multi-currency account.
  • Pay foreign costs from foreign balances, and convert only the surplus.
  • Consider a merchant of record if global sales tax is a burden.

Common mistakes

  • Converting every foreign sale to CAD automatically.
  • Comparing processors on domestic rates only.
