Can my customers see and pay in their own currency on my portal?

Yes, a white label portal can show prices in more than one currency, and you decide which currencies your customers are allowed to choose from. One currency is set as the base for your business, and the others are shown by converting from that base using an exchange rate that is refreshed regularly. Your customer picks the currency they are comfortable with, and the search results, the fare rules and the final page all follow that choice.

The part that catches people out is the difference between the currency shown on screen and the currency the money actually moves in. A customer may see and understand the price in their own currency, but the payment gateway and the supplier behind the booking may still charge in the currency the fare or the room was originally quoted in. Which one your customer is billed in depends on the gateway you use and the agreement you have with it, not on the portal alone.

Be ready for small differences. A converted price is a conversion and not a real quoted price, so the amount on the card statement can differ slightly from the amount on the screen, and the bank may add its own charge on top. Refunds usually come back at the rate applied on the day of the refund rather than the day of booking. Some suppliers also quote in one currency only, and in those cases the other currencies shown are always a conversion.

The sensible next step is to confirm with your payment provider which currencies they can actually settle in, then switch on only those currencies and add a short line at the payment step explaining that the final amount may vary a little.
