I'll set up multi-currency functionality for your online store, end-to-end

I set up multi-currency functionality for online stores end-to-end: a customer from any country immediately sees prices and total amount in their own currency, without confusion at checkout. As soon as a visitor lands on the site, I enable currency detection by geolocation — the system automatically selects the right currency when the page loads, but leaves the buyer the option to manually switch if they prefer another.

It's important not just to display a converted price, but to ensure the entire payment process calculates correctly: exchange rates pull from a reliable source and update on time, rounding is configured sensibly, and the amount charged by the payment gateway matches what the customer saw on screen. I've encountered stores where broken or infrequently updated rates caused the storefront price and charged amount to diverge — customers notice this, and trust in the store drops. That's why I always verify the entire chain: from product card to confirmed payment.

What I typically do for such a task:
— connect an up-to-date currency exchange source and configure update frequency
— currency detection by geolocation with manual switcher as a fallback
— correct rounding and price formatting for each currency
— verification of the payment gateway amount against what the customer saw
— testing across all currencies the store actually sells in
