Stop losing international sales to surprise import fees. Tax & Duty King shows shoppers the full landed cost — duties, taxes, and fees — directly in the cart and on the product page, before they check out. Supports EU↔UK, UK→US, IOSS, DDP, and multi-origin fulfilment. Reduce cart abandonment, prevent refused deliveries, and build trust with global customers. Coverage for 50+ countries.

Works out of the box with any theme, and looks amazing! Add all the currencies with the push of a button. Convert prices instantly, on any device automatically or change them manually from the Currency Switcher. Since Shopify doesn't allow developers to convert prices on the Checkout page, we came up with a few ways to inform your customers of this. Either with a custom message on the cart page or if they hover over the converted prices, they'll be able to still see the original prices.
