To update the payment card saved to your Just Eat for Business account, simply click 'Choose' next to the order on your 'My Meals' page that you'd like to book. Add your chosen dishes to your cart (above your subsidy value), as usual, and beneath 'Total to pay' in the cart on the right-hand side of the page, click on the grey bin icon. This will delete the existing card information held on your account and you can now add new payment details.
