We need to set up a custom logic and display order for delivery and payment methods on the checkout page of our BigCommerce webshop. The goal is to make the checkout process simple and clear for customers. The delivery options should change dynamically depending on the total order amount, and the available payment methods should depend on the selected delivery method. All delivery and payment options already exist in the system — we only need someone to implement the correct conditional logic and order of display so everything works smoothly on the checkout page. If you’ve handled BigCommerce checkout customisation before and can turn this around quickly, I’d love to get started right away.
