A product SKU is required on each product in BigCommerce to redirect checkout. Products with variations must have a SKU on each variation. Products without variations must have a SKU on the product.

To redirect the BigCommerce cart to the Checkout Champ checkout page, it is required to manually set the routing on your BigCommerce cart page.
