Shopify supports a wide range of external payment gateways. However, there is a significant downside: the platform charges additional fees for using these gateways. This fee is 2 percent, 1 percent, or 0.5 percent for the Basic Shopify, Shopify, and Advanced Shopify plans, respectively. For this reason, if you opt for Shopify, you may want to consider using its payment gateway. WooCommerce also has its own payment gateway that incurs additional costs. However, it doesn’t charge a fee for using external gateways. It means that you’ll only be charged transaction fees by your bank or your chosen gateway.
