Transaction costs vary depending on the payment gateway. Before making a decision, double-check these.
If you use a third-party gateway, Shopify, for example, charges 2% per transaction. You can lower this by upgrading to a more advanced Shopify plan, or you can fully eliminate them by using Shopify Payments, the company’s own payment option. It’s also appealing to merchants who want to choose their own account.
If you’re satisfied with Shopify Payments, however, it won’t make a difference.
