Not all online store builders charge transaction fees - BigCommerce, for example, do not charge transaction fees in all their plans. However, if they do, the fees usually range from 0.5% – 3% – depends on the plan you are using. Here are two examples: Shopify Transaction Fees Basic Shopify: 0 – 2% for external payment gateways Shopify: 0 – 1% for external payment gateways Advanced Shopify: 0 – 0.5% for external payment gateways For usage of all major credit cards (Visa, Mastercard, American Express, JCB, Discover, and Diners Club debit and credit cards), you’ll need to set it up by going to the accept credit card section and selecting Shopify payments. Weebly Transaction Fees Weebly adds a 2.9% service charge + $0.30 transaction fee for Stripe, Authorize.net, and PayPal.
