Hi, @RBCO751 !
Thanks for that context. There is a small fee for every payment processed using Shopify Payments (whether your customer uses a credit card or co-branded debit card). This is standard for all payment gateways. You can find your credit card rate by following these steps!
You can certainly include this fee in your expenses when deciding how to price your product. I recommend checking out our blog post on pricing strategies for more information!
Let me know if you have any other questions.
