Passing credit card fee as a surcharge to the customer if paid by credit card or debit card

First of all, you should check the state laws to see this is even legal in your state for charging a surcharge to your customers for using a debit/credit card, they vary from state to state. It’s also as part of the Intuit Payments Merchant Agreement.
Refer to #3 No Surcharge part of Merchant Agreement document:

“3. No Surcharge. You agree not to charge your customers increased fees, surcharges, or any other premiums for a Gift Card transaction, for a customer’s use of a POS terminal, or for the operation of the system unless such surcharges are permitted by applicable laws or regulations.”

Also, cash discounts are NOT legal in many states.
