I need to know how much is the FEE charge for card or transfers, for the invoices that we issue to our clients

Let me share some information about the card or transfer fee in QuickBooks, @Diana2022.

If you are using a third-party merchant service for accepting credit card payments from your customers, it would be best to consult them to know the charging fee.

There are service fees that the credit card company will deduct from the payment depending on the thirty merchant services.

Additionally, you can review these articles you can utilize to card fees and manage payments in QuickBooks:
