Can Quickbooks add the fee to the customers invoice when someone pays by credit card?

Currently, adding a credit card (CC) fee to a customer's invoice is unavailable in the program, Jeff. However, you can still include those fees by adding them as a service item. Let’s walk through the process together so you can implement this workaround.

Here's how you can do it:

1. Go to the Sales menu.
2. Choose Products & Services.
3. Click on New, then select Service.
   
   
4. Enter the name of the service item (Credit Card fee).
5. Select the account you'd use to track the processing fees.
6. Lastly, Hit Save and close.

Alternatively, you might want to consider letting your customers pay their invoices through ACH bank payments. It’s a straightforward and efficient option, and you can add a small convenience fee to cover any processing costs.
