Hi @SKSLandCo.

Welcome to the Community! I’m glad you found us. Adding credit card fees automatically when a customer pays their invoice by credit card or ACH would be a great option. Currently, this feature isn’t available in QuickBooks.

You could charge your customer the credit card processing fee by adding it to their invoice.

You would set up a service item for the fee. Here's how:

1. Go to Sales then choose Products and Services.
2. Click on New then select Service.
3. Enter the name of your service item. (Example CC Fee)
4. Select the account you'd use to track our processing fees under the Income account drop-down.
5. Once done, click Save and Close.

Then you would add the service item to the invoice.

Here is some additional information about credit card processing.

Let me know if you have any additional questions about processing fees or anything else. I’m here to help any time.

Have a great day!
