Payments
I appreciate you sharing your brilliant insight with us, @mwmwrc. I'll be glad to share a workaround on how to add credit card charges to invoices in QuickBooks Desktop (QBDT).
In QBDT, you can create a service item for the credit card fees and add it as a line item to your invoices. To do that:
- Go to Lists and click Item List.
- Select the Item dropdown, then New.
- For the Item Type, choose Service.
- Enter the Sales Price, and specify the income and expense accounts.
- Hit OK.
Once done, manually include the credit card charge as an additional line item when creating an invoice. 
We're aware of how the option to add credit card processing fees is essential to ensure accuracy in your cash flow. Since credit card surcharges are handled differently in each state, this feature is currently unavailable in QBDT.
While this option is inaccessible, I highly recommend sending our software engineers your valuable input. Doing so gives them the opportunity to review your suggestion and may consider applying it in our future product developments. To do that, go to Help, select Send Feedback Online, and click Product Suggestion.
Additionally, here's a guide if you need assistance refunding credit card payments in QBDT: Void or refund customer payments in QuickBooks Desktop.
