You need to have a 3rd party payment processor to do so.

Automatically adding a credit card surcharge to transactions in QuickBooks Payments is unavailable, redrockfence. Instead, you can manually calculate the fee and include it as a separate line item on your invoice or sales receipt.

If you haven't created a service item, follow the steps below:

1. Click My Apps and select Sales & Get Paid.
2. Choose Product & Service.
3. Click on the New button, then select Service.
4. Enter the name of your service item. (Example CC Fee)
5. Select the account you'd use to track the processing fees.
6. Once done, click Save and Close.
   

After creating the service item, you can add the credit card fee as an additional line item on your invoices whenever you charge your customers a processing fee. I'll be sharing a sample invoice breakdown for you:

1. Percentage fee:2.9% of $1,000 = $29.00
2. Flat fee: $0.30
3. Total fee: $29.00 + $0.30 = $29.30

• Line 1: Invoice amount for goods or services: $1,000
• Line 2: Credit card processing fee: $29.30
  • Description: Credit card processing fee (2.9% + $0.30)
