Hello there, dennynguyen.

Allow me to share with you some information about processing fees in QuickBooks. 

If you sign up for Merchant Services or QuickBooks Payments and process payments, you will incur processing fees each time a customer pays an invoice. These charges vary depending on how you processed the payment. Here's a link to our website for the updated fees: Standard Payment Fees & Rates.

I've also added this article as an additional resource if want to make sure that your payments and processing fees will be recorded to the correct accounts: Choose where to record payments and processing fees for QuickBooks Payments.

Leave a comment below if you have follow-up questions about processing payments. I'm always here to help. Have a great day!
