Good day, @ymco.

Thanks for dropping by. I’m here to provide some information about customers paying a complete statement in QuickBooks Desktop (QBDT).

At this time, customers can only pay directly through clicking the payment link on an invoice sent to them. This is available for clients who are receiving credit card payments online.  

When viewing the emailed invoice, they can click the Pay Now button and will be routed to sign in or create a login. Doing so will allow your customer to enter their account information to pay the transaction. 

Once done, the payment is downloaded and the invoice is automatically marked as paid. For more information, check out this article: Create invoices with a payment link. 

Since paying an outstanding balance through a statement using a credit card is currently not available, I’d recommend sending feedback. I’ll do the same on my end as well.

Here’s how to send product request for Merchant Services:
1.    Log in to your Merchant Services account.
2.    On the upper right-hand corner of the screen, click Feedback.
3.    Fill out the form and hit Send Feedback.

That should get you pointed in the right direction. Please let me know if you need anything else or if you have questions. I’m always here to help. Take care and have a great day!
