Is it possible to access/view the list ID for a customer account on quickbooks desktop, or can you only query for it?

Hello, agalaura.

We appreciate your post in the Community regarding accessing the listing ID for the customer's account in QuickBooks Desktop.

Currently, this isn't possible. However, you may be able to retrieve ID by making a query request. 

To do this, I recommend getting in touch with our Intuit Developer's website and submitting your questions from there. Someone from our developer's team will respond to any questions or issue you may have. You can either log in or create a new account by visiting this page: Intuit Developer.

I'm also adding the following articles below for future reference about managing your customers, vendors, and lists in QuickBooks Desktop:

• Merge list entries in QuickBooks Desktop
• Add and edit multiple customers, vendors, and items

You can post again if you have further questions about QuickBooks. We're always available to help you.
