Hi kathyC2,
Thanks for joining us here. The Export data tool in QuickBooks Online enables you to export to Excel many reports and lists. You also have the option to download other data to your local hard drive, such as Estimates, Purchase Orders, Customer statements, Products and Services, and more. Here's an article for more details on the export system and how to export your data in the program: Export reports, lists, and other data from QuickBooks Online
At the moment, the export tool doesn't include a list of what a customer would pay. For such information, I invite you to explore the Reports menu and use the Find report by name search bar to search for reports or simply browse the list. The Customer Balance Detail report, for example, presents how much each customer owes you. Once you find a report that suits your needs, you can easily open and export it to excel using the Export icon. Feel free to check out this useful article to assist you during this process: Run reports in QuickBooks Online
I hope this helps! Don't hesitate to reach out if you have more questions.
