At this time, being able to import customers' payments in QuickBooks Online using an Excel file isn't available. The program only allows you to import Excel files for bank transactions and lists.

I can see the convenience of having the option to import payments in QBO. Know that our developers are always gathering and considering new features to be added in the program to cope with our customers' needs.
I'd encourage you to visit our QuickBooks Online Blog site regularly to be updated with our news and product enhancements.

Let me know if you have any other questions or concern. I'll be around to lend a helping hand. Have a good one!
