I can see the importance of this feature on your end, . Let me chime in on this conversation to provide information about invoice payments in QuickBooks Online (QBO).

When using QBO, the system will only rely on the data that has been downloaded from an external source. This is because the mapping does not have an online payment option, and the option to enable this feature is not available when uploading data. Therefore, you will need to manually turn on the online payments option once the invoice has been uploaded.

Moreover, I'm adding this helpful article as your reference in run basic reports in QBO: Run reports in QuickBooks Online.

Don't hesitate to return to this post if you have other concerns about your invoice payments in QBO. I'll be here to lend a hand.
