Hello there, sjc3.

Let me share additional on what we can do to inform our supplier about the paid amount and balance within QuickBooks Online.

For now, QuickBooks doesn't have an option to create a vendor statement. As a workaround, we can run the Transaction List by Vendor and customize the report a bit. We can let the system generate a particular supplier as well as the paid amount and balance. 

Let me walk you through on how to do it. Here's how:

1. Go to Reports on the left panel.
2. In the search box, enter Transaction List by Vendor.
3. Click the Customize button at the upper-right corner.
4. Within the Filter section, tick the supplier you'll want to display on the report.
5. Within the Rows/Columns section, add the Open Balance.
6. Hit Run report. Also, make sure to set the correct dates.

If you want to email this one to the supplier, click the Envelope icon and select Email button. Here's the sample screenshot for additional reference:

While this option is unavailable, you may want to check our blog website to keep-up-to-date about the releasing features and enhanced ones.

Please don't hesitate to post again if you have other questions about QuickBooks. Take care and stay safe.
