Thanks for posting in the Community space, @mary-larson.
When it comes to using third-party apps, QuickBooks Online (QBO) doesn't control how the items and transactions are transported in. We only receive and record the data on the system.
To ensure that the transactions will sync to QBO, I'd recommend contacting our Online Bill Pay Customer Care Support. They can review the connection setup between Online Pay Bill and QBO and help you get back on track.
To know more about how Online Bill Pay works, see below helpful links:
If you have additional questions about QuickBooks, let me know, and I'll get back to you. Have a great day.
