It's good to have you here, Sandra.

I can share some insights about this statements concern in QuickBooks Online. 

If you want to send overdue statements, make sure to filter the Customer Balance Status to Overdue. This way, only overdue transactions are included on the statement, not the other entries that are not past due.

Post here anytime if you have any other concerns with this topic. I'll be more than happy to help. Have a good one!
