I love how y'all keep replying without actually addressing the issue.

I am having the same problem. I went back into my transaction history to see if I could figure it out.  I think I know the problem.  QBO used to apply ACH payments as "undeposited funds" and we could easily match it once it showed in our bank transactions.

Seemingly out of nowhere, QBO started applying ACH payments as " quick books payment bank" which pays the invoice.  But when it shows up in our bank transactions, we have nothing to match it to.  Neither the invoice nor the payment shows up as a matching option.

This is very frustrating.  Y'all keep raising your prices and making things worse.  When we tell you the exact problem, you provide copy and paste responses that don't actually answer the question.  You change things on the back end and act like the issue is on our end.
