I have a client who connected a 3rd party app/program to QuickBooks desktop.
That app is for tracking customers and income.
The journal entries that the app was set up to send to QuickBooks desktop are as follows:
(1)  Accounts Receivable $XX debit
                                   Income $XX credit
(2)  Cash/Undeposited Funds, etc. $XX debit
                                        Accounts Receivable $XX credit
These entries have been sent to QuickBooks daily for years.
PROBLEM: the credits to Accounts Receivable have never been applied to the debits.
So the Open Invoices report has hundreds and hundreds of journal entries listed (that basically net out to zero).
How can we get them applied without clicking on every single individual payment and applying it LINE BY LINE in the Customer/Receive Payments screen?
