Eliminate Duplicates On A 1 For 1 Basis

I have a huge list of accruals and payments. Accruals (positive) are entered, and at a later date are offset by the payments (negative). Im trying to make a schedule so i can determine which are left over.

This is easy to do manually for a small amount of rows. However im dealing with 5000 rows and i do not want to manually match it would take many days to do.

Ive tried a duplicate remover. To get it to work i made an absolute value column for the negatives, and compared it to the positives column to find the duplicates. This works to a point. However, If i have three accruals for 100, and one payment for 100, all are identified as duplicates which obviously is not what im looking for.

I need to get it where one accrual is matched to one payment. if there are 3 accruals, 2 payments, 1 is not a duplicate. if there is 3 accruals, 1 payment, 2 are not duplicates.
