My manager provided an aging on august 31 and tracked it through sept 30. She took out some of the accounts that I had worked and was expecting payment on and added new accounts during that time frame. She said I did not reduce my receivables by 6% as was expected of me. I advised it was because she added and took receivables in my portfolio and did not adjust the receivables when calculating my my percentage of change. she says it doesn't matter if they are pulled out because it makes the numbers in the bucket zero. I say she changed the amount in the not due bucket which affected my numbers. can you add subtract receivables in the middle of the month and it not affect your numbers? How do I prove to her she is incorrect?
