You can try to ask Office Mate if they will create reports for you that show the date of payment and and the date of service and it will show your client how you are doing with the older balances. You can also show a comparison each month on the aging reports and that will show how your efforts are reducing the older aging. The fact that the money is increasing each month should show the improvement. If the client is questioning your efforts you may just have to show what you are doing with a daily report of dollars collected each day and MTD, claims sent, new claims sent, rejects and reasons, # of patient statements and aging worked mtd. Good luck!
