On each of those 15 days 3 of the social agency's children were serviced. The social agency has not sent the payment yet. (April 30th) Agreed to provide service for an social service agency at a daily rate of 25$/child w/ payment due on the 30th of each month. OK I know that I will be Debiting 1,125 and Crediting 1,125 but I don't know in which account please help!
