On the first day of a new month, Barbara reviewed the balance in her master account; it was about $2.3 million. Following her normal practice, she attempted to reconcile this against her internal sales records. She couldn't reconcile the balance against actual cash receipts because Martin's collections department handles and processes all receipt. Furthermore, Barbara had to estimate collected sales because sales collection reports were about three months behind in the system, thanks to the fact that Martin inputs all collection data into spreadsheets and forwards them only sporadically to the accounting department.
