Imagine that you are working with a small business owner who has been doing his own bookkeeping up until now. As his business has grown, however, he is now so busy with work that he has asked his brother to handle the accounts payable side of the business. To help him out, he has put together the following narrative of the process: After the supplier sends us an invoice, I verify it for correctness against my purchase order file. If it is correct, I place it in the shoe box marked "To Be Paid". On Fridays, I select all of the currently due invoices from the shoe box and prepare cheques. I update the cheque register with the cheque details and send the cheque to the supplier. At the end of the month, I reconcile my cheque register with the statement that the bank has sent me. Create a context diagram and a level 0 DFD for the accounts payable system. It is recommended that you create the diagrams in PowerPoint.
