Problem:
Megagrocer is a grocery chain that operates five stores. The stores are supplied with produce, meat, dairy, and dry goods by six separate vendors. In addition to the stores, Megagrocer maintains an e-commerce site through which customers can order and pay for groceries. The groceries are packed and delivered to customers from one of the five stores in a Megagrocer van by that store's personnel. Think about the accounting information systems that Megagrocer might use.
o What types of source documents might be collected by Megagrocer to be processed by its accounting information systems?
o Why are those documents important?
