Option A The mailroom receives orders from customers (Customer Order). Each order is stamped with the date it was received. Next it is sent to the Sales Department. Salesclerk \#1 fills out a 2 part sales order using the customer order, the customer sheet from the paper customer file (where it was filed alphabetically), inventory availability and prices from the current (and/or specials) inventory 3 ring binder, and credit approval from the current A/R subsidiary ledger. (The binder and the subsidiary ledger stay with Salesclerk \#1, and only information is transferred from them to the Sales Order.) The customer sheet is re-filed in the customer file. Salesclerk \#2 reviews the Sales Order and Customer Order and sends copy 1 of the Sales Order to the Warehouse, where it is filed chronologically. [Process would continue from here, but we are pausing.] The Customer Order is attached to Sales Order (2) and filed in the Sales Order paper file in numerical order, by sales order number. Option B (The company has installed a computerized AIS) The mailroom receives orders from customers (Customer Order). Each order is stamped with the date it was received. Next it is sent to the Sales Department. Sales clerk \#1 inputs the sales order details into the online system from the customer's order. The computer uses the customer master file for account data, determines inventory availability and prices (inventory master file), and grants credit approval based on account status in the A/R master file. A sales order transaction record is created in the Sales Order file and the sales order is printed in the Warehouse. [Process would continue from here, but we are pausing.] The Customer Order is filed numerically. The Sales Order is filed alphabetically by customer in the Warehouse
