Required information Beach Cities Rentals rents almost anything. They rent tools, equipment, trucks for everything from home remodeling projects to major construction projects. They also rent office equipment, such as desks, file cabinets, chairs, tables, and office dcor items. Finally, they rent furniture for short term home staging or long-term use. They have become well known in the area for having what their customers want. Construction companies, contractors, real estate agents, office managers, and individual homeowners and renters all rely on Beach Cities to have what they need in stock. The following case describes Beach Cities' processes for purchasing new inventory from its suppliers. Rental inventory and inventory categories Beach Cities keeps all items available for rent in one inventory class, although it categorizes its inventory by the type of inventory. Each inventory item is identified internally by the inventory number (inventory #). The inventory category # serves as Beach Cities catalog number for its catalog and website. For example, Beach Cities catalog could list executive desk chairs (category number 420), but internally it tracks each desk chair in inventory. Since its inventory is so extensive, it stores much of the inventory in its various storage lots. Beach Cities tracks its various storage lots by storage lot #. Replacing rental inventory Beach Cities replaces its inventory items as soon as they show signs of wear and tear. The Beach City buyer issues purchase orders to its suppliers and then a Beach City receiving employee records the date that item was received into inventory. It pays suppliers in full by check within 30 days after receipt of the items. Since each purchase order results in one receipt of items, Beach Cities keeps the purchase order and purchases information in one class. Each purchase can involve many inventory items, but each item is only purchased once. Beach Cities tracks the buying employee as well as the receiving employee for each purchase order/purchase.
