From Verismall Software:
Managing an internal stockroom or supply room is often a large and time-consuming problem. With this software, office products and consumables can be tracked; you can create your own database of inventory. The program was originally written for a school to keep track of stationery and books, but it can function in any kind of stockroom provided it is not used as point-of-sale software. The program allows you to store detailed information about the inventory description, vendor, location, and salesperson. It also allows you to set up a markup as a percentage of average cost (if needed) and will automatically calculate the price, total cost, markup amount, total markup, and total expected revenue.
