OrderSys is a 'shopping cart' system developed in a biomedical research laboratory for day to day use by members of the laboratory. The laboratory places order through a central office for items from many different vendors. The details on the items and the vendors are stored in OrderSys, and that allows the users to quickly select items they wish to order. An order form is then generated for passing on to the office. Past orders are stored too in the system and one can follow up on placed orders. OrderSys is highly customizable and can easily be used in other settings. IP-based as well as user account-based access-restriction options are provided. The script can be customized easily with some knowledge of PHP and MySQL.
