Since the early 90s, most large companies have made the choice to implement an Enterprise Resource Planning (ERP) system. In short, the purpose of an ERP is to link together the data from the various functions of the company so that they can be leveraged to the company's advantage. For example, if the sales team has real time access to inventory levels, they can make real-time decisions about which products to push harder. The advent of web based ERP, with it's lower cost and simpler implementation, has pushed adoption further, with many mid-sized businesses now reaping the same benefits as the big boys. This raises of the question of whether an ERP might have benefits for a truly small business.
