The most important thing to do during a ERP vendor's product demonstration is to take control of the process. In order to do that, you should create a demo script for the vendor that allows them to show you how the system handles your main requirements, step-by-step. This will give you control over the demo and the vendor will have to demonstrate how it covers the functionality that is the most important for you. Depending on the complexity of your business, be ready to spend a significant amount of time viewing vendor demonstrations.
Of course, the demo script should cover the most important processes. You should only request details when the functionality demonstrated is essential for you and your company. The demonstration is also an opportunity to evaluate each product on its qualitative aspects, such as ease-of-use. Also, don't forget to rate the product-ideally for each functionality demonstrated-so you can compare products afterwards.
