Be careful to ask for full copies, not a subset of the total functionality. Your testing should provide a comprehensive sense of the software's capabilities. If a demonstration area isn't readily visible, ask if one is available. Some Extras are Essential - Software buyers are often taken in by the bells and whistles and end up buying functions they don t need, at the expense of necessary services. Don't overlook the importance of training and support services.
Many vendors offer annual maintenance contracts for support and upgrades.
These are generally worth the money. And unless you are purchasing familiar software, it pays to purchase available training also. What you spend for training a small number of people will be repaid threefold in time and ease of application. Be advised, however, that development efforts often take longer and cost more than projected. After the system has been installed and the users are trained, don t be surprised if your procedures and practices also change.
