When you purchase from TeamSys, you'll receive a license key that lets you run the applications you purchase. Your license key will only support one server so you can only purchase one copy of TeamSys Suite per order, and in most cases that's all your organization will ever need!
If you're a first time buyer, be sure to get one copy of TeamSys suite – it includes the Server program that you will need to run the system, along with a limited number of copies of the other applications. If you like, buy additional copies of the applications as your organizational needs require.
If you're a repeat customer and already have a TeamSys Server installed and you're buying additional Timers or other applications, don't buy another copy of TeamSys suite – you can't buy additional Suites and use them together for the same QuickBooks® company file (so buying two Suites is not an easy way to get an extra application for free).
