All we had to do was purchase the software and several licenses and see how we liked it. We could do the implementation ourselves, at our pace. Overall, xTuple gave us alternatives that no other vendor could.
If I'm an annual license customer, how does support and maintenance work?
Software maintenance - access to all upgrades, major and minor - is included in the annual license. The annual license is like a subscription. You are licensed to use the software as long as you are current on your payments (either annual or monthly). If you're more than 30 days late, you could be in default of your license and support agreements.
