Some of our software is available for a one-time license fee that will allow you to use the software as long as you like, and will include any updates released for a period of one year from your purchase date. Typically, support for software licensed in this manner is limited to whatever documentation we provide at the time of install and/or publish on our website. Any other support will probably be fee-based.
Some of our software is available on a subscription basis. This includes not only continual software updates for supported packages, but also access to online technical support.
