Systat Software Inc Offers Many Licensing Options
Single User License: Installation of the program purchased under a Single-User License is restricted to one single personal computer owned by or under control of the licensee plus one additional computer also owned by the licensee, e.g.: one computer at home and another at work.
Site Annual License: A site annual license is another great option for multiple users who may have a smaller budget, may not have network access or do not want to use a license manager. An annual site license is like a network annual license, in that they both are good for one year.
However, depending on how many licenses you purchase, you are able to load on individual computers, as opposed to a server. So a 10 user site license can be loaded on 10 different computers and has no connection with concurrent usage.
Site Perpetual License: We also offer a perpetual plan to both the network and site licensing options. Basically the install of the network and site stay the same, but with the perpetual plan your license will NOT expire.
Most people are probably thinking, why not just go with the perpetual and not worry about it expiring? This may be a good idea if you have a larger budget and are not able to commit to an annual lower amount. You can pay the perpetual price per user and only have to deal with maintenance each year.
