3Shape offers two different billing models: LabCare Package and Basic Package. In addition to free support and training, the larger LabCare package also includes regular software upgrades. With the Basic package, labs have to pay for support, and the paid version of the software remains permanent.
Billing at exocad is similar. The Flex license roughly corresponds to the 3Shape LabCare package. Users have access to regular updates here. However, there is also the option of booking a permanent license that does not require the installation of updates – at least not as long as the exocad software and the operating system are compatible. In the event that the design software and operating system no longer work together, exocad offers an upgrade contract that can be canceled at any time at no additional cost. In principle, it is also possible to buy the permanent license without the upgrade contract. Should this become necessary at a later point in time, there is the option of catching up on missed updates with a refresh program, which is priced individually.
