When you license and install an ERP software suite, you are implementing the software as it exists at that point in time. This will be the latest version (release) that is in general availability at the time that you take delivery.
The software supplier will continue to develop the system, fixing any reported problems and adding new features and functions. Most user companies pay the developer an annual maintenance and support fee, based on a percentage of the original license cost, that funds this continued development as well as support and help desk services.
