POSSE product upgrades are provided to the Client as part of the annual POSSE Product SaaS or Annual Maintenance fee. For each new product release, Computronix Product Support will notify the Client of a coming release and provide preliminary documentation such as Version Release Notes and/or a Features Update detailing what is new and what has been fixed in the release. Each POSSE release, regardless of type, provides adequate documentation for the Client to upgrade the POSSE application. Approximately half of Computronix customers perform their own upgrades, depending upon the POSSE technical experience, size of the IT staff, and type of release.
