About Us

The original PRA (Property Reserve Analysis) System was designed in 1988/1989 as a multi-faceted asset management tool (physical and financial). Prior to the PRA System only spreadsheets or paper and pencil were used to perform the task at hand. It could be utilized in any scenario where the long-term maintenance or replacement of real or personal property existed (i.e. common interest developments (wholly owned condominiums and timeshare), hotels, golf courses, commercial property, etc.)). It afforded the user the ability to efficiently budget and schedule for long-term maintenance and replacement of real and personal property, while accurately formulating a financial plan. In 1992 the system introduced cash management, the planning of investment of funds for maximization of return and producing cash availability reports based upon a budgeted cash flow. The system followed the guidelines set for financial forecasting and projecting by the American Institute of CPAs (AICPA). The PRA system was not developed to dictate how a reserve analysis or study should be prepared or calculated, but supplied the user with the capabilities for creating plans in which to produce a customized analysis and report tailored to meet desired specific needs.

The first version of the PRA System was developed in April, 1989. The system wasn't much more than a simplistic, user-friendly, menu-driven database software, but it got the job done. In the beginning of 1989, PC software applications were still working within the 640 K conventional memory limitations and the 286-20mghz processors were state-of-the-art. As the system was further developed and became more dimensional to meet user's true needs, it became obvious why this product had not been developed before. Due to the complexity of the program and the potential size of the data bases, PC hardware and software was not available in the eighties to meet the challenges of the PRA System. The concepts of the system would have only been available in a mainframe environment, which would have made hardware costs prohibitive for the potential small user. When the 640K conventional memory barrier was eliminated and with the development of faster processors, the system was able to progress as planned.

The original DOS version of the PRA System ceased development of any new features and reports in December, 1995. The system continued to be licensed until 2005. Original users have continued to use this system until being recently updated with the next generation of the PRA System. As the original 1989 DOS system was on the cutting edge of technology, the new PRA System is once again state-of-the-art with many new features, navigation and reports. With the multi-site, multi-property tracking capabilities, quantity purchasing reports can now be produced. The system is now a Windows, Internet based system utilizing Microsoft.Net, Microsoft SQL and WestWind technologies.
