Resource Energy Systems offers sophisticated online software called “eSAM” (Energy Site Analysis Monitoring), a proprietary mobile application specifically designed for utility calculating and reporting. Inside eSAM, utility rates are built and maintained, properties are assigned to their respective rates, and historical data is stored, all within the same application. eSAM performs all of the logic and calculations on the back end, eliminating any human calculation error. Its flexibility can accommodate many different types of tariffs and a multitude of ever-expanding reports to meet our customers’ needs. With its ability to upload and download tenant data to and from Microsoft Excel, eSAM is easy to use, accessible anywhere, and constantly being modified and maintained for optimal performance.
