Facility management software typically has a strong ROI, especially for multi-location businesses whose facilities programs have previously been run on pen-and-paper. Oftentimes, the savings brought about solely by switching to electronic payment processing (as opposed to manual invoicing) is enough to offset the cost of a facility management platform and then some. To estimate potential ROI for facilities management software, multiply your total annual maintenance expense by the total annual savings percentage expected as a result of the software implementation. This value represents your total annual efficiency savings. Subtract the cost of the FM software from the total annual efficiency savings to determine total annual ROI savings.
