This article provides a CFO-focused guide to understanding the return on investment (ROI) of facilities management software. By reframing facilities management software as a margin-protection and cost-control tool rather than a simple operational expense, the article shows how organisations can reclaim administrative time, improve data integrity, extend asset lifecycles through preventive maintenance, and strengthen CapEx planning. A real-world case study demonstrates measurable labour-hour savings, while an ROI calculator framework helps finance leaders quantify ROI. The blog equips CFOs with practical evaluation criteria and a financial lens for modernising facilities operations.
