Direct answer: Large-office bottleless ROI depends on high water volume, multiple floors or locations, bottle handling and storage compared with installation, equipment and service costs.
Model each floor or building separately, then total the annual program. Large headcount can improve the economics, but extra dispensers, plumbing distance and service requirements can offset savings.
Build the large-site baseline
Use invoices for bottles, deposits, cooler rent, delivery fees, storage and staff handling. Include overflow purchases and different shift patterns.
Model the proposed footprint
Price every dispenser, installation, filter, sanitation and repair obligation. Compare scenarios with the bottleless cooler guide and pricing worksheet.
