About Us: E.V.S was created out of necessity to reduce the notoriously high customer turnover in the commercial cleaning industry, which by some estimates averages 50% per year. By managing in-the-field employees - especially preventing no-shows - business owners are able to drastically reduce turnover, save payroll expense, and more easily maintain existing accounts and grow their business. E.V.S works closely with commercial cleaning owners to give you everything you need and nothing you don't.
