Managing a profitable company is all about controlling costs enough that revenues outpace expenses and margins are strong enough to weather slower sales. For many businesses, this cost-control starts with basic, universal costs, such as employee wages and space rental. But you need to dig deeper. In addition to the standard overhead expenses that every firm experiences, there are a range of other expenses that are more dynamic and variant than bills like utilities. These expenses are known as the “Three T’s” and they include telecom, travel and technology costs.
