You’ve heard the one about how forgoing an expensive cup of coffee each day can add up to save thousands. It may not be much fun, but it can be a practical way to save money.

Many lawyers who keep track of the billable workday in six-minute increments can reverse this concept to describe their law practices. It goes like this: available timekeeping software does not offer simple ways to capture certain billable matters, especially client calls. Additionally, most timekeeping software does not work on multiple devices, like smartphones. As a result, attorneys often don’t input all of their time, which leads to a loss of billable hours. A few minutes here or a half-hour there adds up quickly, and before you know it, you’ve left sizable revenue on the table.
