The job: renewing contracts on purpose
How it usually goes
Annual maintenance contracts renew in one of two ways. Either an account manager remembers, or a client calls to ask why an engineer has not arrived. The second version is expensive, because the renewal is then negotiated from a position of apology, and because a lapsed month is rarely recovered in billing.
The tracker exists so that renewal is a scheduled piece of work with an owner, a starting number and a deadline that comes from the notice period rather than from somebody's memory. For most service firms the contract book is the most predictable revenue they have, and it is usually the least managed.
