One of the many growing pains in the life of a business is when owner/managers become so preoccupied with the day-to-day details of running their businesses that they become distracted from the big picture. As the old saying goes, they can "lose sight of the forest for the trees."
Another common trend is the old "E-myth" dilemma, in which owner/managers are better equipped to work IN their businesses than ON them.
Either way, there's a phase in the life cycle of any business when the it's too big for principals to handle themselves, and too small to afford quality in-house CFO personnel. That's when engaging the help of a "CFO to Go" makes all kinds of sense.
