Adopting this belief means you need to become much more selective about who you do business with, even though that marginal business may be “profitable” by conventional accounting standards. Very often the most important costs—and benefits, for that matter—do not ever show up on a profit and loss statement. Accepting customers who are not a good fit for your firm—either because of their personality or the nature of the work involved—has many deleterious effects, such as negatively affecting team member morale, and committing fixed capacity to customers who do not value your offerings. This is why the new equation focuses on profitability, not simply gross revenue. When it comes to customers, less is usually more.
