I'm a bit surprised by some of the responses to this post. I think all solo operators, if they are successful, eventually find themselves in a position where something has to give. Age, changing family structure, health, the economy, are all factors that can, over time, change not only your need for accounts, but also your ability to maintain quality service for all your customers. Logic dictates that the first accounts to go should be the least profitable, and/or, most physically demanding. That is pretty much a no-brainer.
Just be honest. Tell them your business has grown to the point where you can no longer service all your properties and maintain the level of excellence you demand of yourself, so you must reluctantly drop some accounts from your schedule. Thank them profusely for their business and support, and, if you can, refer them to someone else.
