Why it matters at exit
A buyer is paying for profits that carry on after you have gone, so anything that leaves with you lowers what they will offer. If you hold the main customer relationships, approve every quote, or are the only person who understands how the work actually gets done, a buyer sees a genuine risk that revenue falls once you exit. That risk usually shows up in three ways: a lower multiple applied to your profits, a larger share of the price deferred into an earn-out, or a requirement that you stay on for two or three years after completion. Reducing owner dependency in the years before a sale, by delegating relationships, building a management layer and writing down how things are done, is one of the few changes that both raises the price and gives you a cleaner exit.
