Reinvesting in the business without overdoing it
Reinvestment grows shops. Over-reinvestment starves them. The line is real.
Pick a reinvestment budget annually
A dollar amount or percentage of profit allocated to equipment, training, marketing, hiring. Calendar it. Random reinvestment chooses what's loudest, not what's best.
Bias toward higher-leverage investments
A new estimator, a route-optimization tool, a sales training course can outperform a new truck. Don't reinvest into more capacity if utilization isn't there yet.
Take some off the table too
Personal savings, retirement, emergency fund. Reinvesting 100% of profit into the business is a strategy that ages poorly.
