Service businesses cover all kinds of work—cleaning, fixing things, consulting, marketing, design, you name it. What makes them work? Being good at your job, people trusting you, and doing what you say you’ll do. Doesn’t matter if you work for regular folks or businesses; just do good work and keep people happy. How you price things, when you show up, and how you talk to people all add up to what people think about you.
A business plan keeps you organized. It helps you figure out where to spend your time and money, and what you want down the line. It tells you how to find customers who are right for you, how to work faster without cutting corners, and how to build something people can rely on that puts money in your pocket.
