Expanding is expensive. You need to hire more drivers, get more vehicles, and spend more on fuel. When you hire a new driver, you’ll be on the hook for more than just a salary. There’s also training, benefits, and other costs to consider. And when you buy a new vehicle, in addition to the cost of the car itself, you also need to pay for repair bills, registration fees, and other expenses. But if you run a small business with a thin profit margin, you probably can’t afford to take on all those expenses.
