You want new customers, of course. New customers allow you to make more money. But serving new customers can be a real pain in the rear. It puts a strain on your staff. As workloads get heavier, performance will start to slip. Eventually, you’ll reach the point where you won’t be able to serve more customers unless you hire more employees. Hiring more employees is expensive. In addition to adding another salary to your payroll, it also puts you on the hook for more taxes, benefits, and other costs. This might be too expensive for you to handle. Especially if you run a courier company or some other business that depends on drivers. Adding a new driver to your staff would mean you’d have to pay for more gas and vehicle maintenance.
