Superb customer service can not only win you customers it can also help you retain the new customers who might also refer new customers your way. So offering better customers service than your competitors will be good for your business. A great way to offer better customer service than your competitors is by staying in touch with customers long after you sell them something. Few businesses do that. Find out if they are having difficulties using a product you sold them, whether they were satisfied with the product they bought, etc. Do this often and there's a high likelihood that many of these customers will buy more products from you in future.
