One way to help you stand out from your competitors is for you to position yourself as a business partner, as someone who is always looking for ways to improve your customer's business.
Help Your Customer's Business!
When you deal with a customer, you can be fairly certain he thinks about his business day and night. It is very close to him – it’s his “baby”, so to speak, and it is close to his heart. So, if you come in and talk to him and ask him questions about his business, looking for ways to help him run it better, the customer is going to warm up to you and want to be associated with you and your company.
