Principles of Marketing Marketing is the part of your business where money is made. In order to succeed in business, the following two principles of marketing should be kept in mind. First, customers are the mainstay of any business. Attracting customers to a business makes the difference between succeeding and failing.

If customers are satisfied, there is a chance that they will be retained for a long time and possibly permanently. Undoubtedly they are likely to talk to other potential customers. Another principle for a business is that profitable sales volume is more important than maximum sales volume.
