To be very honest this is the first time I am going to hear that marketing and sales never get along. If you really want to get consistent sales with your business it is very important for you to engage in marketing. You are going to struggle a lot as a business owner if you focus on generating sales by approaching your audience one on one. Is strong strategic marketing can help you to reduce the stress of struggling to generate sales. Is strategic marketing identified where your audience can be found in large number in came up with marketing message to attract them in mass to generate sales for you. In a not your strong marketing brings consistent sales so both of them get along.
