Sales is about executing a transaction while marketing is about communication. The biggest mistake many companies make is confusing sales and marketing as the same thing. They both have different goals and objectives that require different methods and techniques to be effective. For sales, the goal is to generate revenue, while marketing is to inform and educate.
Sales growth is very dependent on an effective marketing strategy since sales consists of individual transactions, while marketing can be broadcasted to a large audience. Marketing efforts should attract or gather potential customers to be funneled to the sales team.
