Business development basically refers to the actions that a business takes to increase its revenues and grow through new opportunities that may arise from various sectors such as partnerships, markets, or services. This function of a business integrates the customer acquisition processes, i.e., marketing and sales, with customer retention and expansion via long-term planning. Business development is not about going after more leads. It is about establishing solid relationships, which will, in time, provide a steady flow of income as well as create loyalty and trust.
