A sales lead is the identification of a person or organization that has, for the interest and authority to purchase a product or service. This step represents the first stage of a sales process. Lead can be associated with a company or business (B2B advantage) with the person (s). The drivers are generic leads – ie a person signs up for a type of offer, instead of a particular company or brand. Sales leads come from either process of lead generation companies, such as trade shows, direct marketing, advertising, Internet marketing, spam, gimmicks, or from sales person prospecting activities such as cold calling. For a customer order to qualify as a prospectus, or equivalent, to move a lead from the process step sales lead to the process leading brochure, qualification must be performed and evaluated. Usually, the determination includes managing product applicability, availability of funding and timelines for purchase by direct questioning. This is also the beginning of a tunnel sales, sales funnel flow or sales.
