A well-structured B2B sales funnel model will help you generate quality leads, refine the sales process, and identify and optimize customer journeys. A sales funnel is an inseparable part of the operational process, something that helps you build a sustainable strategy for new and existing customers. In order to build a successful sales funnel, you first need to understand what your customers want and then you must capture their attention. Once you’ve captured your target customers, you need to nurture those relationships to maintain that customer. And finally you must follow up regularly to receive feedback from your customers to see what needs improvement.
