Consultative selling is a customer-centric sales approach that focuses on understanding customer needs and collaborating to find the best solution, rather than simply trying to make a sale. It involves taking responsibility to ensure the solution works for the customer through implementation support. The consultative selling process involves understanding the customer's business and problems, designing a customized solution, presenting the solution, and building a long-term relationship through ensuring product/service performance and quality after-sales service. Consultative selling requires thorough preparation, strong communication and problem-solving skills from salespeople.
