This unit explains the role of sales in generating revenue and sustaining business growth. It introduces the four stages of the sales process: identifying customer needs, presenting solutions, closing the sale, and following up to build long-term relationships. The unit emphasises that successful sales are based on understanding customer problems, delivering value, building trust, and ensuring customer satisfaction. Learners explore the relationship between sales and revenue, the importance of customer service, and strategies for encouraging repeat business and referrals. The key message is that effective sales focus on solving problems and building lasting customer relationships, not simply completing transactions.
