A summary close is a sales technique used to reinforce the benefits of a product or service before asking for a decision. It involves briefly recapping the key points discussed during the conversation, highlighting how the offering meets the customer's needs. This method helps to clarify any remaining doubts and solidifies the value proposition. By summarizing the main advantages, the salesperson can create a sense of urgency and encourage the customer to take action. This approach is effective in various sales contexts, including B2B sales, real estate, and retail, as it helps to guide the customer toward making a purchase decision.
