The assumptive close is a sales technique where the salesperson acts as if the customer has already decided to make a purchase. This approach encourages the customer to agree and move forward without hesitation. By using phrases like "When would you like to start?" the salesperson creates a sense of inevitability about the sale. This method relies on the assumption that the customer is interested and ready to buy. It can be effective because it shifts the focus from objections to the next steps in the buying process. However, it requires a good understanding of the customer's needs and readiness to ensure a positive outcome.
