A guaranteed sale is a commitment made by a retailer or seller to ensure that a product will be sold within a specified period. This may involve offering a refund, exchange, or other incentive if the item remains unsold by a certain deadline. Guaranteed sale strategies are often used during promotional events or clearance sales to reduce excess inventory and create a sense of urgency for customers. While this tactic can help retailers manage inventory, it requires careful planning and execution to avoid potential financial risks.
