Presale is a method used to validate if customers will purchase your product or service. It involves taking orders before a product or service has been made available.   To prepare for a presale, you need to identify your target customer segment and determine how you will offer the presale. Then, you should create the sales assets you will need, such as a sales page, brochure, or presentation.   To execute a presale, you should present your offer to your target audience and collect orders. You should track how many customers purchased and gather feedback from them. Finally, you should analyze the results to determine if there is sufficient demand for your product or service.
