A sales deck is a presentation that salespeople use to sell products or services to potential customers. A typical sales deck includes slides with information about the product or service, the company, the market, and the competition. Salespeople use sales decks to persuade potential customers to buy their products or services. The term "sales deck" can also refer to the software that salespeople use to create presentations, such as PowerPoint or Keynote. Sales decks are often created using templates so that they can be easily customized for each customer.
