Marketing collateral, in sales, is the collection of media used to support the sales of a product or service. These sales aids are intended to make the salesperson's job easier and more effective. Common examples include:

• Sales brochures and other printed product information
• Posters and signs
• Visual aids used in sales presentations
• Web content
• Sales scripts
• Demonstration scripts

It differs from advertising in that it is used later in the sales cycle, usually when a prospective purchaser has been identified and sales staff are making contact with them.
