A business flyer is a printed advertisement used to promote a business, product, event, or service. Flyers are typically printed in full color on one or both sides of a sheet of paper, and can be distributed in various ways, such as through the mail, at trade shows, or in public places. Business flyers can be used to provide information about a business, its services or products, or to promote a special event or sale. They are an effective and affordable way to reach potential customers and build brand awareness.
