A business letterhead is a printed heading at the top of a company's official documents, such as letters and invoices. It typically includes the company's name, logo, address, phone number, email, and website. This design element helps to establish the company's identity and provides essential contact information in a professional format. Using a letterhead enhances the credibility of the communication and ensures consistency across all official correspondence. It is often customized to reflect the company's branding, making it easily recognizable to clients and partners. A well-designed letterhead can leave a positive impression and reinforce the company's image.
