A business letterhead is a pre-printed heading on documents like letters, memos, and notes. Including one will make any document look professional and help keep your branding consistent. Letterhead is usually comprised of the corporate logo, address and contact details. It generally has a matching envelope.
A letterhead is as important as a brand, in that it represents a corporate and can impart a first impression to its potential customers. This makes it a critical component of business correspondence, but it also means that not just any letterhead will do. You can also make your own letterhead that holds up to the top designers, without the hassle of hiring one.
