In the modern digital age, we send so many things electronically that we’re used to automatically producing a record of the transaction. However, there is still a need to send items related to the design industry — such as construction documents, specifications, samples, cuttings, etc. — physically via courier, post or shipping service. When this need arises, one uses a written document called a transmittal. This document is used to identify who is sending the item, all parties receiving it, the reason why it’s being sent, and whom to contact for questions regarding the items being sent. It’s simply a method of communication and recordkeeping.
