What do you call a coupon or receipt book used in a naval context?

A coupon or receipt book used in a naval context is referred to as a "Chit Book." This term is used to describe a book that contains pre-printed forms or coupons, often utilized for recording transactions or requests, especially in relation to the provision of supplies or services. Chits may facilitate ordering supplies, tracking expenditures, or managing requests for resources within naval operations.

In addition to its practical use, employing a chit book helps maintain organized and accountable record-keeping, which is essential in military logistics and operations. This reduces the possibility of errors and ensures that all personnel are aware of the transactions taking place, contributing to effective communication and management within a naval unit.
