Book To Ship Ratio Definition
The book to ship ratio refers to the proportion of the total orders shipped and billed by a company. It is a ratio that relates to demand and supply in a company, it measures the proportion or ratio of orders that a company ships for immediate delivery (which are billed). It also weighs the orders not yet shipped for delivery but already booked for future delivery.
The book to ship ratio perform certain functions such as measuring whether demand is weak or strong. It also assess the efficiency of a company in meeting and delivering orders. This ratio also quantifies the number of outstanding (pending) orders and fulfilled orders, this helps to identify problems in the supply chain and how they can be tackled.
A Little More on What is the Book To Ship Ratio
A book to ship ratio that is greater than one indicates that the company still has outstanding or pending orders. When the ratio is one, the company is efficient in the delivery of orders and a ratio less than one indicates that the company has too much goods at hand.
Quite a number of factors are responsible for each of these ratios, for instance, is a company is temporarily out of stock, orders can accumulate. A quick turnaround of a company to demand is a sign that the company is efficient while excess inventory can cause the book to ship ratio to be less than one.
The book to ship ratio can also mean book-to-bill, this ratio can be released monthly or quarterly. This ratio gives the economic outlook of a company, it is also an effective indication of rise and fall in orders and delivery. This ratio can be used in policy making.
