Order Book

Order book means the list or value of customer orders a company has received but not yet fulfilled. In simple terms, an order book shows demand that has already been ordered but not yet delivered. Order book is important because it can help investors judge future revenue and demand strength. A strong order book may support confidence in future sales. For example, a manufacturing company with a large order book may have months or years of production already lined up. Order book is not always guaranteed revenue. Customers may cancel, delay, or change orders depending on conditions.
