What it means
An order records what a customer wants, how much of it, at what price and by when. The same event has two names depending on which side of the desk you sit on: the buyer raises a purchase order, and the seller logs it as a sales order in their system.
Orders matter because they are the earliest reliable signal of future revenue. A sales pipeline is full of guesses, but an order is a commitment, which is why manufacturers, software firms and construction businesses all report order intake as a leading indicator alongside their reported sales.
The stock of orders received but not yet delivered is called the backlog or order book. Finance teams track it every month because a growing backlog means revenue is already banked for future periods, while a shrinking one warns that today's healthy sales figures will not repeat.
Accounting treatment is where non-finance colleagues most often get caught out. Under revenue recognition rules, an order on its own creates no revenue and no receivable; it becomes revenue when control of the goods or services passes to the customer, which may be immediately, in instalments or many months later.
A useful companion measure is the book-to-bill ratio, which compares orders received in a period with the amount actually invoiced. A ratio above 1.0 means the order book is growing, while a ratio below 1.0 means the business is delivering faster than it is selling.
In practice
Real-world examples.
Example
A commercial furniture supplier wins a $900,000 order to fit out a new hotel over eight months. The sales director celebrates, but the finance director reminds the board that only the $110,000 of desks delivered in the current month can appear in this period's revenue.
Example
A food ingredients wholesaler notices its order book has fallen for three consecutive months even though invoiced sales are at a record high. Management interprets this as a warning and slows recruitment before the delivery of existing orders runs out.
Example
A print business requires a signed purchase order before starting any job over $5,000, after a client disputed a $28,000 invoice claiming the work had only ever been discussed verbally. The policy costs a day or two of speed but removes almost all payment arguments.
Formula
Calculation
Order value = quantity ordered x unit price
Closing backlog = opening backlog + new orders received - orders fulfilled
Book-to-bill ratio = new orders received / amount billed
A specialist pump manufacturer receives an order for 500 units at $340 each, giving an order value of 500 x $340 = $170,000.
Across the whole quarter the same business starts with an opening backlog of $2,400,000, takes new orders worth $1,800,000, and delivers and invoices $1,500,000 of work. Closing backlog = $2,400,000 + $1,800,000 - $1,500,000 = $2,700,000. The book-to-bill ratio is $1,800,000 / $1,500,000 = 1.2, so the company sold $1.20 of future work for every $1.00 it delivered, and its reported revenue for the quarter is the $1,500,000 delivered, not the $1,800,000 ordered.Case study
Seen in the real world.
Bramwell Instrumentation is a fictional company invented for this illustrative example. It builds calibration equipment with a typical lead time of five months, so its order book has always been the number the board watches most closely.
In one financial year Bramwell reported record revenue of $18,400,000 and the sales team was paid a bonus accordingly. The finance director pointed out that new orders in the same year had been only $15,200,000, giving a book-to-bill ratio of about 0.83, and that the backlog had fallen from $9,000,000 to $5,800,000. In other words, the record year had been achieved by working through a queue that was not being refilled.
The board changed the commission scheme so that half the bonus was tied to orders received rather than revenue delivered. Within four quarters new orders had risen above deliveries again and the backlog began to rebuild, at the cost of a flatter reported revenue line in the transition year.
Watch out
Common mistakes.
- Announcing an order as revenue in a board pack or press update, when accounting rules require delivery before anything can be recognised.
- Ignoring the backlog and judging trading purely on invoiced sales, which hides the moment new demand starts to dry up.
- Accepting verbal orders for material amounts, leaving the business with no written evidence of quantity, price or delivery date if the customer changes their mind.
Questions
People also ask.
What is the difference between a purchase order and a sales order?
They describe the same transaction from opposite sides: the buyer issues the purchase order and the seller records it as a sales order in their own system.
Can a customer cancel an order?
Usually yes, subject to whatever the contract says about notice and cancellation charges, which is one reason a backlog is a good indicator rather than a guarantee.
Does a deposit paid with an order count as revenue?
No, cash received in advance is recorded as deferred revenue, a liability, until the goods or services are actually delivered.
