How capital goods companies report results: order book, revenue recognition and margins explained

A capital goods or industrial manufacturer — turbines, machinery, engineering and construction equipment — often builds large, custom orders that take months or years to complete. That changes what shows up in its results: alongside revenue and profit, these companies report on the pipeline of work they are executing, not just what they have already delivered.

Order inflow and order book

• Order inflow (also called order booking or order intake): the value of new orders won and confirmed during the period.
• Order book (or order backlog): the total value of confirmed orders not yet executed, at a point in time. It rolls forward: opening order book, plus order inflow, minus revenue executed (billed) in the period, gives the closing order book.
• Book-to-bill ratio: order inflow for the period divided by revenue recognised in the same period. Above 1 means the company won more new business than it executed, so the order book is growing; below 1 means it is drawing the order book down.

The order book is often described in months or years of revenue “cover” — dividing the order book by a recent run-rate of revenue — as a rough sense of how much confirmed work is ahead of the company. It is not a promise that every order will be executed on the same terms or timeline originally agreed.

How revenue is recognised

Unlike a retailer or a fast-moving-goods company, where a sale and delivery happen close together, a capital goods company can spend a long time building one order. Under Ind AS 115 (the accounting standard for revenue from contracts with customers), a performance obligation can be recognised over time as work progresses — measured by an input method (such as costs incurred so far) or an output method (such as units produced or milestones completed) — rather than only when the finished item is delivered. This is why revenue in a given quarter reflects execution progress on the order book, not just new orders signed that quarter.

Margins and mix

• EBITDA margin: EBITDA as a share of revenue. It moves with the mix of orders being executed (export versus domestic, original equipment versus spares/aftermarket service, and the pricing locked in when each order was originally won, which may predate the quarter it is executed in).
• Aftermarket / services revenue: revenue from spares, servicing and upgrades on equipment already sold, as distinct from new equipment. It typically carries a different margin profile from new-order execution and is often reported separately.

An illustrative example

A fictional capital goods manufacturer, in ₹ crore, for one quarter:

	This year	Last year
Opening order book	2,000	n/a
Order inflow	600	550
Revenue (executed)	450	400
Closing order book	2,150	n/a
Book-to-bill ratio	1.33	n/a
EBITDA	81	96
EBITDA margin	18.0%	24.0%

Order inflow rose year on year (600 against 550, about +9.1%) and the order book grew, since the company won more work than it executed (book-to-bill above 1). At the same time EBITDA margin narrowed. Reading the order book and the margin together, rather than either alone, shows whether growth in the pipeline is coming through at the same profitability as before.

What can move the numbers without changing the underlying business

A single large order can swing order inflow and the order book sharply between quarters, since these companies deal in fewer, bigger contracts than a retailer would. Currency movements can also affect export orders and revenue. Reading more than one quarter, and reading what the company itself says drove any large change, gives a fuller picture than one quarter’s figures alone.
