How Industrial Businesses Make Money
Industrial companies build machines, aircraft, equipment and infrastructure. Their orders arrive years before the revenue does, which changes how you read them.
Why this matters for beginners
A backlog tells you what is coming and how visible revenue is. Ignoring it means judging an industrial company on a picture that is already out of date.
Main explanation
Orders are signed long before delivery. The backlog is the value of work already won but not yet delivered, so it is the clearest signal of future revenue.
The book-to-bill ratio compares new orders with revenue delivered. Above one means the backlog is growing; below one means it is shrinking.
Aftermarket revenue from servicing, spare parts and maintenance is often steadier and more profitable than selling the original equipment.
Fixed costs are high, so factory loading matters. Long fixed-price contracts also carry cost-overrun risk that can turn a profitable order into a loss.
Example using a real company
An equipment maker sells a machine at a modest margin, then earns from servicing it for the next fifteen years at a much higher margin.
- →Book-to-bill of 1.2: orders are outpacing deliveries and the backlog grows.
- →A fixed-price contract where cost overruns wipe out the expected profit.
Common beginner mistakes
- ✕Judging an industrial company only on current revenue.
- ✕Ignoring the backlog and its quality.
- ✕Overlooking the profitability of the service business.
Key terms
- Backlog
- The value of orders won but not yet delivered.
- Book-to-bill
- New orders divided by revenue delivered in the period.
- Aftermarket
- Servicing, parts and maintenance revenue after the original sale.
Key takeaways
- 01The backlog shows future revenue visibility.
- 02Aftermarket revenue is often the more profitable half.
- 03High fixed costs and fixed-price contracts add risk.
Check yourself
- 01A book-to-bill ratio above one means the backlog is growing.
- 02Aftermarket service revenue is usually less profitable than equipment sales.
- 03Fixed-price contracts can turn unprofitable if costs overrun.
Try the concept on a real company
Study an industrial company in the Analyzer and consider how much of its value comes from servicing what it already sold.
