Introduction
Three quotes sit on the table, for three machines that do the same job. One is clearly cheaper. Everyone congratulates themselves on the saving, the purchase order goes out, and the matter is closed.
Then the machine arrives. It uses more power than the others would have. Its spare parts come from a single supplier on another continent. Changeovers take longer, and scrap that never reached the spreadsheet piles up beside the line. Per a U.S. Department of Energy figure cited by Pumps & Systems, power alone accounts for nearly 88 percent of a compressor's ten-year life-span cost. That leaves very little room for the purchase price to be the number that matters.
In this article, we'll look at why the price tag is the smallest number attached to any machine, where the saving actually goes, and three steps any team can start this week.
The Two Prices of Every Machine
Every machine has two prices. The first is the one printed on the quote. The second is everything you pay after the invoice is settled: energy, downtime, spare parts, changeovers, scrap, and the hours someone spends nursing it through each shift.
The first price is the smallest number on the machine. The second is the one that matters, and it is almost never on the tender document.
The First Price vs. the Second Price
| Aspect | First price | Second price |
|---|---|---|
| What it covers | Purchase price on the quote | Energy, downtime, spares, changeovers, scrap, labor |
| When it is paid | Once, on the day of the order | Every shift for the life of the machine |
| Who sees it | Everyone in the tender | Mostly the people running the machine |
Where the Saving Disappears
The saving on a cheap machine is real on the day of the purchase order. After that, it is fictional every day. Nobody goes back to compare the tender price with the next ten years of bills, so the mistake never shows up as a mistake. It shows up as a line item called "operating cost," spread thinly enough that no single month looks wrong.
"A cheaper machine that stops twice as often is not cheaper. It is just cheaper on the day you sign."
The same pattern sits behind the losses we describe in how a $1.2M annual loss went unnoticed: each cost is small in isolation, owned by nobody, and invisible in any single department's report.
What Deming Said About the Price Tag
W. Edwards Deming put this in writing as the fourth of his fourteen points for management: end the practice of awarding business on the basis of price tag, and instead minimize total cost. His rule was that purchase price plus everything after it is the number to compare.
Most tenders still do the opposite. They compare three numbers on day one and ignore ten years of bills.
Strategies for Buying on Total Cost
1. Price Ten Years, Not Day One
For your next purchase, ask every supplier for the numbers that make up the second price, in writing, before the quotes are compared.
What to Ask For
- Power use: rated consumption at your real duty cycle, not a brochure figure.
- Spare-part prices and lead times: including which parts come from a single source.
- Changeover time: how long it takes to switch products, with a reference customer who will confirm it.
2. Ask the Team Running the Last Cheap Machine
Call the people running the last cheap machine you bought and ask what it really cost. Write the number down. That number becomes your tender template from now on, because it replaces an estimate with a measured result from your own plant.
3. Make the Buyer Sign the Running Cost
Whoever picks the machine owns its bills for the next five years. When the person approving the purchase also signs off on the running cost, the second price stops being somebody else's problem.
A Ten-Year Comparison Template
| Cost line | Where the number comes from |
|---|---|
| Purchase price | The quote |
| Energy per year | Supplier's written power figure, checked against a reference site |
| Spare parts and wait time | Spares price list and stated lead times |
| Changeover time | Written figure plus a customer who will confirm it |
| Scrap and rework | Your own data from the last similar machine |
| Operator and maintenance hours | The team running the comparable machine today |
Real-Life Case Studies
Case Study 1: Deming's Fourth Point
Deming's rule is the clearest statement of the idea in management literature. Its fourteen points treat price as one input to a decision about quality and total cost, never as the decision itself. The argument has aged well because it is arithmetic, not opinion.
Case Study 2: The Compressed Air System
Compressed air shows how lopsided the two prices can be. The Department of Energy figure quoted above puts power at nearly 88 percent of a compressor's ten-year cost. The purchase price, the part every tender compares, is a small slice of what the machine will cost to own.
Case Study 3: What We See in Our Own Work
Across engagements in ten industries and four continents, we see the same result: teams that buy on full cost argue less about machines, because the running-cost numbers settle the argument before it starts. It is the same discipline behind our financial turnaround and process improvement work.
Key Takeaways
- Every machine has two prices, and the one on the quote is the smaller one.
- A saving on the purchase order can turn negative within months once energy, spares, changeovers and scrap are counted.
- Ask suppliers for power use, spare-part prices and changeover time in writing, and price ten years instead of day one.
- Use the measured cost of your last cheap machine as the template for the next tender.
- Make whoever picks the machine sign for its running cost.
FAQ Section
Q: What is total cost of ownership?
A: It is the full cost of an asset over its working life: the purchase price plus energy,
maintenance, spare parts, downtime, changeovers, scrap, and the labor spent keeping it
running.
Q: How many years should we price?
A: Match the horizon to the asset's realistic working life. Ten years is a common horizon for
production machines. A shorter horizon works for equipment that will be replaced sooner, as
long as every quote is priced over the same period.
Q: What if a supplier won't give running-cost figures?
A: Treat that as information. Ask for power rating, spare-part prices, and changeover time in
writing, and compare them with what existing customers report. A supplier who cannot state
these numbers is asking you to carry the risk.
Q: Is the cheapest quote ever the right choice?
A: Yes, when running costs are similar or the machine will be replaced quickly. The point is
to check the second price before deciding, not to always pick the expensive option.
Conclusion
Back to those three quotes. The cheapest one won and nobody checked what it would cost to own. The saving lasted one day, and the bills ran for ten years. The test is simple: add up what the cheap machine really cost, then look at the one you thought was too expensive.
