Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How a Buyer Used Total Cost of Ownership to Cut Spend
Transcript
- Lucas: So a buyer at a mid-sized industrial pump manufacturer decided to run a total cost of ownership analysis on a major component — a high-pressure seal assembly that cost about $1.2 million a year in total spend. And here's what happened: the lower-priced supplier actually ended up costing them more over five years — about 11 percent more, to be precise — while the supplier with the higher unit price saved them eleven percent overall. Luna: Wait — so they paid more per part and still saved money overall? That sounds counterintuitive unless you're already deep in a TCO mindset. Lucas: Exactly right. And the reason most procurement teams don't get there is that their incentive structures reward beating the unit-price target. This buyer's bonus was tied to total cost reduction, which gave them the freedom to look past the sticker price. So let's walk through what they actually found. Luna: Please. I want to see the math. What went into the TCO model? Lucas: They built a five-year model with six cost buckets. The obvious one was acquisition cost — the per-unit price times expected volume. But they also included installation labor, scheduled maintenance, unscheduled downtime cost, energy consumption, and end of life disposal. Some of those are easy to estimate, some require historical data. The key was they actually had three years of maintenance records for similar seals. Luna: So Supplier A had a unit price of, say, $85 per seal, and Supplier B was $95. That $10 gap is the kind of thing a typical buyer would just flag as 'more expensive' and move on. Lucas: Right. In this case Supplier A was $82, Supplier B was $93. But the TCO analysis showed Supplier A's seals failed 40 percent more often, requiring an extra maintenance visit each year that cost $4,000 in labor and lost production. Over five years, that added up to $20,000 per unit. Supplier B's seals also consumed 15 percent less energy, saving about $1,200 per year. And disposal was simpler — less hazardous waste, so lower fees. Luna: So the higher-priced seal actually cost less over the life cycle. But that only works if the buyer has the data to model it. Most procurement teams don't track failure rates by supplier. Lucas: That's the barrier. The buyer in this case had a rare advantage: their maintenance team had been logging every seal replacement with supplier ID for years. They just hadn't shared that data with procurement. So Lucas — the buyer, not me — built a cross-functional team: maintenance, operations, accounting. That's step one for any TCO project. Luna: And what was the final decision? Did they switch suppliers? Lucas: They did. They switched to Supplier B, the $93 seal. The initial purchase price went up about 13 percent on that line item, but total cost over five years dropped 11 percent, which translated to about $660,000 in savings on a $1.2 million annual spend. The CEO was initially skeptical — he saw the higher unit cost on the P&L — but the CFO ran the numbers and confirmed the five-year net present value was positive. Luna: So the CEO's first reaction was just 'why are we paying more?' That's the exact mindset TCO has to fight against. Lucas: Exactly. And it's not irrational — if you're managing quarterly earnings, a higher unit cost hits this quarter's margin. But if you're managing total enterprise cost, you accept the short-term hit for the long-term gain. The trick is aligning incentives. This company actually changed their procurement bonus structure to include a TCO metric — 30 percent weight on unit price, 70 percent on total lifecycle cost. That's rare. Luna: I've also seen cases where TCO analysis reveals the opposite — the cheapest supplier is also the best on total cost. But teams don't do the analysis because they assume the low price is already the best deal. Lucas: Right, confirmation bias works both ways. The point is to do the math and let the data decide. Let me give a second quick example from a different buyer — this one in electronics. They were sourcing capacitors for a power supply unit. The unit price difference was tiny — three cents per capacitor — but the cheaper supplier had a defect rate of 200 parts per million versus 50 ppm. Over 10 million units, that's 1,500 more failures. And each failure in the field cost them $12 in warranty claims. The TCO swing was over $200,000. Luna: So the three-cent saving cost them eighteen grand in hidden warranty costs. That's a classic TCO finding: the cost of poor quality is often buried in a different budget line. Lucas: And that's why procurement needs to talk to quality and after-sales service. If you're only looking at the purchase order, you miss the recall risk. The buyer in the pump case told me that before the TCO project, their procurement team had no visibility into warranty data. Now they get a quarterly report from quality with supplier-level failure rates. Luna: Let me ask a practical question: if a listener wants to start a TCO analysis next week, what's the minimum viable approach? They might not have five years of data. Lucas: Start with one high-spend, high-complexity part. You don't need perfect data. Really, you need three inputs: unit price from your ERP, maintenance cost from your work order system, and failure rate from your quality team. Even if you have to estimate the failure rate based on a sample of 50 units, you'll get directional insight. Then build a simple spreadsheet with five cost categories: acquisition, installation, operation, maintenance, and disposal. Run it for three years. If the TCO difference is more than 10 percent between two suppliers, you probably have a real opportunity. Luna: And what about the supplier side? How do you get them to give you data for the model? Lucas: You don't necessarily need their data. You can use your own historicals. But if you want their input, make the TCO model part of the RFQ. Ask suppliers to provide mean time between failures, energy consumption specs, recommended maintenance intervals. You can verify some of those with third-party testing or references. The good suppliers will welcome it — it lets them differentiate on value instead of price. Luna: I've heard that some buyers share their TCO model with suppliers to get more accurate input. Is that common? Lucas: It's becoming more common in strategic sourcing. I know of a medical device company that shares a simplified TCO scorecard with all invited bidders. It shows how each cost category is weighted — for example, 40 percent price, 30 percent reliability, 20 percent lead time, 10 percent sustainability. Suppliers then self-score and provide evidence. The buyer audits the top two. That transparency actually improves trust and often leads to better proposals. Luna: So it's not about hiding the formula — it's about aligning everyone on what value means. Lucas: Exactly. And if more procurement teams did that, we'd see fewer decisions based on a three percent price cut that costs twelve percent in hidden operational drag. The pump manufacturer is now rolling TCO out to three more categories this year — motors, bearings, and control valves. They expect another $1.5 million in savings over two years. Luna: That's the kind of result that changes how the whole company thinks about procurement. It moves the function from cost center to value driver. Lucas: It really does. And I think that's the bigger lesson here. You know, if this episode moved your thinking forward in some small way, the reason we can do these deep dives without ads is listener support.

Luna: Yeah, and it's what lets us spend time on a single buyer's spreadsheet instead of rushing through headlines. So if the show's been helpful, that link is there. Lucas: Alright — last thought. The pump buyer told me one more thing. After the switch, Supplier B actually approached them with a proposal to co-invest in a redesigned seal that would last even longer. That's the kind of supplier relationship that becomes possible when you're not just grinding on price. Luna: So TCO didn't just save money — it opened the door to innovation. That's a pretty powerful outcome from a spreadsheet exercise. Lucas: Exactly. And it's repeatable. All it takes is one category, one cross-functional meeting, and the willingness to question 'the way we've always bought it.'
