Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How One Buyer Used Reverse Auctions to Cut Spend 30 Percent
Transcript
- Lucas: So you've probably heard the term reverse auction thrown around in procurement circles, and maybe you've got a mental image of suppliers frantically lowering their prices in real time while a buyer watches the numbers drop. That does happen, but the most interesting reverse auction stories are the ones where the buyer doesn't just smash the price down—they use the process to fundamentally rewire a supplier relationship. Luna: And today's episode is one of those? I'm guessing we're not talking about a commodity like copy paper. Lucas: No, not at all. Today it's MRO—maintenance, repair, and operations supplies. Think pumps, valves, gaskets, filters, belts. The kind of stuff that keeps a factory running, but that nobody in procurement really loves to think about because it's fragmented and often low-visibility. The buyer we're following—I'll call her Sarah—works at a mid-sized industrial manufacturer with about a dozen plants across the Midwest. She was looking at an MRO spend of about two point eight million dollars, and the incumbent suppliers had held that business for over a decade. Prices were going up about twelve percent year over year, mostly through annual price increases that nobody pushed back on. Luna: Classic tail-spend neglect. So she decides to run a reverse auction—but how does she even get suppliers to participate when they know they're being squeezed? Lucas: That's the critical question, and Sarah handled it really carefully. She didn't just send out an RFP to the incumbents and a few randoms. She did a full pre-qualification round—financial stability, quality certifications, on-time delivery track record, ability to service all twelve plants. She ended up with five qualified bidders. Then she spent a month sharing detailed spend data with each of them, so they could see the volume and the mix. She wanted them to come to the auction knowing exactly what they were bidding on—no surprises. Luna: So transparency on her side to build trust. But the incumbents must have hated this. They were about to lose a sweetheart deal. Lucas: They did. One incumbent told her they'd never participated in a reverse auction before and that they felt it was disrespectful. Sarah's response was—and I think this is key—she said, 'I respect your position, but my job is to deliver value to my company. You've had this business for twelve years without a competitive check. This is me doing my job.' She didn't apologise. She didn't back down. She just framed it as a normal business process. Luna: I like that. So the auction day comes—how does she structure the event itself? Lucas: She chose a sealed-bid format, not a live descending clock. Here's why: MRO categories are broad. You might be bidding on a thousand line items, and the suppliers don't all have the same cost structure for different sub-categories. A live auction with everyone watching the total price drop can lead to panic bidding, mistakes, or suppliers dropping out early. Sealed bid means each supplier submits their best offer on the entire basket of items, and they only get one shot. Sarah set the bid window for forty-eight hours, which gave them time to really work through their costs. Luna: And the result? I'm guessing it worked well if you're telling the story. Lucas: It worked spectacularly. The winning bid came in at thirty percent below the current spend. That's about eight hundred and forty thousand dollars in annual savings. And the winning supplier wasn't an incumbent—it was a regional distributor who had never worked with Sarah's company before. They had lower overhead, a more efficient logistics network, and they really wanted the account. Luna: Thirty percent is huge. But I have to ask—did the savings come from the supplier cutting their margin to zero? Because that's not sustainable. Lucas: Great question, and Sarah asked the same thing. Post-auction, she did a full should-cost analysis with the winner. She visited their warehouse, reviewed their labor costs, their transportation routes. And what she found was that the incumbents had been padding their margins for years because they could. The winning supplier had a leaner operation and was willing to price at a fair margin—around eight percent. So the savings were real, not just a one-time margin squeeze. Luna: But if the incumbent had been padding margins for a decade, why didn't Sarah's predecessors ever push back? Lucas: Because MRO was nobody's priority. It was spread across plant managers ordering stuff locally, no central visibility, no data. Sarah spent her first six months just building a spend cube—aggregating all that fragmented data into one view. Once she had the two point eight million number on a single spreadsheet, she had a mandate. That's the prerequisite for any reverse auction: you need clean data. Luna: So the auction is over, new supplier is in place—then what? How did the transition go? Because switching MRO suppliers across twelve plants sounds like a logistical nightmare. Lucas: It was. And this is where Sarah's planning paid off again. She negotiated a ninety-day phased transition in the contract. The new supplier had to stock a minimum inventory of critical items—pumps, bearings, belts—in a central warehouse before any plant cut over. Sarah also insisted on the new supplier providing on-site training at each plant during the first month. The result? Zero production downtime during the transition. That's rare. Luna: That's impressive. But what about the losers? The incumbents lost a big account. Did Sarah face any blowback? Lucas: A little. One incumbent's regional sales manager called her boss and complained that the process was unfair. But Sarah had documented everything—the pre-qualification criteria, the data sharing, the sealed-bid format. She could show that the process was transparent and fair. Her boss backed her. And honestly, the savings spoke for themselves. In procurement, if you save eight hundred thousand dollars and you can prove the process was clean, you're usually fine. Luna: Still, I've heard the argument that reverse auctions commoditise relationships, that they treat suppliers as interchangeable, and that they undermine long-term partnerships. What's your take? Lucas: I think that argument is valid for complex, engineered goods or strategic partnerships where innovation matters more than price. But for MRO, for office supplies, for raw commodities, reverse auctions are a perfectly legitimate tool. The key is to use them where the specification is clear and stable. If you're buying a specific valve with a known part number, and you've got five suppliers who can all deliver the same thing, then price is the differentiator. A reverse auction just makes the price-discovery process efficient. Luna: But Sarah didn't just use it for price discovery—she used the auction data to renegotiate service levels too, right? Lucas: Exactly. After the auction, she had a clear picture of the market-clearing price. So when she negotiated the contract with the winner, she could say, 'We know your cost structure, we know your margin, and we want to lock in these service levels: ninety-eight percent fill rate, two-day delivery to all plants, quarterly business reviews.' The supplier agreed because they knew the volume was real and the relationship was starting on a transparent footing. Luna: So it wasn't just about grinding suppliers down. It was about resetting the baseline. Lucas: Exactly. And that's the best use of a reverse auction: when the incumbent has become complacent and the market has shifted. It's a way to introduce competition and gather data that you can use to build a better relationship going forward—not to destroy the old one. Luna: I've got to say, stories like this make me think about the smaller procurement teams out there that don't have the bandwidth for a full reverse auction. Sarah had months to prepare. Is there a lighter-touch version? Lucas: Sure. You can run a mini reverse auction with just three suppliers over a few hours using online tools. Some procurement platforms let you do it for free for smaller spend buckets. The principle is the same—competitive tension, transparent rules, clear specs. You don't need to save eight hundred thousand dollars for it to be worth it. Saving ten thousand on a fifty-thousand-dollar category is still a win, especially if it only took you a day to set up. Luna: And if you're listening and thinking, 'I'd love to try this but I'm not sure where to start'—what's the first step? Lucas: Clean your data. Pick one category where you have a clear specification and at least three potential suppliers. Run a pilot. Don't announce it as a reverse auction to the suppliers—just say you're running a competitive bid. See what happens. The worst case is you learn something about your market. The best case is you save thirty percent. Luna: Sarah's story is a great example of procurement that's both data-driven and relationship-aware. I think we can all learn from how she handled the incumbents' pushback. Lucas: Definitely. And you know, if these conversations have moved your work forward in some small way—maybe you've tried a reverse auction, or you're thinking about cleaning up your spend data—a couple of dollars a month is genuinely what keeps these going. It's buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: Yeah, it's a small gesture but it really helps us keep the show ad-free and focused on practical stories like this one. Lucas: So, back to Sarah. One thing I didn't mention: after the transition, she ran a second round of competitive bids eighteen months later, just to keep the market honest. The incumbent from round one—the winner—actually lowered their price further because they had become more efficient. So the process didn't just reset the baseline; it created ongoing pressure to improve. Luna: That's the ideal outcome. A tool that drives continuous improvement rather than a one-time event. Lucas: Right. Reverse auctions get a bad rap when they're used as a blunt instrument. But when they're part of a broader category strategy—with data, with supplier development, with fair process—they can be a powerful lever. Sarah's story shows that procurement isn't just about cutting costs; it's about using the right tool for the right job. Luna: And knowing when not to use them. I imagine if she had tried this for a custom engineered part, it would have backfired. Lucas: Absolutely. If the specification is vague or the supplier relationship involves co-development, a reverse auction can destroy value. Sarah's success came from that discipline: she knew MRO was a commodity category with clear specs, so the tool fit. That's the real lesson—not the thirty percent savings, but the strategic thinking behind the choice of tool. Luna: Alright, I'm going to look at my own procurement processes with fresh eyes. Maybe there's a category I've been neglecting that could use a competitive reset. Lucas: That's the spirit. And if you do run a reverse auction, let us know how it goes. We'd love to share your story on a future episode.
