Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How One Buyer Used Multi-Sourcing to Break a Monopoly
Transcript
- Lucas: There's a rule in procurement that sounds obvious but gets broken all the time: never let a supplier become the only game in town. And yet, single-sourcing happens for all kinds of understandable reasons — technical complexity, long qualification cycles, relationships that go back a decade. But when that supplier knows they're the only game, the balance of power shifts entirely. Luna: And usually, you don't realize how much power they have until they decide to use it. Lucas: Exactly. Today's episode is about a buyer who learned that the hard way. A mid-sized manufacturer in the Midwest — we'll call them Apex Manufacturing — made a single precision-machined part that went into their flagship product. They sourced that component from one supplier, a family-owned shop they'd worked with for over twelve years. Luna: Twelve years is a long relationship. At that point, it's almost like a partnership. Lucas: It was. The relationship was built on trust, handshake agreements, and pricing that stayed relatively stable. But then the supplier's founder retired, his son took over, and within six months, Apex got a notice: a 40 percent price increase, effective in 90 days. The son had brought in a consultant who'd benchmarked their pricing against industry averages and decided they'd been leaving money on the table. Luna: Ouch. And Apex had no second source qualified, so they couldn't just walk away. Lucas: Correct. The buyer — her name is Rachel, she's the VP of Supply Chain — told me she spent three sleepless nights running scenarios. Pay the 40 percent and eat into margins, or try to pass the cost to customers and risk losing business. Neither option was good. But then she realized something: the supplier didn't know she didn't have a backup. They assumed she had options. So she decided to create one. Luna: She went out and found a second source, even though the part was technically complex. Lucas: She did. But it wasn't fast. The part had tight tolerances — plus or minus five microns on certain dimensions — and it was made from a specialty alloy that few shops could machine. Rachel started by asking her engineering team what the real technical requirements were. They gave her a list of ten critical parameters. Then she went to trade databases and reached out to her network in the precision-machining association. Luna: Was she upfront about why she was looking? Or did she keep it quiet? Lucas: She kept it quiet. She framed it as a routine capacity backup review. She didn't want word getting back to her current supplier. Eventually, she identified three shops that had the equipment and the alloy experience. She sent them a request for quote, but more importantly, she sent them a sample part and asked them to machine a prototype to spec. Luna: So she's running a qualification process in parallel with the 90-day clock ticking. Lucas: Yes. Of those three, one came back with a prototype that passed dimensional inspection but failed a stress test. Another quoted a price that was actually higher than the incumbent, even after the 40 percent hike. Only one shop — a mid-sized operation in Ohio — passed the technical audit and quoted a price that was 18 percent below what the incumbent was now charging. Luna: Still took time, though. How long from start to qualified supplier? Lucas: About eight weeks. So she had maybe four weeks left before the price increase kicked in. At that point, she called the incumbent for a meeting. She brought the Ohio supplier's quote, the test results, and a timeline for transition. She didn't threaten. She just said, 'We've qualified a second source. We'd prefer to keep working with you, but we need pricing that reflects the market.' Luna: And the incumbent's reaction? Lucas: The son was surprised. He asked to see the test data. Rachel shared it — the Ohio shop's quality report was actually slightly better on one dimension. The incumbent came back a week later with a new offer: a 22 percent reduction from their proposed price, plus a three-year volume commitment lock. Rachel accepted, but with a clause allowing her to source up to 30 percent from the second supplier at her discretion. Luna: So she ended up with a dual-source arrangement, not just a price cut. Lucas: Exactly. She got a net 22 percent cost reduction compared to the original 40 percent increase, but more importantly, she eliminated the concentration risk. The Ohio supplier is now a qualified backup, and she runs about 70-30 split between the two. She told me the incumbent's quality actually improved too, once they knew there was competition. Luna: I can imagine. Nothing focuses a supplier's attention like knowing the buyer has another option. Lucas: Right. And Rachel said something that stuck with me: 'I didn't want to be in a relationship where I couldn't leave.' That's the core insight. Even if you never switch, the ability to switch changes the dynamic completely. Luna: But let's talk about the cost of qualifying that second source. It's not free — the prototypes, the testing, the management time. For a smaller company, that can be a real barrier. Lucas: It's a valid point. Rachel estimated the qualification cost at about $15,000, including the prototypes and three engineering days. But against the 40 percent increase — which would have cost them roughly $120,000 annually — it paid for itself in under two months. Luna: Yeah, that math works. But what about cases where the qualification cost is much higher? Like aerospace or medical devices, where you're looking at hundreds of thousands in validation. Lucas: That's a different ballgame. In those industries, single-sourcing is often a strategic choice because the switching cost is so high. But even there, I've seen buyers use a 'paper qualification' — auditing a supplier's processes and certifying them as technically capable without actually running production. That way, if the incumbent pushes too hard, you can accelerate the real qualification. Luna: So it's about having a credible threat, not necessarily a fully ramped alternative. Lucas: Exactly. Rachel's approach is replicable even for complex parts: identify the critical specs, find one or two alternate suppliers who can technically meet them, get a prototype or a process audit, and then use that as leverage. You don't need to have the second source producing at volume. You just need to have done the work to show it's possible. Luna: And if I'm a buyer listening, the first step is to look at your single-source items and rank them by risk. That's probably the hardest part — actually knowing which parts are truly single-source versus just historically sole-sourced. Lucas: Right. There's a difference between 'sole source' — where only one supplier can make it because of a patent or unique capability — and 'single source' — where you've chosen to use one supplier but others exist. Rachel's case was single-source, but she'd been treating it like sole-source. The distinction matters. Luna: If these conversations have moved your work forward in some small way, we've got a simple way to keep them coming. It's buy me a coffee dot com slash fexingo. No subscription, no ad-free tier — the show stays free for everyone. Just a small gesture if today's episode was worth a coffee to you. Lucas: Yeah, and it genuinely helps. We don't run sponsors, so listener support is what keeps the lights on. No pressure, but if you found value, that's the link. Luna: Back to the case. So Rachel now has two suppliers running, quality is up, cost is down. But what about the human side? That twelve-year relationship must have changed. Lucas: It did. The incumbent's son initially felt betrayed, but over time, Rachel says the relationship actually improved. They have more structured business reviews now, and the son respects that she's a professional buyer, not just a friendly customer. The relationship became more transactional, but also more transparent. Luna: So sometimes you have to risk a relationship to save it. Lucas: In a way, yes. Rachel's advice to other buyers: 'Don't wait for a crisis to start qualifying. The best time to find a second source is when you don't need one.' She now requires her team to maintain at least a paper qualification for every single-source part that represents more than 5 percent of spend. Luna: That sounds like a smart policy. And it's not just about price — it's about resilience. If that Ohio shop hadn't been qualified, and the incumbent had a fire or a flood, Apex would have been in real trouble. Lucas: Exactly. The price hike was the trigger, but the real value was risk mitigation. Rachel told me that within a year, the Ohio supplier actually came up with a design improvement that reduced scrap by 8 percent. That never would have happened if they were just a theoretical backup. Luna: So multi-sourcing doesn't just give you leverage — it can also bring in new ideas. Lucas: Right. And that's the upside that often gets overlooked. Rachel's story is a good reminder that the cost of qualifying a second source is an investment, not an expense. For her, the return was a 22 percent price correction, improved quality, and a supply chain that can absorb a shock. Luna: I think the takeaway is clear: if you have a single-source supplier, especially one you've been with for years, it's worth spending a few weeks to figure out what the alternatives actually are. Even if you never switch, you'll negotiate better. Lucas: Absolutely. Next time you're in a quarterly review with your key supplier, imagine having a second-source quote in your back pocket. You don't have to use it. But knowing you can? That changes everything.
