Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How One Buyer Used Supplier Co-Location to Slash Lead Times
Transcript
- Lucas: So today I want to talk about a strategy that sounds almost too simple — but when it works, it changes the entire rhythm of your supply chain. Supplier co-location. Luna: You mean physically moving a supplier's people or operations into your own facility? Lucas: Exactly. Not just a desk at your office — full-on embedding their production team, sometimes even their inventory, right next to your assembly line. The case I have in mind is a mid-sized electronics manufacturer in the Midwest — let's call them VoltCore. They make power management modules for industrial equipment. Luna: And what was the pain point that pushed them to try co-location? Lucas: Lead times. Their main supplier of custom capacitors was based in Taiwan. Standard shipping was six to eight weeks. And when demand spiked, they'd get hit with another two to three weeks of delays. VoltCore's production planners were constantly firefighting. They couldn't commit to customer delivery dates. Luna: So bringing the supplier closer — literally — could compress that timeline. Lucas: Right. But they didn't just ask the supplier to open a local warehouse. They proposed a full co-location: the supplier would lease a dedicated production line inside VoltCore's own factory. They'd staff it with a dozen engineers and operators, using their own equipment, their own quality processes. Luna: That's a big ask. What was the supplier's incentive to say yes? Lucas: VoltCore guaranteed a five-year purchase commitment at a fixed volume — enough to cover the supplier's capital outlay within eighteen months. Plus, the supplier got free rent and utilities inside VoltCore's facility. Their only real cost was the equipment and labor. So from their perspective, it was a low-risk way to lock in a major customer. Luna: And VoltCore got what — lead time down to what? Lucas: From eight weeks to about three days. Because the capacitors were now being made essentially just-in-time, a hundred feet from where they were assembled. They went from ocean freight to a hand truck. But the benefits went beyond speed. Luna: Such as? Lucas: Quality feedback loops. When a batch had a defect, the supplier's engineers could walk over to the assembly line, see the problem firsthand, and adjust the process within hours. Before, a defect would mean a four-week cycle of shipping samples back and forth. They claimed a 70 percent reduction in defect rates in the first year. Luna: That's a huge improvement. But I imagine there were real downsides too — like intellectual property exposure. Lucas: That was the biggest risk. VoltCore's engineers were working alongside the supplier's team, so proprietary designs could leak. They mitigated it with a co-location agreement that included separate secure zones, badge-only access, and a strict prohibition on the supplier's staff viewing certain production areas. And they added a clause that any IP developed jointly during the co-location would be owned by VoltCore. Luna: Did the supplier push back on that? Lucas: They did. But VoltCore's position was that the supplier was already being compensated through the guaranteed volume and free facilities. The final compromise was that the supplier retained IP for any process improvements that were purely internal to their capacitor production, while VoltCore got anything that directly affected the design of the power modules. Luna: That sounds like a net win for VoltCore. But what about the supplier's other customers — did they worry about capacity being tied up? Lucas: That was actually one of the clever parts of the deal. VoltCore agreed that the supplier could use up to 20 percent of the co-located line's capacity for other customers, as long as it didn't disrupt VoltCore's orders. That gave the supplier flexibility and reduced their dependency on a single buyer. Luna: So it wasn't a total lock-in. It was more like a strategic partnership with clear boundaries. Lucas: Exactly. And the financial results were striking. VoltCore's total cost of acquisition for those capacitors dropped by about 15 percent, even after accounting for the free rent they gave the supplier. Because inventory carrying costs plummeted — they went from holding twelve weeks of safety stock to just one week. Luna: Stock that they had to finance, warehouse, and insure. Lucas: Right. So the savings were real. But co-location isn't for every situation. This worked because the component was high-value, had a long lead time, and was critical to VoltCore's product. For a commodity like fasteners or packaging, it probably wouldn't justify the overhead. Luna: Let's talk about the pitfalls. What are the failure modes that listeners should watch out for? Lucas: First, cultural friction. VoltCore's workers had a different pace than the supplier's team. There were tensions over shift schedules and break times. They had to set up a joint steering committee that met weekly for the first six months to iron out those issues. Second, communication breakdowns — because now you're dealing with different org charts, different management styles. Luna: So co-location doesn't eliminate the need for relationship management. It actually intensifies it. Lucas: Completely. And third — exit complexity. If the arrangement ends, you have to repatriate equipment, renegotiate supply agreements, and potentially rebuild inventory buffers. VoltCore built a sunset clause that gave each side six months' notice and a detailed transition plan. They never used it, but it was there. Luna: I'm curious about the numbers on the implementation timeline. How long from the initial conversation to capacitors rolling off the line inside VoltCore's factory? Lucas: About seven months. Three months of negotiation — mainly on the IP terms — then four months for the supplier to procure and install the equipment. VoltCore also had to modify their facility to add a separate entrance and secure storage. That cost them about $200,000, which they recouped in inventory savings within a year. Luna: So a relatively modest upfront investment for a dramatic operational improvement. Lucas: And it opened up other opportunities. Once the co-location was running smoothly, VoltCore started using the supplier's engineers to help design their next-generation product. They had a built-in R&D partner who understood their constraints intimately. Luna: That's a classic example of moving from a transactional relationship to a collaborative one. Lucas: It really is. And it's a model that more companies are considering, especially as supply chain resilience becomes a board-level priority. But the key is to structure the agreement so both sides win — not just the buyer dictating terms. Luna: Before we wrap, I want to say — if you've been getting value from these conversations, whether it's a new idea you've applied or just a better way to think about a problem, you can support the show at buy me a coffee dot com slash fexingo. It's a small way to keep this ad-free and focused on what matters. Lucas: Yeah, exactly. Every bit helps us keep digging into real cases like this. And we genuinely appreciate the listeners who chip in. Luna: So back to co-location — do you see this becoming more common, or is it still niche? Lucas: I think it will grow, but slowly. It requires a level of trust and operational maturity that many procurement teams haven't built yet. But for high-criticality components, it's a tool that can deliver outsized returns. My advice to listeners is to start with a small pilot — maybe just one supplier, one component — and measure everything: lead time, quality, cost, and relationship health. Luna: And go in with clear legal boundaries and an exit plan. Lucas: Non-negotiable. Thanks, Luna. And thanks to our listeners for spending time with us. Next episode we'll look at a case where co-location went wrong — a cautionary tale. Luna: Looking forward to it.
