Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How a Buyer Used Supplier Diversity to Cut Costs 21 Percent
Transcript
- Lucas: So there's this assumption that's been floating around procurement circles for years — that supplier diversity costs more. That if you go with a minority-owned or woman-owned business, you're paying a premium for the social good. Luna: Right, and I've definitely heard that from category managers who push back on diversity targets. They say their job is to get the lowest price, full stop. Lucas: Exactly. But a case out of a New Jersey-based auto parts manufacturer — let's call them Jersey Auto Components — turned that assumption on its head. Over 18 months, they shifted about 12 percent of their direct material spend to certified diverse suppliers, and their overall procurement costs dropped 21 percent. Luna: Twenty-one percent? That's not just a rounding error. How did they get there? Lucas: It came down to three things. First, they didn't just set a diversity target and hope. They restructured their RFP process to include diverse suppliers in competitive bids alongside incumbents. Second, they used total cost of ownership — not unit price — as the decision metric. And third, the diverse suppliers they brought in typically had leaner cost structures: lower overhead, fewer layers of management, more flexible labor arrangements. Luna: Meaning the diverse suppliers were actually hungrier and more efficient? Lucas: In many cases, yes. A lot of these suppliers were smaller, privately held, and they couldn't afford fat margins. They priced aggressively to win. The buyer's procurement team ran a parallel sourcing event — they invited three incumbents and five new diverse suppliers to bid on a basket of 30 part numbers. The diverse suppliers came in 18 percent lower on average, and after factoring in logistics and quality, the total cost was still 14 percent lower. Luna: So the savings were real from day one. But I imagine there was internal resistance — the category managers who'd been working with the incumbents for years. Lucas: Oh, absolutely. The procurement director told me the biggest pushback came from the purchasing managers who had relationships with the old suppliers. They argued that switching mid-contract would hurt reliability. So the company did something smart — they phased the transition. They didn't cut anyone overnight. They let the diverse suppliers earn a small share first, maybe 5 percent of a category, and ramp up based on performance. Luna: That's the classic 'try before you scale' approach. Did any of the diverse suppliers stumble? Lucas: A couple did on delivery timing early on. But because the buyer had structured the contracts with shorter lead times and penalty clauses, those issues were resolved fast. Within six months, the three main diverse suppliers were hitting 98 percent on-time delivery, matching the incumbents. Luna: What about certifications? Did they require official MBE or WBE status? Lucas: Yes. They required third-party certification — from the National Minority Supplier Development Council or the Women's Business Enterprise National Council. That gave them auditable spend data, which mattered when they reported to corporate and to customers who were asking about diversity spend. Luna: And the 21 percent savings — was that purely from lower pricing, or did other factors play in? Lucas: Pricing was the biggest piece — about 14 of the 21 points. The rest came from reduced inventory. Because the diverse suppliers were more flexible, they could do smaller, more frequent deliveries. The buyer cut its safety stock by about 30 percent in the categories where diverse suppliers were primary. Luna: That's a working capital benefit on top of the direct savings. So the total value proposition is stronger than the headline number suggests. Lucas: Exactly. The treasury team calculated that the inventory reduction freed up about $2.4 million in cash. That's real money — especially for a mid-sized manufacturer where every dollar of working capital counts. Luna: I also wonder about the timing. They started this in early 2025, right when tariffs were being adjusted on imported auto parts. Did that affect the math? Lucas: It did, and it actually strengthened the case. Many of the diverse suppliers were domestic, so they weren't exposed to the same tariff volatility as the offshore incumbents. The buyer told me that during the tariff uncertainty, the diverse suppliers' pricing stayed stable, while some of the offshore suppliers had to add surcharges. That made the total cost gap even wider. Luna: So supplier diversity became a resilience play as much as a cost play. Lucas: Exactly. And that's a lesson a lot of procurement teams are starting to grasp. The old assumption that diversity costs more is rooted in a narrow view of cost — unit price in isolation. When you look at total cost of ownership, including inventory, logistics, and risk, the equation flips. Luna: I know a lot of procurement pros listen to this show, and they might be thinking, 'That's great for auto parts, but my category is different.' What would you say to them? Lucas: I'd say the principle transfers. Whether you're buying IT services, packaging, or logistics, the key is to create a competitive field where diverse suppliers can actually bid. Too many companies just set a diversity goal and then hand-pick a few suppliers without a real sourcing event. That's when you end up paying more. Luna: You need the process, not just the target. Lucas: Right. And you need to train your category managers on total cost of ownership. The buyer we studied did a two-day workshop with each category team, walking them through how to build a TCO model that includes quality, delivery, and risk costs. That was the turning point. Luna: So the method matters more than the mandate. Lucas: Exactly. And honestly, this is the kind of work that makes procurement really satisfying. You're not just cutting costs — you're opening up the supply base to new players, building resilience, and creating economic opportunity. And the numbers followed. Luna: Quick honest thing — a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds making this many of these episodes. If these conversations have moved your work forward in some small way, that's how it stays ad-free. Lucas: Yeah, it's a small group that keeps it going, and we're grateful. And it keeps the show independent. Luna: So back to the case — one thing I found striking is that after the initial 18-month program, the buyer expanded it to more categories. They're now targeting 25 percent diverse spend by 2028. Lucas: And they're on track. The procurement director told me that the hardest part was the first six months — building the pipeline, getting the RFPs right, and overcoming the internal skepticism. Once the savings showed up on the P&L, the resistance melted away. Luna: It's a good reminder that data beats dogma every time. Lucas: Every time. If you're a buyer sitting on the fence about supplier diversity, run a pilot. Take 5 percent of spend in one category, run a competitive bid with diverse suppliers, and measure total cost. The results might surprise you.
