Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How a Buyer Used Tier 2 Audits to Uncover Hidden Risk
Transcript
- Lucas: So earlier this week I was talking to a procurement director at a mid-tier auto parts manufacturer — about $400 million in annual spend — and he told me something that stopped me cold. Luna: I'm listening. What did he say? Lucas: He said they'd been auditing their top 50 suppliers every year for a decade. Scorecards, site visits, financial health checks — the full program. But they had never once audited their suppliers' suppliers. Luna: Wait — never? Not even a financial check on the sub-tier? Lucas: Never. And he's not unusual. Most procurement teams, even sophisticated ones, stop at Tier 1. They assume their direct suppliers manage their own supply base. But here's the thing: that assumption can hide enormous risk. Luna: So what happened when they finally looked? Lucas: They ran a pilot on three of their top components. They mapped the full chain — not just their supplier, but the supplier's supplier. And in one case, they discovered that their Tier 2 — the company making a specialty alloy — was operating with safety certifications that had expired eighteen months earlier. The plant had one furnace that produced 80 percent of that alloy grade. Luna: One furnace. That's a single point of failure right there. Lucas: Exactly. If that furnace went down, the Tier 1 supplier would have been unable to deliver within six weeks. And our buyer's entire production line would have halted. The hidden cost of that risk was enormous. Luna: What did they do about it? Lucas: They launched a formal Tier 2 audit program. Three phases. First, mapping — they identified every critical component and traced it back to the raw material source. That took about four months for their top 20 components. Second, vetting — they audited the Tier 2 suppliers on safety, financial health, and capacity. Third, contingency planning — for each critical sub-supplier, they developed a backup plan. Luna: And the cost of all that? Lucas: The mapping phase cost about $80,000 in consultant time and internal labor. But here's the payoff: by uncovering that expiring certification, they avoided a potential shutdown that would have cost them roughly $3 million per week in lost revenue. They also negotiated a price reduction with the Tier 1 supplier because they now understood the actual cost structure better. Luna: So the Tier 1 supplier had been hiding margin in the sub-supplier relationship? Lucas: Not hiding, exactly — more like the Tier 1 supplier didn't have great visibility either. They were passing through the alloy cost without scrutiny. Once the buyer audited the Tier 2, they found that the alloy price was 12 percent above market because of inefficiencies at the sub-supplier. They helped the Tier 2 improve its process, reduced the cost, and shared the savings. Luna: That's a great example of what happens when you look one level deeper. Lucas: It is. And it's something more procurement teams should be doing. By the way, if you find these kinds of practical case studies useful — if this conversation has moved your work forward in some small way — I'll just say that a handful of listeners chip in monthly to keep the show ad-free and independent. It's buy me a coffee dot com slash fexingo. No pressure, just a sincere note. Luna: Yeah, it's a small group, but it makes a big difference. We appreciate every single one. Lucas: Alright, back to the audit. So the third phase — contingency planning — they created a playbook for each critical Tier 2 supplier. For that specialty alloy, they qualified a second sub-supplier in another region. That took six months and cost about $50,000 in qualification expenses. But now they have redundancy. Luna: And that's the kind of resilience that doesn't show up on a balance sheet until something goes wrong. Lucas: Right. The interesting thing is that the ROI on Tier 2 auditing isn't just about avoiding disasters. The buyer found that by understanding the deeper supply chain, they could identify cost reduction opportunities that the Tier 1 suppliers missed. Luna: Give me another example. Lucas: In a different component — an electronic sensor module — they traced the raw material to a specialty chemical supplier. That supplier was using an outdated catalyst that increased processing time by 30 percent. The buyer's team introduced a newer catalyst that cut the cycle time. The sub-supplier saved money, passed some of that savings to the Tier 1, and the Tier 1 passed it further up. Luna: So the buyer became a source of innovation for the entire chain. Lucas: Exactly. And that's a role procurement rarely plays. But it required the buyer to invest in technical expertise — they had an engineer on staff who understood chemical processes. Not every procurement team has that. Luna: What about smaller companies? Can a $50 million manufacturer do Tier 2 audits? Lucas: They can, but they need to be smart about scope. The auto parts buyer I mentioned started with just three components. That's manageable. The key is to focus on what's critical: components with long lead times, single-source sub-suppliers, or high value-add parts. Luna: So prioritize, don't boil the ocean. Lucas: Exactly. And if you don't have an internal engineer, you can partner with a third-party lab or a consulting firm that specializes in supply chain mapping. The cost is real but the downside of not knowing is often larger. Luna: What was the biggest pushback the buyer got from their Tier 1 suppliers? Lucas: Some resisted. They said, 'That's our supplier, not yours. You're overstepping.' The buyer handled it by framing the audit as a joint risk management exercise. They offered to share the findings and the cost savings. Most suppliers came around once they saw the potential upside. Luna: And the ones that didn't? Lucas: They were flagged as higher risk. The buyer started developing alternative Tier 1 sources. That sent a signal. Luna: Pretty clear signal. Lucas: Look, I think the broader lesson here is that procurement has a blind spot. We've gotten really good at managing direct suppliers — scorecards, contracts, audits. But the supply chain is deeper than most of us acknowledge. And the next big disruption might come from a supplier you've never even met. Luna: That's a good note to end on. Thanks, Lucas. Lucas: Thanks, Luna. See you next time.
