Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How a Buyer Used Quality Audits to Cut Returns by Half
Transcript
- Lucas: So you buy a batch of components, they pass incoming inspection, your manufacturing floor is happy, product ships, and then three weeks later customer returns start climbing. That's the exact scenario a mid-sized electronics manufacturer found themselves in last year. Luna: Returns were running around 7.2 percent of shipments, and the CFO was not happy. Lucas: Right. The procurement team had been focused on cost per unit and delivery reliability. But the return rate was eating into margin. So they decided to try something they hadn't done systematically before: a process-based quality audit of their top five component suppliers. Luna: And this isn't a compliance audit, right? They weren't checking for ISO certifications. Lucas: Exactly. A compliance audit is paperwork — you confirm the supplier has a documented quality system. A process audit is boots on the floor. You watch actual operators at actual workstations. You look at tooling, gauges, work instructions, how material is handled between stations. The buyer sent two engineers and one procurement lead to each supplier for two full days. Lucas: The results were striking. They identified forty-two discrete failure points across the five suppliers. But here's the thing — thirty-one of those were in packaging, labeling, or final handling, not in the core manufacturing process. Luna: So most of the defects weren't about component quality at all. They were about how the parts were packed and shipped. Lucas: Exactly. One supplier was using a corrugated box that flexed during transit, causing fine-pitch connectors to bend. Another was overpacking anti-static bags, which trapped moisture. The buyer's engineers documented every single finding with photos and measurements. Lucas: They then created a corrective action plan with specific deadlines — thirty days for packaging changes, sixty days for process documentation updates. Each supplier had to submit evidence of the fix: photos of the new workstation layout, signed-off work instructions, training logs. Luna: And they tied the corrective actions to the supplier scorecard, right? I remember reading that they made completion of corrective actions a weighted factor in quarterly reviews. Lucas: Yes. They gave it fifteen percent weight in the overall score. Suppliers who missed deadlines saw their score drop, which affected their allocation of future business. That created real accountability. Luna: At the same time, these conversations — the ones where you say 'we found these issues and here's what we need' — they can be tense. How did the buyer keep the relationship constructive? Lucas: It's a great question. The buyer framed the audit as a joint problem-solving exercise, not a punitive inspection. They said, 'We want to reduce returns together, because returns hurt both of us — we lose customer trust, you face potential chargebacks.' Most suppliers actually appreciated the detailed feedback. Several said no other customer had ever sent engineers to look that closely at their process. Luna: One supplier even implemented the packaging changes across their entire customer base, not just for this buyer. So the audit had spillover benefits. Lucas: Right. And within nine months of completing the corrective actions, the buyer's return rate dropped from 7.2 percent to 3.8 percent — a forty-eight percent reduction. The cost savings from fewer returns, fewer warranty claims, and less customer service time easily paid for the audit team's time many times over. Luna: That's a concrete win. And I love that it wasn't about squeezing suppliers on price. It was about process discipline. Lucas: Yeah, that's a theme we keep coming back to on this show — the biggest gains in procurement are often not about the price you negotiate, but about the information you gather. And if these kinds of insights have helped you in your own work, I'll mention that we keep the show free of ads by design.

Appreciate anyone who does. Lucas: So back to the process audit. One of the most interesting findings from that buyer was about the difference in defect rates between first and second shift at one supplier. The night shift had a defect rate nearly double the day shift. Luna: What caused that? Was it lighting, supervision, fatigue? Lucas: All of the above. The engineers observed that night shift operators had less access to the quality engineer — there was only one quality engineer covering both shifts, and they worked days. So night shift problems got documented but not resolved in real time. The buyer recommended that the supplier stagger quality engineering coverage. That single change reduced the night shift defect rate by about thirty percent. Luna: That's a low-cost fix. No capital investment, just a schedule change. Lucas: Exactly. And that's typical of what process audits uncover. You find what I call 'organizational friction' — small gaps in communication, training, or tooling that add up to real quality problems. The buyer documented fifteen such friction points across the five suppliers. Lucas: Another example: at one supplier, the work instructions for a critical soldering step were in English, but the operators on the line primarily spoke Vietnamese. So they were relying on tribal knowledge passed down from senior operators, which varied from person to person. The buyer required translated work instructions with photographs. Defect rate on that line dropped by forty percent within two months. Luna: That's a massive improvement from something so simple. And it shows that the buyer wasn't just auditing for compliance — they were auditing for effectiveness. Lucas: Right. And they created a simple audit report template that they now use as a standard part of supplier onboarding for any new high-risk component. It includes a checklist of about thirty process questions, plus a section for photographic evidence. They've since conducted similar audits on eight additional suppliers. Luna: So the initial five-supplier pilot turned into a permanent capability. What's the one piece of advice you'd give to a procurement team that wants to start doing process audits but doesn't know where to begin? Lucas: Start with your highest-return product line. Look at which components or finished goods have the highest return rate or the highest warranty cost. Pick the top three suppliers for that product line and plan a two-day on-site audit for each. Bring one engineer who knows the product and one procurement person who knows the supplier relationship. And go in with a spirit of curiosity, not accusation. You're there to learn, not to punish. Luna: And be prepared for surprises — like finding out that your biggest quality problem came from a packaging box, not a circuit board. Lucas: Exactly. In procurement, the root cause is rarely where you expect it. That willingness to look under the hood is what separates a good procurement function from a great one.
