Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How One Buyer Cut Costs by Rethinking Supplier Lead Times
Transcript
- Lucas: So, Luna, I've been digging into something that I think a lot of buyers just accept as a fixed fact of life: supplier lead times. You know, the supplier says six weeks, you plan around six weeks, done. Luna: I mean, that's how it usually goes. You can negotiate price, payment terms, even quality specs, but lead time feels like a number they hand you and you just have to live with it. Lucas: Right. But there's this one buyer at a mid-size manufacturer in Ohio who decided to challenge that assumption. They were a precision components maker, and they had a chronic problem: every time they needed a rush order, they were paying expedite fees that ate into their margins. Luna: Expedite fees are the worst. It's like paying extra for the privilege of getting what you needed yesterday. Lucas: Exactly. So this buyer, let's call her Sarah, she had a supplier that consistently quoted a six-week lead time on a critical machined part. Sarah's team was constantly expediting, and the cost was adding up. So she decided to ask a simple question: why six weeks? Luna: And what did the supplier say? 'Because that's how long it takes'? Lucas: Pretty much. But Sarah pushed them to break it down. She asked for a detailed timeline: how long for raw material, how long in the queue, how long on the machine, how long for inspection, how long in transit. And what she found was that the actual production time was only about three and a half weeks. The other two and a half weeks were buffer. Luna: Buffer? That seems like a lot. Was it just padding to protect themselves? Lucas: Partially. Suppliers add buffer to handle variability—machine breakdowns, material delays, their own customer demands. It's a safety margin. But Sarah realized that this buffer was costing her money. She was paying for inventory holding costs on parts she didn't need yet, and when things got tight, she was paying expedite fees on top of that. Luna: So she was essentially paying twice—once for the buffer and once to bypass it. Lucas: Exactly. And she saw an opportunity. She went back to the supplier and said, 'Look, we understand you need buffer, but can we work together to reduce it?' And she didn't just demand a shorter lead time—she proposed a pilot. Take one part number, commit to ordering in larger, more predictable batches, and in exchange, the supplier would agree to a four-week lead time instead of six. Luna: And the supplier went for it? That's a big ask. Lucas: They agreed, but only for that one part and only for three months. The results were pretty telling. Sarah's team saw a 12 percent reduction in inventory holding costs on that part, and they didn't have to pay a single expedite fee for it. The supplier, in turn, found that the more predictable ordering helped their own scheduling, so they weren't actually losing anything. Luna: It's a win-win if you frame it right. But I'm curious—how did Sarah get the supplier to share that level of detail? Most suppliers would be pretty defensive about their internal timelines. Lucas: That's the key. She didn't come in asking for a concession. She came in asking for transparency. She framed it as, 'We want to understand your process better so we can be a better customer.' And she shared her own data too—her demand forecasts, her inventory levels. It was a collaborative conversation, not a demand. Luna: So it's about building trust and showing that you're willing to give something to get something. Lucas: Right. And that's the core of what I want to talk about today: how to actually approach lead time reduction without blowing up the relationship. It starts with understanding that lead time is not a monolith. It's made up of several components—raw material procurement, queue time, actual processing, inspection, and shipping. Each one can have its own buffer. Luna: And the buyer's job is to figure out which parts are real and which are just padding. Lucas: Exactly. Sarah's story is a perfect case study. But before we dive deeper, I have to say—if this conversation is giving you some ideas for your own procurement work, that's what we're here for. And the reason we can keep doing this, ad-free, is because of listeners who support us. If today was genuinely useful, you can help keep the lights on at buy me a coffee dot com slash fexingo. That's buy me a coffee dot com slash fexingo. Luna: Yeah, it really does make a difference. Even a small contribution helps us keep the conversations going. Lucas: So, back to the lead time puzzle. Once Sarah had that breakdown, she realized that the buffer wasn't just one big chunk—it was spread across different stages. There was raw material buffer, queue buffer, and even inspection buffer. Each one had a different cause and a different fix. Luna: Can you give an example of how you'd tackle each one? Lucas: Sure. Raw material buffer is often about supply uncertainty. If the supplier's own raw material supplier has long, unpredictable lead times, they'll add extra days. In Sarah's case, the raw material for that part was a specialized alloy, and the supplier was keeping a safety stock of it. But Sarah realized that if she committed to a longer-term forecast, the supplier could order the alloy in larger quantities and reduce their own lead time. Luna: So you're sharing your forecast to help them plan better. Lucas: Yes. And for the queue buffer, that's about how long a part sits waiting for the next machine. That can be reduced by better scheduling, but it often requires the supplier to prioritize your orders. Again, that's something you can negotiate if you're a valuable customer. Luna: And inspection buffer? That's the one that usually surprises me. I think of inspection as a fixed step. Lucas: It is fixed, but the buffer is about how much time is built in before inspection actually happens. Maybe the parts sit in a bin for a day before someone gets to them. If you can agree on qualified parts that have a documented inspection history, the supplier might be willing to reduce that buffer for you. Luna: So it's about peeling back each layer and seeing where the slack actually is. Lucas: Exactly. And that's what Sarah did. She and the supplier went through each component and identified where they could trim without risking quality or reliability. The result was a 33 percent reduction in lead time—from six weeks down to four—without any premium cost. And the savings on inventory holding and expedite fees added up to a significant amount over the year. Luna: But I have to ask—is there a cautionary tale here? I remember a story about a buyer who pushed too hard on lead time and ended up with quality issues because the supplier cut corners. Lucas: Oh, absolutely. That's the flip side. If you just demand a shorter lead time without understanding the process, the supplier might rush through production, skip inspection steps, or use lower-quality raw material to speed things up. The key is that Sarah's approach was collaborative and data-driven. She didn't just say 'give me four weeks'—she worked with the supplier to find a way to make four weeks feasible. Luna: So it's not about squeezing them; it's about redesigning the process together. Lucas: Right. And there's a framework I like to use when thinking about this. It's three steps: first, ask for a lead time breakdown. Second, identify where the buffer is and why it's there. And third, propose a pilot that tests a reduced lead time with clear metrics on quality and on-time delivery. Luna: And the pilot is crucial, right? Because it de-risks the change for both sides. Lucas: Exactly. You're not asking for a permanent commitment. You're saying, 'Let's try this for one part, for a few months, and see if it works.' If it does, you can expand. If it doesn't, you've learned something without a major disruption. Luna: And what about the supplier's perspective? Do you think they're generally open to this kind of conversation, or is it an uphill battle? Lucas: It depends. Some suppliers are receptive because they see the value in a more efficient relationship. Others are more resistant because they've been burned before by buyers who just want to push risk back on them. That's why trust and transparency are so important. You have to show that you're willing to share data and make commitments that make their life easier too. Luna: So it's a partnership, not a transaction. Lucas: Exactly. And going back to Sarah's case, the supplier actually told her that her willingness to share forecasts and commit to larger orders was what made them comfortable reducing the buffer. They felt like they were working with someone who understood their business, not just someone trying to squeeze them. Luna: That's a great takeaway. I think a lot of buyers underestimate the power of just asking the right questions. Lucas: Totally. And I'd add that it's not just about asking—it's about being willing to listen. When Sarah first got the breakdown, she could have just said 'cut the buffer,' but instead she asked 'why is that buffer there?' And that opened up a whole conversation about their production constraints and how she could help. Luna: So, what's the one thing a listener could do tomorrow if they want to try this? Lucas: Pick one part from a supplier where you've been expediting regularly, and ask for a detailed lead time breakdown. Just ask. You don't have to negotiate anything yet. Just get the information. You might be surprised at what you find. Luna: And then you can come back to us and tell us how it went. Lucas: We'd love to hear that. In the meantime, I'm curious to see if more buyers start treating lead time as a negotiable variable. I think it's an underused lever. Luna: Agreed. It's not just about the cost of the part; it's the cost of waiting for it.
