Your Sourcing Is Killing Your Margins (Here’s How Real Operators Fix It)

Founder/operator Lara Guevara (Moon Supply Chain) argues that sourcing mistakes—not marketing—are often the root cause of vanishing margins for DTC/ATC brands. She outlines a structured sourcing system: build a vendor universe and backups; evaluate and score vendors by capability and performance (not "vibes"); standardize RFQs and BOMs to surface hidden costs; design quality into production with audits, clear specs, and inline inspections; and negotiate strategically across price, terms, design simplification, tariffs and volume to align incentives. The video concludes with a CTA to Moon Supply Chain’s sourcing system and a private Running DTC community.

Let me start with something uncomfortable but true. Most ATC brands don't lose money in marketing. They lose money before the product even ships at the factory. In the code, in the vendor decision, in the this seems fine moment that no one questions. And the worst part, most founders don't even realize it's happening. They think my ads stopped working, my margins are just tight. This vendor is just hard to deal with. But what's actually happening is this. Your sourcing decisions are quietly bleeding your business. And today I want to walk you through how sourcing actually works when it's done right. What most brands get wrong and how to think about vendors, pricing, quality and negotiations like a real operator, not someone guessing their way through. Alibaba if you're a DTC founder, this will change how you look at your supply supply chain. And if you're a supply chain professional, this will sharpen how you add value inside a brand. Let's go into it. Most people think sourcing is just find the factory, get a quote, place the po. That's not sourcing, that's shopping. Real sourcing is strategy. Because every sourcing decision affects your margin, your cash flow, your lead times, your quality, your ability to scale, and your stress level. As a founder, I've seen brands scale revenue and still go backwards financially because they picked the wrong vendor or they accepted the wrong moq, or they didn't understand what was actually included in the quote. They also had no leverage, no backup, no data. And once you're in production, it's already too late. That's why sourcing isn't a one time task, it's a system. Let's talk about vendor research. Most founders do one of three things. One, use the first factory that replies. Number two, use a referral without vetting. Or number three, stick with one vendor forever because switching feels scary. All three are risky. Smart brands build a vendor universe. And that means mapping vendors by product type, knowing who's good at what, and understanding capacity, materials and risks. You also have backups before you need them because the moment you rely on one factory for everything, you lose leverage. Good sourcing starts with screening fast, eliminating bad fits early, knowing what red flags to avoid, and understanding which vendors are worth pursuing long term. This alone can save brands tens of thousands per year. Now here's a tough one. A lot of brands choose vendors based on they reply fast or they seem nice or they said yes to everything. That's not a capability assessment, that's vibes. And real vendor evaluation looks at manufacturing capabilities, quality systems, lead time, reliability, Communication under pressure, pricing behavior over time, past performance signals. Because the factory that says yes to everything is often the one that misses timelines or they cut corners, they changes the materials without you knowing it or surprises you. Mid production data beats feelings always. When you score vendors properly, decisions get easier and and conversations get more professional. Now let's talk about RFQs or requests for quotes and costing. This is where most margins quietly disappear. Founders often don't realize quotes can hide costs. BOMs can be inflated, materials can be swapped later without you knowing it. Freight assumptions can be wrong. Labor complexity adds up fast and and if you don't structure your RFQs properly, you cannot compare factories fairly. You're not comparing apples to apples, you're comparing guesses. Now Strong brands standardize RFQs, understand the BOM structures or bill of materials. They spot inflated unit cost, then catch material switches early and know their target margin before sampling. If you don't do this upfront, you end up fixing margin problems after launch and by then you are already stuck. Here's another misconception. Quality is not something you check at the end. Quality is something you design into the process. That means pre production audits, clear specs, inline inspections, final inspections, clear defects, communication, the acceptance criteria everyone understands. Factories don't fail because they are not good or bad people. They fail because expectations weren't documented. The factory will only be as good as your documentation. Brands that treat QC as a system, reduce refunds, protect their brands, avoid emergency fixes and sleep better at night. Last piece Negotiation Good negotiation isn't aggressive, it's strategic. It's not just about unit price, it's about volume. Leverage your raw materials, alternatives, design simplification, payment terms, production planning, origin decisions. That affects tariffs and the best vendor relationships are built on aligned incentives. When vendor understand your growth plan as a company, your standards, your expectations, your long term volume. You stop fighting every PO and start building partnerships. If any part of this made you think, oh, we're definitely leaving money on the table. You're not alone.
