Your Biggest Seller Might Be Your Biggest Problem

Lara Guevara shows DTC founders how to audit products using contribution margin analysis, which includes COGS, freight, fulfillment, returns, and acquisition costs. Products under 5% CM get killed, 5-15% get fixed through a five-lever playbook, and over 20% get scaled. Real examples include Maya's loss-making flagship and Carlos's COGS renegotiation.

Every product in your catalog is doing one of three things right now: it's making you money, it's bleeding you dry, or it's sitting in purgatory eating cash while you hope it figures itself out. In the next 20 minutes, I'm going to walk you through the exact audit I run when I step into a DTC brand and figure out which products to kill, to fix, and to pour gas on. This isn't Fury, This is the same systems that save brands hundreds of thousands of dollars and starts with 5 supply chain bottlenecks that tells you everything. Now let me tell you about Maya. Maya had a product she kept alive for 18 months that was losing $4 on every single sale. It was her first SKU, the product she built the brand around, still had loyal customers. Still sold 200 units a month, consistent, but when we did the full contribution margin audit, it was at 3%. When you allocated overhead, she was losing money every time someone clicked buy. Now, if you watched my first video in this series, the contribution margin playbook, you already know the difference between gross margin and contribution margin. Maya's gross margin looked healthy. Her contribution margin told the real story. So if you haven't watched the Contribution Margin Playbook, I'll link it in the description and at the end of this video. That's the foundation for everything we're doing today. The day she finally discontinued it, nothing happened. A few customers' emails. Within 60 days, nobody remembered, but her overall profit margin improved immediately. So here's the thing. Maya's not unusual. Almost every brand I audit has product like this, and the reason they survive isn't because the data isn't there. It's because the founder never looked at the data through the right lens. So today I'm giving you that lens: 5 bottlenecks. Each one tells you something specific about whether a product is a kill, a fix, or a scale. Now let's go. Here's what most founders call margin: revenue minus cost of goods, and that's it. And that number is a lie because real contribution margin includes everything that touches the product on the way to the customer: COGS, inbound freight, outbound shipping, pick and pack, returns, payment processing, and customer acquisition costs. When you add all that up, the product you thought was at 50% margin might actually be at 12%. I did an entire deep dive on this in my last video, The Real Cost of the Product. In that one, I walk through 4 real founder stories where the gap between what they thought their product cost and what it actually cost was 30 to 50%. If your jaw isn't on the floor after watching that one, check your numbers again. And here's the framework that makes the decision objective. Under 5% contribution margin with no realistic path to improvement, that's a kill. Between 5% and 15% with clear levers you can pull, that's a fix. Over 20%, that's a scale. Pour gas on it. Notice the end conditions. They matter. A 3% product isn't automatically a kill if you have a clear path to fix it, and a 10% product isn't automatically a fix if you've already tried everything. The criteria force you to be honest about reality, not hopeful about possibilities. Do this now. Pull your full contribution margin for every SKU, not gross margin, full CM with freight, fulfillment, returns, and tax. Sort them into the 3 buckets. If you need help building this report, go watch video 1 first. I give you the exact spreadsheet structure. The second bottleneck that reveals whether a product lives or dies— you don't actually know how fast it sells. Most founders track weekly sales, monthly sales, Shopify snapshots, but velocity lives at the daily level. And velocity is the heartbeat of your inventory decisions. Inventory planning equals velocity times lead time. If you don't know how fast you're selling, you don't know when you'll run out. And when you don't know when you'll run out, you do the thing that kills more products than bad reviews. You overbuy. You panic order huge batches. You lock up cash in 6 months of inventory because it feels safe, and now your fixed product that was a 12% margin is drowning in warehousing costs that drag it below 5%. Remember the home decor brand from my last video? They ordered 8,000 units on a trend. The trend picked before inventory arrived, and just storing that product cost them $30,500 beyond the original investment. That's what broken velocity data does. It turns your warehouse into a cash crematorium. Every SKU has its own behavior, and it needs its own treatment. Your hero SKU, steady, predictable, this is your scale candidate, tight replenishment loop, safety stock, never let it go out. Your seasonal SKUs, plan it like a campaign with a start and end date. Your spiky SKUs driven by ads or influencers don't forecast the same as steady sellers. Your new SKU is unknown, small initial batches, earn the right to a bigger order. When you forecast all SKUs the same way, you break your cash flow. You subsidize your losers with your winners. So do this now. Pull daily velocity for your top 10 SKUs over the last 8 weeks. Classify each one by behavior type. I bet at least 2 are getting the completely wrong inventory treatment. If you only have one factory, you don't have a supply chain, you have a risk. Your supplier raises prices 8% because they know you have nowhere else to go. Your lead time jumps from 30 to 50 days because they prioritize a bigger client. A QC batch fails and you can't reroute production. This is one of the biggest differences between 7-figure and 8-figure brands. The ones who scale have vendor depth. The ones who plateau have vendor dependency. And here's where this connects to kill, fix, and scale. When a product lands in the fix bucket, The very first lever is COGS renegotiation. Let me give you a real example. Carlos had a kitchen product stock at 8% CM. He didn't want to kill it, but he couldn't keep it at 8%. Week 1, went back to his supplier with a volume commitment, 40% more over the next year for better pricing. Got 12% lower unit cost. CM moved from 8% to 11%. Then he attacked returns, 14% rate because product images didn't show true size. He added comparison images, returns dropped to 9% by day 60. CM hit 13%. Fulfillment, boxes 2 sizes too large, dimensional weight is killing him. Custom box saved 80 cents per order, CM hit 15%. Price test, $2 more for a new customer. Conversions barely moved. CM hit 17%. By day 90, 8% to 19%, from kill candidate to a product he could feel good about. And if you're thinking, wait, how do I even know what my real fulfillment costs are? That's exactly what video 2 solves. I walk through Jennifer's story where her 3PL quote said $2.50 per order, but the real cost was $5.95. You need those real numbers before you can pull any of these levers. 5 levers for every fixed product in order of impact. 1, COGS reduction, usually the biggest. 2, reduce returns, fix the root cause. 3, optimize fulfillment, audit line by line. 4, adjust pricing. Scariest but often most powerful. 5, cut acquisition cost. Stop advertising it, let it sell organically, or bundle it. Work them systematically. Give yourself 90 days. If you can't get above 15% CM by then, it's a kill. No extensions. Here's a bottleneck nobody talks about that quietly determines whether your scale products usually scale. Your inbound pipeline. If your supplier says 30 days, it's never 30 days. Real lead time includes production, QC, packing, booking, vessel transit, customs, dryage, receiving, and put away. In video 2, I told you about Marcus who thought his freight was $0.8 per unit, but real number was $2.96. When you add origin charges, destination charges, customs broker duties, and tracking, if your lead time math is using fantasy freight numbers, your entire replenishment schedule is a friction. And receiving delays inside your 3PL, those can cost you 3 to 7 extra days and thousands in lost revenue. I've watched brands miss launch windows because the product sat at the dock and nobody at the warehouse was ready for it. This matters for kill-fix scale because hidden lead time costs change your verdicts. Your scale products that stocks out because you miscalculated lead time by 2 weeks, that stockout killed your momentum. Your ads stopped working because there's nothing to sell. Your fixed product whose margin keeps getting eaten by emergency air freight— the product isn't the problem, the timing is. Safety stock is not extra. It's protection from supplier delays, ad spikes, QC failures, and port congestion. Safety stock is cheaper than air freight, cheaper than refunds, and cheaper than stockouts. And freight itself, Most founders book reactively. High-growth brands plan proactively. Routes, timelines, carrier capacity, consolidation, cost modeling. Freight is a margin event, not an admin task. So do this now. Map the through end-to-end lead time for your top 3 products, not the supplier code, the real number from PO to live in warehouse. The last bottleneck ties everything together. You don't have a system for reviewing your portfolio. Most brands audit their products once when something breaks, then they react. Brands that grow profitably have a rhythm. Weekly, they have velocity review plus stock check. Monthly is PO planning and CM refresh. Are your fixed products improving or declining? Quarterly, full SKU review. Kill, fix, scale, sort on the entire catalog. And yearly, supplier negotiation season. In video 1, I showed you exactly how to build a CM by SKU report and told you to update it monthly. This is where the report lives inside your business. It's not a one-time exercise, it's the monthly heartbeat of your kill, fix, scale rhythm. And here's the rebalancing piece. Every brand has slow SKUs, dead SKUs, old packaging, duplicate variants. That's trapped cash. Rebalancing unlocks $20,000 to $150,000 through bundling, liquidating, marketing, and redistributing. Our clients unlock that just from this exercise alone. Your warehouse can kill your cash flow faster than a bad supplier if you're not auditing it. Receiving time, put away speed, pick accuracy, packing standards, shipping SLAs, error rates. A tight warehouse equals higher margin. So do this now. Set a recurring calendar event. Every Monday, velocity check. First of the month, CM refresh. End of quarter, full kill-fix-scale audit. Don't skip it. Now, before I give you the action plan, I need to address the biggest blocker. Every founder I work with has that product, the one they know isn't working but can't kill. And the reason is almost always the same. We already invested so much. The tooling cost, example, $40K. The initial inventory was $25K. 2 years of development time. That's a long investment, but the money's gone. Whether you sell another unit or never sell one again, the $40K doesn't come back. The only question that matters going forward is, is each new sale profitable? If no, you're adding new losses to old ones. $40K becomes $50K, then $60K each month. You delay, the damage grows. If I were starting fresh today, no history, no emotional attachment, would I launch this product? If the answer is no, it's a kill. Daniel had a product doing $180K a year in revenue, third bestseller by volume. CM after audit, 2%. We stopped advertising, raised the price 15%, cleared inventory with a while supplies last campaign, reallocated everything to his scale products. Revenue dropped 8% the quarter after the kill. Profit went up 22%. The kill isn't losing, it's pruning so the healthy parts of your business can grow. Now, if you're watching this thinking, I need to do this for real, but I want someone walking me through the full system, that's what MOVE Accelerator program is. It's 11 modules that connect marketing, finance, and supply chain into one growth system, sourcing, inventory planning, logistics, cash flow, quality, the complete DTC supply chain built as one operating system. Links in the description. But let me give you the action plan first because you can start this today, right now, without anything else. Everything we covered in videos 1, 2, 3, that's modules 5 through 8 of the accelerator. If you want the full 11-module system with templates dashboards and certification, it's there. Here's what to do this week. Step 1: Sort your products. Pull your full contribution margin data the way I showed you in video 1. Sort every SKU into kill, fix, or scale using the criteria from today. Under 5% with no path forward, kill. 5 to 15% with levers, fix. Over 20%, scale. Step 2: For your kills, act immediately. Stop advertising today, raise prices 10-15%, clear inventory in 60-90 days. You don't need an announcement, currently unavailable works fine. Step 3, for your fixes, make a 90-day plan. Pick your first lever: COGS, returns, fulfillment, pricing, acquisition cost, in that order. Set milestone for day 30, 60, 90. If you don't hit 15% by day 90, it becomes a kill, no extensions. Step 4: For your scales, protect the winner. Check inventory positions before increasing ad spend. Make sure you can handle 2x demand. Scale marketing 20 to 30% per month. Negotiate better volume pricing and don't mess with the formula. And step 5: Set the rhythm. Weekly velocity review, monthly CM refresh, quarterly full kill fixed scale audit, yearly supplier negotiation. I've built a complete kill-fix scale decision toolkit that walks you through everything we cover today: sorting worksheet, 5-lever fix template, 90-day roadmap, discontinuation checklist, scale prep checklist, and first link in the description. If you watch all 3 videos this month, the contribution margin playbook, the real cost of the product, and today's kill-fix scale audit, you now have a complete unit economics system. You know how to calculate real margins, find hidden costs, and make portfolio decisions based on data and not feelings. If you want to turn that into a full operating system with sourcing, logistics, cash flow, quality, the whole DTC supply chain connected, that's what the accelerator does. Links in the description. Here's what I want you to remember: Making no decision is a decision. It's a decision to keep losing money on products that aren't working while starving products that are. Go sort your products, make the hard calls. Your business will thank you. Stop hoping and start deciding. I'll see you in the next one.
