#215 Why Your Margins Are Shrinking (Even When Sales Are Up)
26 Dec 2025 · 17 min
Neil explains why e-commerce sellers watch margins shrink even as sales climb. TikTok Shop raised European commissions from 5% to 9%, new shipping rules tightened, and the EU's adding a €3 duty on low-value parcels in 2026. He walks through how to track contribution margin, stress-test fee changes, and diversify channels before platforms squeeze harder.

When a platform grows fast, who do you think actually pays for the growth? Because growth is never free, it's just subsidized at the beginning. And if you're feeling margin pressure lately, higher fees, tighter rules, more compliance, more friction around fulfillment, it's not a coincidence. It's not you suddenly doing something wrong, it's the platform maturing and those subsidies are going away. Guess who's eating the difference? So today we're talking about the hidden cost of platform growth, how the fees, logistic rules, compliance requirements quietly shift as the platforms scale, and how sellers who don't understand that shift end up losing margin without realizing why. So we're diving into what's happening right now on TikTok Shop and a recent EU policy change and what's going on there and what you need to understand. Once you see the pattern, you can play around with it. And that's the difference between what reading the— what the platform changes and operating with the intent behind the platform changes. Guys, welcome to episode 215 of the High Voltage Business Builders Friday Week in Review. It's the day after Christmas. I'm Neil. Hopefully you guys have got your comfy pants on. If you're like me, you probably tried to control it, but you might've had a little too many goodies yesterday. And if you're new here, welcome. If you're a returning listener, welcome back to the only e-commerce breakdown that helps you think like an operator and act not like just a seller, but a business builder. All right, let's get into it. To understand what's going on right now, you have to look at the platforms and how they behave once they reach scale. So every major e-commerce platform goes through some of the same cycles. Amazon did it years ago. And Shopify has been doing it gradually because it's a different beast and TikTok is clearly moving through it right now. So in an early platform's life, everything is optimized for growth. Sellers are incentivized to join, fees stay low, rules are usually flexible, logistics options are wide open, and enforcement is light because friction slows adoption, right? So that phase usually builds in volume. And as a platform needs inventory, sellers, and buyer feedback to lock it in, buyers will show up consistently. Sellers will depend on the traffic. The economics really start the change in the platform. Now we're seeing that shift happen in real time right now. So over the last few weeks, TikTok has announced a higher seller fee in several European markets, moving commissions up from where they were originally with their business models. So if you've been paying attention to that, you know, good for you. If you haven't, keep, keep paying attention. At the same time, TikTok has begun tightening logistics requirements in certain regions, limiting what shipping methods you can use and pushing more volume toward approved or higher cost fulfillment options. Separately, the EU has confirmed new duties on low-value e-commerce parcels that will go into effect in 2026. This change directly impacts cross-border sellers running high-volume, low-AOV models, especially those relying on duty thresholds that existed for years. None of these moves are random and none of them are isolated. They're all examples of platforms and regulators shifting from growth mode optimization, okay, into operational costs. And once scale exists, The priority stops beyond expansion and starts becoming control, standardization, and margin protection. So where sellers can get caught like you is assuming the conditions they entered into originally will stay the same as the platform changes. So pricing models are built on those early fee structures, right? Fulfillment workflows are designed around flexible shipping rules. Volume of scale without stress testing is what happens when costs move even slightly. On your margins, but platforms and these changes can show up and actually cause a big hit. They show up in layers. And there's a few points of commission here to pay attention to. Shipping restrictions being there, compliance requirements that add additional cost per unit. Of course, we know about the big word, tariffs. Revenue might hold steady or even grow while margins quietly compress underneath the weight of that. That's why many sellers feel the pressure without even being able to point to a single cause. Cash flow tightens, profitability can slip. And it feels suddenly to you, even though the signals have been there the whole time. So what's happening right now with TikTok Shop and the EU policy changes isn't an anomaly. It's a bit, you know, platform maturity at the end of the day. And once you understand that, the fees that increase and the tighter rules stop feeling so surprising. They just become expected. So just be aware of that, right? And when something is expected, you plan around it. That's the difference between reacting to platform changes after margins disappear and operating with enough foresight to protect it. Probably why you're listening to this podcast, huh? So what does it mean for you? When people hear fee increase, they usually think isolation. A few percentage points doesn't sound catastrophic, but when platforms apply enough pressure to that one lever, it could affect several things at once. So start with the fees. TikTok Shop increasing their seller commission in parts of Europe from roughly 5% or so to as high as 9% doesn't just shave profit. It changes your pricing and your math. If you were running a product with a healthy contribution margin at around 5% commission or so, that same product can slide close to break even at 9% once ads, fulfillment, and returns are factored in. This is always why we say pay attention to your greenlight process and to know your numbers, because most sellers don't reprice immediately. They absorb it first, and that's where margin quietly disappears. Now we layer in logistics, and when a platform tightens shipping rules, and restricts which carriers you can use, your cost per order often rises if your commission rate stays the same. Now, sellers who are using lower-cost postal routes or regional carriers will suddenly get pushed into approved logistics networks or premium shipping options. The difference might be a few dollars per order, but on a product with thin margins, that's often the difference between profit and loss. And unlike ad costs, fulfillment costs are harder to optimize once options are removed. So what should you do? Make sure you know your numbers. If you had any questions about that, go over to caimandata.com, grab maybe our $5 GPT, or grab some of the free training and community access and find out what do my costs actually need to be? Does it actually green light? So guys, then there's compliance, and that's one of the things that's being changed right now. The EU's decision to impose a flat €3 duty on low-volume e-commerce parcels starting in 2026 is a good example of how regulation compounds product and platform pressure. For sellers running high volume, low average order volume, or AOV models, that €3 change isn't a rounding error. It's a structural cost increase that scales with order count, not revenue. Now, if you're selling at a €15 or €30 product, that duty alone can wipe out a meaningful portion of your margin. And it doesn't replace existing costs. It stacks on top of platform fees, fulfillment, payment processing, and returns. And this is how sellers get trapped. Now revenue still looks fine and orders still come in. Dashboards don't necessarily flash red lights and each order contributes basically to less cash than it used to. And over time, working capital will tighten. Cash flow, timing, those things get worse. Inventory turns become a little bit more riskier. So guys, whether this is an EU update or a US-based seller update for TikTok, just keep in mind, I'm crossing this over because this is impacting the EU right now, which means clearly it's coming. To the U.S. And as we know, TikTok just transitioned its seller platform to a new ownership, which means this is going to change here very soon. So most of you aren't going to notice that they forced you to do this. You're going to pay attention to it maybe reactionary or after the fact. There'll be a fee increase. It'll be manageable. Logistics will change and it will sort of be manageable and compliance costs will own its own manageable situation. But if you stack those all together, they're going to reshape the business, maybe yours too. And that's what we're trying to avoid, right? So as platforms understand this, they really push all the pressure through one obvious change. They spread it out so adoption stays high and resistance will stay low. That's why operators like you guys don't just track revenue growth. You track contribution— contributing margin after platform costs. The model where scenario fees rise, shipping costs increase, and compliance adds friction is something that you should be aware of as you run your numbers and run your business by the numbers. Because the risk isn't losing sales overnight. The risk is running a business that looks healthy on the surface while margins drain underneath. And you will usually find it at tax time or later in the year when you're doing your accounting and going, where the heck did all my profit go? And by the way, that's a bad time to do it. So why do most sellers miss this? And most importantly, how do you make sure that from today on you do not? So usually pay attention to the shiny object syndrome and the wrong things. Most of you do. Most sellers watch revenue, order count, sessions, and ROAS, and as long as those numbers look healthy, everything seems fine and the business appears to be growing. That's the trap. Platform risk does not show up on revenue first. It shows up on margin quality. Fees can increase, shipping can get more expensive, and compliance will add that friction we mentioned earlier for top-line numbers. And those may stay flat or even improve, and in some cases, higher volume hides the issue. And as more orders look greater and stronger as the business is churning, They may actually be contributing less profit than ever before. It's important. It's a trap, guys. And this rarely feels very obvious at first, especially when you're excited about the growth because activity gets high and then the cash flow accumulation slows. Inventory may end up sitting longer. Obviously, profits will stop compounding, and then you as a seller will feel the pressure without being able to pinpoint to a single cause. It's another reason sellers miss how performance-based changes induce change to your business from the platform. So costs are rarely raised all at once. Again, they're pressure applied gradually. Gradually, to slow the churn rate, the commission increases, the logistical rules, the regulatory updates—they probably don't take effect until next year, so I'll pass the buck. But each change looks small enough; you shouldn't be ignoring it as they compound together and can reshape the economics of your business. Now again, platform dependency makes this harder to see. When a platform becomes a primary source of demand, sellers stop evaluating it objectively; they optimize inside the system instead of stepping back. To assess whether or not the system still works. Your pricing gets adjusted, your costs get absorbed, and your volume gets pushed to compensate. And that's how margin erosion goes unnoticed. So to make sure you don't miss this, you have to change what you measure. The operators should still track revenue and ROAS, return on your advertising spend, but they should prioritize contribution margin after platform cost. They should care about how much cash each order produces once the fees, fulfillment, returns, and compliance are accounted for. They should watch how that number changes over time, especially after policy updates. They should also stress test the business against small changes. If a 2-point fee increase or a shipping cost adjustment can materially change profitability, that's not noise, that's exposure. So don't be exposed. The goal, of course, is making a platform risk visible early while there's still time for you to adjust and respond. So once you have understood how and why the platform costs shift, the question becomes, how do you evaluate, you know, evaluate your exposure before it turns into a problem? Operators don't just try to guess the next policy update. They assume the platform will continue in tightening economics over time. The work is to figure out how sensitive your business is to those changes. The first thing operators look for is fee sensitivity, not whether a product is profitable today, but how fragile that profitability will be in 90 days. If 2 or 3 point increase in commission is meaningful and changes contribution margin, that product is exposed. And if the business only works under one fee structure, It's dependent on a condition won't last. Now, if you're a single product business, you must get into a multi-product business, a portfolio, what we call a 5x5 product methodology. Okay. When you do that, you lower your risk and increase your volume. You increase the numbers game, which is very important that one of these products may be impacted. But of course, as an overall portfolio, not all of them necessarily will be impacted in the same way. The next control you have is fulfillment. So you must look at how flexible you are. In the shipping and logistics. If a platform restricts a carrier, pushes volume into approved fulfillment networks, or changes delivery requirements, those costs can be managed without breaking economics. Can they be managed? Right? And if the answer is no, fulfillment isn't a lever, it's a constraint for you. So you're gonna need to figure that out, right? So if there's regulatory exposure, okay, operators map where their volume comes from and where it goes. They look at which markets rely on favorable thresholds, exemptions, cross-border efficiencies. If a single policy change adds a fixed cost per order, they want to know that before it shows up in the P&L. Okay, P&L, right? Profit and loss statement. So channel concentration is the next check. If one platform controls the majority or demand of your product fulfillment fees and payment timing, that may not be diversification. That could be concentrated risk. So operators should not avoid different platforms because of this, but they don't pretend risk and should not pretend risk doesn't exist. Which is why you should not stay platform dependent in 2026. You should multichannel, omnichannel platforms. Okay. Finally, operators look at the margins over time, not a snapshot. They track contribution margin after platform costs on a rolling basis, which is why we talk about a cash flow plan, which usually is 90 days. Okay. You watch how it moves after fee changes, logistics updates, and compliance shifts. And if margin is slowly declining while revenue stays flat or grows, that's a signal worth acting on early. There's no difference between reaching the platform and changes and planning for them. At the end of the day, you just need to make sure that it is not painful before you adjust. In simple terms, operators look for fragility where there's still room to move. That's how platform risk stays manageable instead of terminal. All right, so here's what you should do now. Platform growth is attractive, brings volume fast, brings demand, can even simplify demand, and it always comes with these trade-offs: the fees, the tightening rules, the control shifts that potentially move you away from being the controller of your business. So pressure test your business against these changes. Don't assume current conditions will ever hold. In other words, don't take your hands off the wheel of your business. Look at your contribution margin, other platform costs, and ask yourself, how does it hold up if fees move? Look at your fulfillment setup and ask if flexibility is really in the shipping rules if they were to change for you. And look whether your volume continues to come from and how it's exposed to any regulatory or compliance shifts. If your business only works on today's rules, that is a risk worth addressing while margins still give you room to move. The goal isn't to predict every platform change or decision, even regulatory. It's to stop being surprised by them. Sellers will typically react when costs go up on their P&L. Operators plan for cost pressure before it gets there. That's a difference that matters more as we head into 2026. All right guys, that's a lot to unpack.
