DTC brands overpay freight by 30-50% because carriers bill whichever is higher: actual weight or dimensional weight (length × width × height ÷ 139). A 2-lb product can bill as 7 lb. Audit your top SKUs, renegotiate with 3PLs, and document everything in an Operations Playbook so the fix survives beyond you.

Here's a number that made me sit up the first time I actually read it. Most DTC brands are paying 30 to 50% more in freight than their product should cost to ship. Not because a carrier changed the rates, not because fuel surcharges went up, but because of a formula almost nobody checks buried in a box size nobody's looked at since the day it got approved. Go grab it right now if you can. Get your best-selling SKU, the box It ships in, you're going to want the dimension in a second because I'm about to walk you through the exact math your carrier is running on you, and I bet real money you've never run yourself. I had not for years. I was so deep in negotiating rates and chasing down surcharges that it never occurred to me the box itself might be the problem. That's the thing about this one. It doesn't show up as a line item. It just quietly makes your freight bill look expensive every single month and they write off as the cost of doing business. Here's what's actually happening. Carriers don't bill you for what your product weighs. They bill you for whichever is bigger, the actual weight or something called dimensional weight, which is calculated off the size of your box. The formula is length times width times height divided by 139. Say your product weighs 2 pounds. It ships in a box that's 12 inches by 10 by 8, which honestly is a pretty normal size. A remarkable box. Nothing oversized about it to the eye. Run the math: 12 times 10 times 8 is 960. Divide that by 139 and you get under 7 pounds. A 2-pound product billed like it weighs almost 7. That's not a rounding error. That's more than 3 times the real weight on every single Until unit they ship every single month for as long as that box stays approved. And here's the part that gets me. It never once showed up as dim weight overcharge on your invoice. It just gets folded into a freight line that quietly creeps up, and you assume shipping costs more expensive. It didn't. Your box did the damage. The carrier just cashed the check. Now, here's what I'm not just telling you this as a shipping tip. This is an operations problem, not a freight problem, and it touches almost everything downstream of it. Think about where your landed cost per unit comes from. Freight is a real input into that number, and if your freight is quietly inflated by dim weight, your landed cost is wrong. Not a little wrong, wrong enough that the price you set, the margin you think you're protecting, and the contribution margin per order your whole team is making decisions against are all built On a number that was never real to begin with. And it cascades. Your marketing team is running ad spend against a margin target that assumes a freight cost that isn't the freight cost. Your finance side is forecasting cash based on unit economics that are quietly softer than they look. Your ops team might even be making inventory and reorder decisions off A landed cost that's inflated by a formula nobody explained to them. Because why would anyone explain dim weight to a demand planner? Nobody tells them to check. And this is why it's easy to miss for solo. It doesn't announce itself. It just sits underneath every other decision you make, from pricing to ad spend to whether An SKU is even worth carrying, quietly making all of them a little bit more. That's the actual cost, not the freight bill, the decision built on top of it. So here's what I'd actually do with this. Don't just check your best sellers and call it done. I made that mistake in the example I just walked you through, and I want to be straight with you about it. Your best seller is often not your worst offender. It's usually The SKU nobody touched in a year. The one that's been shipping in the same box since launch because nobody had a reason to refit it. That's carrying the worst dim weight gap in your whole catalog. Run this formula against your top 5 to 10 SKUs, not just the hero product. 5 minutes an SKU. That's it. Once you have the real numbers, you're not guessing anymore about which box to fix first, and you don't have to fix anything today to get value out of it. Maybe you've got inventory committed. Maybe your suppliers already tooled up for that box size and switching isn't a this-month decision. That's fine. Just knowing the real number changes how you price that SKU right now, and it changes the conversation the next time you're on the phone With your 3PL about rates. And that's really the whole point of what we've been building this month. This is fix number 3. The 3PL relationship test, the storage surcharge gap, and now this. 3 real things, 3 real dollar gaps, each one useful entirely on its own. But I want to be honest about the pattern I see with founders and the fixes like this. You learn it, you feel that little jolt of, oh, that's costing me money. You maybe even fix it, and then 6 months from now, you cannot remember what you negotiated or why, or whether your 3PL is even still honoring the storage terms you fought for. 3 good fixes sitting in 3 different places, none of it written down anywhere your team could actually pick up without you. So here's the ask: pull all 3 in one place. Not a folder of screenshots, not a Slack thread you'll never scroll back to. One simple document. Your 3PL's direct line and backup contact For peak weeks, your negotiated storage terms, the real cap, the notice period, the effective date, written down as an actual reference instead of half-remembered code. And now, your dim weight numbers on your top SKUs so packaging decisions get made against real math from here on instead of guesses someone made 3 years ago. So that's the build. Now wing? Actually means around here, not smarter fixes that are written down in one-takes that outlive the specific week you learned about them. 3 takeaways before I let you go. 1, your carrier bills you on the bigger of actual weight or dimensional weight, and most brands have never checked which one applies to their own boxes. 2, the worst offender in your catalog is Probably not your best seller. It's the SKU nobody's looked at. And 3, a fix you don't write down isn't a fix. It's a thing you remembered from one partner. If you want a starting point instead of building this from scratch, the Operations Playbook is linked below. It walks through all 3 pieces in a format you fill in with your own numbers today. That's September done. The next month, we shift again from the systems inside your 4 walls to something a lot of you thought you'd already solved by moving production out of one country and into another this past year to dodge a tariff. Spoiler: the country you moved to might not be nearly as safe as it looked. That's next month, starting Thursday. See you then.
