20 Painful and Expensive Operational Mistakes I See $100M Founders Make
All of them are entirely avoidable
After a decade running operations for DTC and apparel brands across the US, UK, and Europe, I have seen the same mistakes made at every level of scale. Some of them are small. Some of them are catastrophic. Most of them are quiet, compounding, and entirely avoidable.
This is not a list of theoretical risks. Every single one of these is something I have seen cost a real brand real money. Some of them I have seen cost brands seven figures in a single year.
If you are a founder or operator at a scaling DTC brand, read this carefully. There is a reasonable chance at least one of these is happening in your business right now.
1. If your supplier is communicating an issue, it is already too late to fix.
Suppliers do not flag problems early because early problems feel manageable and they do not want to create alarm. By the time they tell you, it is already urgent. The only way to know before it is too late is to build a reporting system that surfaces problems at the milestone level, not at the completion level. Weekly production updates, milestone sign-offs, and a clear escalation process are not bureaucracy. They are the early warning system that saves you from emergency air freight.
2. Air freight is not a logistics cost. It is the price of a broken process.
Every brand I have worked with that was spending heavily on air freight had the same root cause. A production delay that went undetected too long, a buffer stock policy that did not exist, or a sea freight window that got missed because nobody was watching the timeline closely enough. Air freight is almost always avoidable. When it is not avoidable it is usually because the decision was made six weeks earlier when it still could have been.
3. The brands losing the most money are not doing it dramatically.
They are losing $0.15 here, $0.70 there. Overpaid freight rates that were never renegotiated. Supplier terms set three years ago when volumes were a fraction of what they are now. Duty classifications that were set up incorrectly on day one and never reviewed. None of these feel urgent individually. All of them compound into something significant over time.
4. A 3PL can make or break your operation. Choose wisely.
Do not jump into bed with anyone without proper due diligence. Low quotes win the pitch and make the commercials look good on paper. The reality emerges six months in when the SLA failures start, the hidden fees appear, and the peak season capacity you assumed you had turns out to be committed to a bigger client. References, site visits, contract scrutiny, and a clear understanding of their capacity commitments are all non-negotiable before you sign.
5. Your cost of goods is almost never as low as it could be.
Most brands have never stress tested it. Most brands have never done a proper landed cost analysis. They know what they pay the factory. They have a rough idea of freight. But the full picture, including duties, 3PL inbound fees, quality inspection costs, packaging, and the amortised cost of samples and development, is rarely understood at the SKU level. Until you understand your true landed cost, you cannot make good decisions about pricing, margin, or supplier negotiation.
6. Founders often become the bottleneck they cannot grow past.
When a founder is managing supplier relationships, chasing production updates, dealing with 3PL issues, and firefighting operational problems, they are doing work that should be delegated. The operational work is not free just because the founder is doing it. It is being done at the opportunity cost of everything a founder should actually be focused on. Building the brand, developing new products, opening new markets. Hire ahead of the problem and delegate properly.
7. Dead stock is never a product issue.
It is a result of poor forecasting and improper buying processes. By the time stock is dead it has already failed twice. Once when it was bought in the wrong quantity and once when nobody intervened early enough to liquidate it before the storage cost compounded. Dead stock almost always traces back to a buying decision made without enough data, or a reorder trigger set without enough scrutiny. It is always avoidable. Fix the process before you blame the product.
8. Suppliers respect brands that have standards documented in writing.
Set the expectations early and hold them accountable. A verbal briefing is forgotten, misremembered, or reinterpreted the moment the factory floor gets busy. A written standard, a signed supplier agreement, a documented quality spec, these create accountability in a way that a phone call never can. If your quality expectations are not in writing, they are not really expectations. They are hopes.
9. Every time you accept a late delivery without consequence, you are training your supplier to be late again.
Suppliers are businesses. They manage capacity, they prioritise customers, and they respond to incentives. A brand that consistently accepts late delivery without raising it formally and without any consequence signals to the supplier that the delivery date is a preference rather than a commitment. This is entirely fixable. It requires a clear escalation process and the willingness to use it.
10. Stockouts are rarely caused by one thing.
They are usually a combination of failures across forecasting, design, buying, and logistics. The most common cause of a stockout is not a supplier problem or a demand spike in isolation. It is several small failures that compound. A forecast that was slightly off, a design that took longer than planned, a PO that was placed two weeks late, and a freight delay that removed the buffer. Understanding which combination caused the stockout is the only way to prevent the next one.
11. The brands that scale cleanly are not the ones that move fastest.
They are the ones that build the infrastructure before the volume demands it. The brands that hit $20M and break are almost always the ones that built the infrastructure for $5M and kept pushing. The supply chain that carries you to $10M will not automatically carry you to $30M. Building ahead of the curve is uncomfortable. Building behind it is expensive.
12. You cannot negotiate better supplier terms with a factory you do not understand.
The best supplier negotiations happen after a factory visit, not before one. When you understand a factory's capacity constraints, their cost structure, their other clients, and where they are making and losing margin on your orders, you negotiate from a position of knowledge rather than guesswork. Guesswork almost always leaves money on the table.
13. The cheapest price is rarely the best. But manage this with commercial awareness.
Open cost everything. Understand what something should cost before you accept what you are being quoted. The goal is not the lowest price. The goal is the right price for the right quality, delivered on time, with a supplier who has the capacity to grow with you. Chasing the lowest number at every turn is how you end up with quality failures, broken relationships, and air freight bills that wipe out every saving you thought you made.
14. The gap between what you think your landed cost is and what it actually is will surprise you almost every time.
I have done this exercise with enough brands to know that the number is almost always higher than the founder expects. Sometimes by 10%. Sometimes by 25%. The difference between what brands think they are paying to land a unit and what they are actually paying, once every cost is accounted for, is one of the most reliable places to find recoverable margin in any apparel business.
15. Chargebacks from wholesale retailers are a sign something upstream is not working.
Every major retailer has a vendor compliance guide. Miss your delivery window, get the labelling wrong, use the wrong carrier, or fail an EDI requirement and the chargeback is automatic. It comes off your next payment without warning. Chargebacks are not bad luck. They are the bill for a process failure that happened weeks earlier. Fix the upstream problem and the chargebacks stop.
16. Invest in software, team, and processes way before you think you need to.
The transition from informal to formal operational infrastructure is uncomfortable and time-consuming. It is also necessary and non-negotiable at scale. If your ops runs on WhatsApp and spreadsheets at $10M, you do not have a system. You have a group of people working very hard to compensate for the absence of one. This works until it does not, and when it stops working it usually stops all at once, during peak season, when the consequences are at their highest.
17. Inventory is not an asset until it moves.
Until then it is cash you cannot spend. Working capital tied up in slow-moving or non-moving stock is not sitting on the balance sheet doing nothing. It is actively costing you storage fees, it is occupying the cash that could be funding your next bestseller, and it is a problem that gets harder to solve the longer you wait. Inventory health is not a warehouse problem. It is a cash flow problem wearing a warehouse costume.
18. The best time to renegotiate supplier terms is when you do not need to. The worst time is when you do.
When you are in a crisis, when production is behind, when you need a favour, your negotiating position is at its weakest. When your relationship is strong, your volumes are growing, and you have options, your position is at its strongest. Most brands do the opposite. They leave terms unchanged when things are good and try to renegotiate when things are difficult. Get ahead of this.
19. Scaling internationally without understanding duties and HS codes will cost you more than the marketing budget that convinced you to expand.
International expansion looks clean on a revenue model. It looks messier when the first container gets held at customs, when the duty rate turns out to be double what was assumed, or when the HS code your supplier has been using for three years turns out to be incorrect and you are looking at a retrospective liability. Get this right before you ship, not after.
20. Every founder I have worked with who thought their supply chain was fine turned out to be wrong.
The ones who knew it was not were easier to help. The most dangerous position in operations is confident ignorance. Not knowing that you do not know. The brands that call me when things break are harder to help than the brands that call me before they do. An operational audit is not an admission that something is wrong. It is the fastest way to find out.
