If you’re just starting out or looking to scale your online business, learning from someone who has been through the highs and lows can save you years of trial and error. After spending 15 years building eCommerce businesses from the ground up, there is one core lesson I wish I had known earlier:
Never build your business on someone else’s platform.
That means avoiding dependence on third-party marketplaces like Amazon when launching your brand. Let me explain why.
The Biggest eCommerce Mistake I Made in the Beginning
Like most new sellers, I thought the smartest way to make money online was to start on Amazon. The platform had trust, traffic, and infrastructure already in place. It seemed like a no-brainer.
But I quickly discovered that selling on Amazon does not mean owning a business. You are renting space in someone else’s ecosystem. You are not in control of the customer relationship, the data, or even the rules. All of that belongs to Amazon.
Your customer is Amazon’s customer. You never see their email, cannot remarket to them directly, and have limited ways to build loyalty. You are left chasing one-time sales without the ability to grow long-term value.
While money might appear to be coming in, you have to look deeper. Margins are often low because of fierce competition. You are not just competing on product. You are competing on price, delivery time, and advertising spend. That does not include the hidden costs that creep in quietly. Sellers often absorb the cost of returns, which can be significant. Amazon forces sellers to accept returns, and in most cases, the seller loses the cost of shipping to the customer. In some cases, you may also lose the return shipping if the item is not restocked or is damaged. Add in customer fraud, inventory errors, or operational mistakes, and the margins can quickly vanish.
On top of that, Amazon’s fees constantly increase. There are referral fees, fulfillment fees, storage fees, advertising costs, and additional charges. With every new expense, your profit margin gets smaller. Your revenue may look good on the surface, but your net income tells a different story.
The most dangerous part is that the rules can change at any time. One policy update, algorithm shift, or account suspension can wipe out your income in hours. Even if it is a mistake, getting reinstated is not guaranteed. You could be left without access to your own products, sales history, or customer reviews.
A real business is built on assets you control. Amazon is not that. It is a distribution tool, not a foundation.
Why Retail Arbitrage Is a Risky Trap for New Sellers
You have probably seen the videos. Someone walks into a Nike outlet, scans shoes, lists them on Amazon, and claims they made hundreds of dollars before even leaving the parking lot. This model is known as Retail Arbitrage, and it is often pushed as an easy way to start making money with no experience.
But here is the truth. Retail Arbitrage is not a sustainable or smart long-term business strategy.
What these so-called “gurus” fail to tell you is that selling branded products like Nike without being an authorized reseller can lead to intellectual property (IP) complaints. These complaints can result in your listings being removed, your account being suspended, or even a permanent ban from Amazon.
It goes beyond platform rules. Large brands like Nike and Apple have full legal teams working every day to shut down unauthorized sellers. They send cease-and-desist letters. They file formal complaints. Some even pursue legal action. If you sell these products without proper authorization, you are taking a serious risk.
I have seen countless posts on Amazon’s own seller forums from people who got suspended and now regret following advice from content creators who pretended to be experts. Their defense is always the same: “I saw someone do it online.” But Amazon does not care. And neither will a brand’s legal team.
Many of these “gurus” are not experts. They are marketers selling you the dream. They do not fully understand Amazon’s policies or intellectual property law. Following their advice may cost you your account, your money, and your future opportunities.
If you are serious about building a business, avoid Retail Arbitrage. It may seem like a shortcut, but it teaches you nothing about owning your brand, serving customers, or building something that lasts.
What I Would Do If I Were Starting Over
If I had to start from scratch today, here is what I would do instead.
1. Build a Real Brand
A brand gives you pricing power, customer loyalty, and long-term recognition. It lets you stand out in a crowded market and build something people remember and recommend.
2. Launch Your Own Website First
A direct-to-consumer website gives you full control over your profit, customer relationship, and marketing. It allows you to collect emails, build repeat buyers, and test new offers without restrictions.
3. Use Amazon as a Channel, Not the Core
Amazon can be a helpful traffic channel once your brand is established. But do not rely on it entirely. Use it as a tool to grow awareness and then convert those customers into long-term relationships through your own site.
4. Focus on Profit, Not Just Sales
Revenue without profit is just noise. When you own your platform, you control your costs and can create higher-margin offers. Profit is what lets you reinvest, hire help, and grow.
5. Ignore Trends and Get Rich Quick Tactics
Every year brings new trends that promise quick wins. Most fade out fast. What lasts is great products, strong messaging, and consistent execution. Build wisely, not reactively.
