How I Started in E-commerce at 17 — and What Losing My First Stores Taught Me
By Matan Guy · · 6 min read
I opened my first online store when I was 17. I didn't have a mentor, a business plan or savings to fall back on. I grew up in Netanya in a home that was, to put it gently, not easy, and what I did have was a strong feeling that I needed to build something of my own. eBay looked like the most accessible door: anyone could open an account, list an item and reach buyers far beyond Israel.
This is not a story about overnight success. It's a story about getting something wrong, losing it, and learning enough to start again on firmer ground. If you're young and thinking about selling online, I hope it saves you a few of the mistakes I made.
What starting actually looked like
In the beginning, I learned everything by doing. I read listings from other sellers, copied formats that seemed to work, and figured out shipping, photos and descriptions as I went. Every sale felt like proof that this was possible. Every question from a buyer taught me something about what people need before they hand over money to a stranger on the internet.
What I didn't do was read the rules carefully. I treated the platform's policies as background noise — something that applied to "big" sellers, not to a teenager with a handful of listings. That was the first and most expensive misunderstanding.
Then the stores got blocked
At some point my stores were restricted and then blocked. I won't pretend I understood every reason at the time. What I understood later was this: marketplaces don't owe any seller an account. They protect buyers first, because buyers are what keep the marketplace alive. When a seller's patterns — delivery times, item descriptions, account activity, buyer complaints, or simply not following the policies — look risky, the platform acts. It doesn't need to explain itself in detail, and it doesn't care how much effort you put in.
Losing those stores hurt. It wasn't only the lost work. It was the feeling that the ground had disappeared under me. For a while, I was angry at the platform. Eventually I realized anger was useless, because the platform wasn't going to change. I was the only variable I controlled.
Lesson 1: The rules are the business
The most important shift was understanding that the platform's policies are not an obstacle to your business — they are part of the business model you agreed to. When you sell on eBay, Etsy, Amazon or anywhere else, you're operating inside someone else's house. Their rules on item eligibility, shipping, returns, communication and intellectual property define what a sustainable business on that platform even looks like.
Today, before I touch a new platform, I read the seller policies end to end. Not skimming — reading. I keep notes on what is prohibited, what requires disclosure, what the expectations are around handling time and customer service. It's boring, and it's the single best risk-reduction step I know.
Lesson 2: Account health is an asset
When you're new, you think your assets are your products or your listings. In reality, one of your biggest assets is the account itself — its history, its reviews and its standing with the platform. Everything you do either builds or erodes that asset.
That means:
- Shipping on time, every time, even when it's inconvenient.
- Describing items honestly, including their limitations.
- Answering messages quickly and politely.
- Solving problems before they turn into disputes.
None of this is glamorous. All of it compounds.
Lesson 3: Don't build on a single point of failure
When my stores disappeared, I had nothing else. No email list, no social presence, no second channel. Everything depended on one account on one platform.
I'm not saying you shouldn't build on marketplaces — I still do, and I think they're one of the best ways to start. But over time you should build things you own alongside them: a reputation people recognize, content that shows how you think, relationships with customers and partners. This is a big part of why I later got so interested in personal branding.
Lesson 4: Rebuilding is a skill
The second time around, I moved slower and more deliberately. I studied before I acted. When I eventually moved to Etsy, I spent months learning how the marketplace works — how buyers search, how listings are presented, what Etsy's policies allow and require — before I tried to scale anything. That study became the foundation for my own way of working, which I call the ED method.
Rebuilding taught me that failure isn't the end of the story unless you stop there. It also taught me that the second attempt is only better if you actually change your approach. Repeating the same habits with more motivation just gets you to the same wall faster.
Lesson 5: Your circumstances explain you, they don't define you
I sometimes get messages from young people who come from difficult homes and feel like that rules them out. I understand the feeling. Coming from a hard place does make things harder — you have less safety net, less guidance and often less confidence.
But it can also give you something useful: a tolerance for discomfort and a reason to keep going. I wouldn't romanticize it. I'd just say that where you start is information, not a verdict.
If you're starting now
Here's what I'd tell my 17-year-old self:
- Read the seller policies of your platform before your first listing. Then read them again after your first month.
- Start small and boring. Learn shipping, customer service and listing quality before chasing volume.
- Protect your account like it's the business — because it is.
- Keep a simple log of what you tried and what happened. Your memory will lie to you later.
- Build one thing you own alongside the marketplace, even if it's just consistently sharing what you're learning.
- Expect setbacks. Plan for how you'd respond if something you rely on disappeared tomorrow.
I didn't get it right the first time. Losing my first stores was the most useful thing that happened to me early on, because it forced me to learn how online commerce actually works — not how I hoped it worked. If you're in that place right now, rebuild slower, read more, and keep going.
