You have a gem in your hands (literally). A collection of handcrafted pieces with a powerful story, a polished aesthetic, a competitive price… and you’re ready to sell online.
But you come to the big question: “Should I set up my online store or start selling on a marketplace like Zalando, Amazon, or ECI?”
Many entrepreneurs, whether in jewelry, fashion, beauty, food, or home decor, are stuck right there: between the freedom of their own eCommerce business and the immediate reach of a marketplace.
BE CAREFUL!! There’s no single right answer. But there is a strategy that can be adapted to your moment, your product, and your goals. And here we’ll tell you how to make the best decision, whether you’re looking for quick liquidity or initial volume.
📌 Let’s start with the basics: how do they differ?
Feature | Marketplace | own eCommerce |
Who sells? | Many brands or sellers | only you |
Where is your store? | Within a platform (e.g. Amazon, Zalando) | On your own domain (e.g. jewelrymiamarca.com) |
Who attracts the customer? | The marketplace has its own traffic | You must attract him with marketing |
Who controls the experience? | The marketplace defines rules, design and commissions | You decide everything: design, UX, prices, data |
Do you gain visibility? | High initial exposure | Visibility depends on your effort |
Do you pay commission? | Yes, for each sale (can reach 15%-20%) | Not by direct sale, but you pay for the platform, hosting, etc. |
🛒 This is the purchasing process on each channel
On a Marketplace (e.g., ECI, Amazon, Zalando):
1.The customer enters the platform searching for “minimalist silver ring.”
2.They find hundreds of results, including your product.
3.See reviews, compare prices, check your reputation.
4.Buy with one click within the marketplace environment.
5.You receive the order, manage it, and pay a commission to the platform.
🟢 Advantages: guaranteed traffic, easy to start, quick market testing.
🔴 Disadvantages: high competition, difficult to build loyalty, lower margins.
On your own eCommerce:
1.The customer sees an ad on Instagram, discovers you on TikTok, or is recommended by a friend.
2.They arrive at your store (your website), where you control the design, text, and storytelling.
3.They are seduced by your brand, products, story, and values.
4.They buy directly, without distractions or competition.
5You manage the order, payment, database… and you keep all the margin.
🟢 Advantages: Complete control, personalized experience, loyalty possible.
🔴 Disadvantages: Requires investment in traffic, maintenance, and minimal digital infrastructure.
What factors should you analyze before deciding?
To make the right decision, don’t just think about “where the most sales are.” Think about which model fits your brand today and where you want to go.
1. 🎯 Your immediate objective
-Do you need to validate your product in the market quickly? → Marketplace
-Do you want to build a strong long-term brand? → eCommerce
2. 💰 Your budget and structure
-Do you have limited resources and need to start without large marketing investments? → Marketplace
-Can you invest (even a small amount) in web design, social media, and campaigns? → eCommerce
3. 🛠️ Your operational capacity
-Are you managing everything alone and need a simple channel? → Marketplace
-Do you have a team, or can you outsource part of the process (customer service, shipping, etc.)? → eCommerce
4. 💎 The type of product you sell
-Is it highly sought-after and easily comparable in price? → Marketplace
-Does it have high added value, a history, distinctive design, and powerful storytelling? → eCommerce
🤝 Why do many brands combine both?
Because the smartest thing is not to choose one or the other forever, but to use each channel with a different role:
Objetivo | Canal ideal |
Validate new products or markets | Marketplace |
Capture customers quickly without investing in traffic | Marketplace |
Building community and loyalty | eCommerce propio |
Maximize margins and customization | eCommerce propio |
Example: A jewelry brand started on Amazon to validate its catalog and generate initial sales. With the feedback and initial cash flow, it opened its own online store on Shopify. Today, it uses Amazon as an international showcase and its website as a loyalty channel.
🧠 What if you approach this strategy in phases?
Stage 1: Marketplace as a springboard
Sell on Amazon, Zalando, ECI, etc.
Learn which designs are popular, at what price, and which keywords convert.
Create a community (even a basic one) on Instagram or WhatsApp.
Stage 2: Build your own eCommerce store.
With what you’ve learned, design a simple yet coherent website.
Add brand value, curate the experience, and offer exclusive products.
Start capturing customer data and building relationships.
Stage 3: Optimize both channels according to your strategy.
Marketplace as an acquisition channel.
eCommerce as a loyalty and high-margin channel.

- Your starting point
- Your brand objectives
- Your ability to build a digital experience
The important thing is to build a meaningful, profitable, and scalable brand
