Ecommerce website vs. marketplace: Why most sellers need both
Webstores and marketplaces aren’t rivals. Most successful sellers use both: marketplaces to reach shoppers who are already searching, and their own website to build a brand, own the customer relationship, and protect margin. Even digital-native brands that built their name on direct-to-consumer sales now sell on Amazon and other marketplaces alongside their own stores.
This guide compares an ecommerce website (your own webstore, built on a platform such as Shopify or BigCommerce) with online marketplaces (such as Amazon, eBay, Walmart, Etsy, and TikTok Shop). It explains why selling on both works, how to choose where to start, and what you need to run both without doubling your workload. If you’re still choosing a platform for your own store, see our guide to what ecommerce platforms are.
The short answer: start where your customers are and where your strengths lie. If you need demand quickly, begin with a marketplace. If your brand, margins, and repeat purchases matter most, begin with your own site. Then add the other, so each channel supports the other.
What’s the difference between an ecommerce website and a marketplace?
An ecommerce website is a store you own and control. You choose the design, the content, the pricing, and the customer experience, and you’re responsible for attracting traffic. A marketplace is a third-party platform where many sellers list products and shoppers come to compare and buy. The marketplace brings the traffic, sets the rules, and takes fees in return.
| Factor | Your own website | A marketplace |
|---|---|---|
| Traffic and discovery | You generate it through search, ads, email, and social | Built-in shopper demand, and you compete on the listing |
| Brand control | Full control of design, content, and experience | Limited, and your listing sits next to competitors’ |
| Customer data and relationship | You own the data and the email list | The marketplace controls most customer data |
| Fees | Platform subscription, payment processing, and marketing spend | Referral, fulfillment, and advertising fees, which vary by marketplace |
| Speed to launch | Slower, because you have to build traffic | Faster, because shoppers are already there |
| Risk | You control the channel | Account suspensions and policy or fee changes can hit sales |
| Operations | One system to manage | Each marketplace has its own rules, data requirements, and shipping standards |
5 reasons to sell on both
1. Marketplaces put you where shoppers already are
Marketplaces handle a huge share of online buying. Digital Commerce 360 projected that the world’s top 100 online marketplaces would handle more than $3.8 trillion in sales in 2024. Many shoppers start their product searches on a marketplace rather than a search engine, so a listing there puts you in front of people who are ready to buy.
Selling on several channels is now the norm. In Linnworks’ State of Commerce Ops 2026 report, the average mid-market retailer sold on more than four marketplaces or channels (4.15 in the UK and 4.25 in the US). Rather than relying only on your own marketing budget, you can borrow the audience and trust a marketplace has already built.
2. Marketplace sales can support your own site
Sellers often worry that marketplaces will cannibalize their website sales by drawing attention away from their own listings. In practice, the two channels often feed each other. Shoppers discover a brand on a marketplace and later search for it by name, and others visit a brand’s site first and then check marketplaces for prices and options.
The effect varies by business, so measure it. After you launch on a marketplace, track branded search, direct traffic, and webstore orders alongside marketplace sales, and compare the results with the period before launch.
Marketplaces are also low-cost testing grounds. You can check demand for a new product, or reach a type of buyer who doesn’t visit your site, before investing in your own marketing.
3. Selling on multiple channels reduces concentration risk
You never want to be without an active sales channel, and relying on one makes that more likely. A single channel can disappear or shrink for reasons outside your control:
- A marketplace suspends your account or a listing, sometimes in error
- Fees, advertising costs, or policies change
- Demand shifts, a platform’s algorithm changes, or a competitor undercuts you
- A supply or fulfillment problem hits one channel harder than the others
Diversifying across your own website and several marketplaces spreads that risk, so a problem on one channel doesn’t stop the business. For a closer look at what to weigh before adding a marketplace, see our guide to the 6 things to consider before selling on a marketplace.
4. Marketplaces help you protect your brand
Your competitors, resellers, and unauthorized sellers may already be on marketplaces. Some shoppers won’t realize they’re buying from a different seller, and may blame your brand for a poor delivery or product experience on a listing you don’t control.
By being present, you can take charge of your own listings. Several marketplaces offer brand programs, such as Amazon Brand Registry and eBay’s Verified Rights Owner (VeRO) program, that give brand owners more control over listing content and help them report unauthorized listings. Check who is already selling your products and where, especially as brick-and-mortar retailers move stock online.
5. With the right technology, you can manage both
Running a webstore and several marketplaces gets difficult fast without a system that handles:
- Product information management to format product data correctly for each channel and prevent listing errors
- Listing management to create, edit, and group listings (such as variations or kits) on multiple channels without repeating work
- Inventory sync to update stock levels across channels quickly and avoid overselling
- Inventory thresholds to protect your last few units of a product
- Multi-warehouse management to route orders to the right warehouse or fulfillment center
- Analytics and forecasting to understand profitability across channels, spot your best and worst SKUs, and forecast demand from centralized data
Linnworks brings these together. With multichannel selling, inventory management, and listings management in one place, and 100+ integrations with global sales channels, you can add a new marketplace without rebuilding your process each time.
Know each channel before you add it
Sellers often add a channel, then feel let down because it doesn’t perform like their first one. Marketplaces aren’t interchangeable. They differ in who shops there, how listings are found and ranked, how fees are structured, how much control you have over the customer relationship, and what content and shipping standards you must meet. Treating eBay like Amazon, or the reverse, is a common mistake.
Before you launch on any new channel, answer five questions:
- Who shops here, and why?
- What are the fees and listing requirements?
- How are listings ranked and discovered?
- What shipping and performance standards apply?
- What does success look like in the first 90 days?
Set specific expectations and processes per channel instead of taking a blanket approach. Our guide to succeeding on online marketplaces goes deeper on each.
Fulfill with a mix, not a single method
Don’t depend on one fulfillment method any more than you depend on one channel. Marketplace fulfillment programs are convenient, but some marketplaces restrict or don’t accept orders fulfilled through a competitor’s network, and relying on a single program leaves you exposed if something goes wrong. Check each channel’s fulfillment rules before you commit.
A healthy mix of your own fulfillment and a third-party logistics provider gives you more control over packaging, shipping, and order flow. It also protects you from delistings and errors on channels with strict rules. See our guide to 3PL warehouse logistics for how to choose a partner.
Shipping speed matters too, because fast delivery helps you win the sale on many channels. You don’t have to offer it everywhere at once. Start with a few key regions, place inventory in fulfillment centers close to your customers, and expand as you grow. Shipping management software can help you show fast delivery options only where you can meet them.
How to decide where to start
- You need demand fast, or you’re testing a product: Start with one or two marketplaces that match your products.
- Your product is brand-led, with repeat purchases and strong margins: Start with your own site, then add marketplaces for reach.
- You already sell on one channel: Add the other, so each supports the other.
- Your operations team is stretched: Keep to one or two channels and automate inventory and orders before you expand.
In summary
Shopping journeys are fragmented across your website, marketplaces, and social platforms. Sellers who show up in several places reach more buyers, spread their risk, and keep their brand in view. Your own website builds your brand and your customer relationships. Marketplaces bring reach and speed.
Adding a channel doesn’t have to mean doubling your work. With the right system, you can manage them from one place. Request a demo to see how Linnworks helps you sell on your website and marketplaces without the manual work.
