Ecommerce vs Marketplace: What's the Difference?
The difference between ecommerce and a marketplace is who sells. An ecommerce store has one seller: the business that owns it. A marketplace hosts many independent sellers under one storefront and takes a commission on their sales. Ecommerce vs marketplace is really a choice between selling your own products and running a platform for others.
That distinction sounds academic until you're deciding which one to build. Then it sets your costs, your control, and who your customers actually belong to.
What's the difference between ecommerce and a marketplace?
An ecommerce store (sometimes called an ecommerce website) is a single business selling its own catalog online. You buy or make the products, set the prices, own the customer list, and keep the full margin. A marketplace is a business model, not a store: one destination where many independent sellers list their products, and the operator makes money by taking a cut of what those sellers sell.
The gap between the two models is large and growing. Online marketplaces accounted for nearly 30% of global online shopping orders in 2024, and the top 100 marketplaces alone moved about $3.8 trillion in goods that year, up 10% on 2023. The reason is structural: a marketplace grows by adding sellers, and each seller brings their own inventory and audience.
Here's the split, row by row:
| Ecommerce store | Online marketplace | |
|---|---|---|
| Who sells | One business (you) | Many independent sellers |
| Who owns the inventory | You | Each seller |
| How it makes money | Margin on your own products | Commission plus seller fees |
| Who owns the customer | You | Usually the platform |
| The operator's main job | Sourcing and selling products | Recruiting sellers and buyers |
| Startup complexity | Lower: one catalog, one payout | Higher: multi-seller payments and onboarding |
| Examples | Nike.com, most Shopify stores | Amazon, Etsy, eBay |
Read that "who owns the customer" row twice. It's the trade-off nobody warns you about. Sell on a marketplace as a vendor and the platform, not you, owns the buyer relationship.
Ecommerce platform vs marketplace: the trade-offs
People often frame this as "ecommerce platform vs marketplace," but the two aren't opposites. An ecommerce platform (Shopify, WooCommerce, BigCommerce) is the software you use to build a store. A marketplace is a business model you could run on top of that software. Zoom out further and a marketplace is itself one type of platform, a distinction we untangle in platform vs marketplace. So the real question is which model you want, then which tools get you there.
Choosing the store model gives you control and full margin, at the cost of doing everything yourself: sourcing, stock, storage, support. Choosing the marketplace model trades some control for reach. You don't buy inventory or ship most orders, but you take on a harder job: keeping two sides of a market, sellers and buyers, growing at once.
- Ecommerce store strengths: full control of brand and data, full product margin, simpler payments, faster to launch a single catalog.
- Marketplace strengths: no inventory to buy, catalog grows as fast as you recruit sellers, revenue scales without proportional stock or storage cost.
- The catch on each: a store's growth is capped by what you can source and stock; a marketplace is dead until both sides show up, the classic chicken-and-egg problem.
What is an ecommerce marketplace?
An ecommerce marketplace is an online store where multiple third-party sellers sell to buyers through one shared storefront, and the operator takes a commission on each sale. Amazon, Etsy, and eBay are the household names. The term also covers hybrids: a retailer that sells its own products and hosts outside sellers on the same site.
That hybrid is more common than most people realize. Amazon is the cleanest case: it started as an ecommerce retailer and opened to outside sellers in 2000. Today third-party sellers make up about 61% of the units sold on Amazon. The store never went away. It just became a small part of a much larger marketplace.
When should you choose a marketplace over an ecommerce store?
Pick the model that matches what you actually have. If you have products, margin, and a clear brand, a store is faster and simpler. If you have (or can gather) a supply of sellers and a reason for buyers to come to one place, a marketplace can grow well past what your own inventory ever could.
Choose an ecommerce store when:
- You make or source your own products and want full margin.
- The customer relationship and your brand are the point.
- You want the shortest path from idea to first sale.
Choose a marketplace when:
- You'd rather curate and connect sellers than hold stock.
- Your value is the assortment, the audience, or the niche, not one catalog.
- You can commit to recruiting and supporting sellers, because that becomes the job.
There's real money in the second model. A marketplace can charge commissions, listing fees, subscriptions, or ads, which is how marketplaces make money in ways a single store can't. But none of those revenue lines exist until sellers do.
Do you have to choose? Running both at once
No. The marketplace vs ecommerce decision isn't permanent, and it isn't exclusive. Plenty of businesses start as a store and layer a marketplace on top once they have traffic, exactly the path Amazon took. You keep selling your own products and invite others to sell alongside you, on the same domain and checkout.
On Shopify this is a well-worn setup. Garnet, the multi-vendor marketplace app for Shopify, adds vendor accounts, automatic product syncing, per-order splitting, commissions, and payouts to a standard Shopify store, so the storefront your customers already know quietly becomes a marketplace. We break the mechanics down in our guide to building a multi-vendor marketplace, and the money side in how split payments work.
Real stores run this way today. MadeIt sells handmade goods from 800+ artisans across 25,000+ products with a team of two, on an ordinary Shopify store. If you're weighing the tooling, our roundup of the best marketplace platforms compares the honest options, and is Shopify a marketplace answers the question that usually comes next.
FAQ
What's the difference between an online marketplace and an ecommerce website?
An ecommerce website sells one company's products, and that company controls the brand, pricing, and customer data. An online marketplace is a single storefront where many independent sellers list their own products, and the operator earns a commission instead of a product margin. Online marketplace vs ecommerce comes down to one seller versus many.
Is Amazon ecommerce or a marketplace?
Both. Amazon began as an ecommerce retailer selling its own inventory and became a marketplace when it opened to third-party sellers in 2000. Those sellers now account for about 61% of units sold. It's the clearest example of an ecommerce website that grew into a marketplace without giving up its own store.
Is a marketplace more profitable than an ecommerce store?
Not automatically. A marketplace earns commission on many sellers' sales without buying inventory, so margins can scale further. But it only works once you have enough sellers and buyers on both sides. An ecommerce store earns full product margin from day one, with far less to coordinate.
Can one business run both an ecommerce store and a marketplace?
Yes. Many brands sell their own products and host third-party sellers on the same storefront, the way Amazon does. On Shopify, a multi-vendor app adds vendor accounts, order splitting, and payouts to a normal store, so you keep selling your catalog while others sell alongside you.
