A wooden toy maker listed on a marketplace in November and turned over more than a full year of sales from his own website. In February he called, worried: the platform had changed its returns policy, the commission had gone up, and a competitor was selling a near identical item 12 percent cheaper and sitting above him in the results.
Both halves of that story matter equally. A marketplace gives access to buyers a small brand cannot reach alone. That same marketplace controls the rules, the pricing, the visibility and, to a large extent, the customer relationship. A company relying on it alone is building on land it does not own.
This article covers how to use the channel sensibly: when it makes sense, what is actually left after all the fees, and how to combine it with your own online store.
How the marketplace channel works
A marketplace gathers many sellers in one place and gives buyers search, comparison, payment and delivery. You upload products, the platform supplies the traffic, and in return it takes a percentage of every sale.
The difference from your own store is fundamental. In your own store you pay for traffic but keep all the revenue and the customer data. On a marketplace traffic arrives ready made, but you pay commission and receive limited buyer information.
Which platforms matter
Large regional platforms cover the widest audience for standard consumer goods. International platforms open access to markets abroad but require solving delivery, returns and language. Niche platforms for handmade goods, books or parts have smaller volume but a far better matched audience.
The choice is not between them but by one criterion: where your customers are already searching for a product like yours.
When a marketplace makes sense and when it does not
It makes sense for products with clear existing demand, with margins that absorb commission, when you can allocate separate stock to the platform, and when you want a fast test of whether the product sells at all.
It does not make sense at very low price points where commission eats the profit, for products needing explanation or consultation, for highly seasonal goods with awkward logistics, and when you cannot answer messages within hours.
Comparing the two channels
| Metric | Marketplace | Own online store |
|---|---|---|
| Initial traffic | Available immediately | Takes months to build |
| Cost per sale | 8 to 25 percent commission | Advertising plus upkeep |
| Customer data | Limited | Full, yours |
| Control over price and presentation | Limited | Full |
| Brand building | Weak | Strong |
| Risk of rule changes | High | None |
| Repeat sales | Difficult | Possible via email |
The table explains why most successful retailers run both. The marketplace brings volume and new buyers, the own store brings margin and repeat orders.
What the platform takes from your sale
Commission usually runs between 8 and 25 percent depending on category. On top of that come payment processing fees, possible storage fees if you use the platform's logistics, and spend on advertising inside the platform, without which visibility in competitive categories is poor.
The exercise is simple. Take the price, subtract commission, delivery, packaging, cost of goods and the expected return rate. If less than 15 percent remains, the channel only works at high volume and is exposed to any rule change.
Preparation before the first upload
The product feed is the foundation
The feed is the file describing your products to the platform: title, description, price, stock, images, category, attributes. Its quality determines whether the product gets found at all.
The title should carry brand, product type, key characteristic and size, in that order. Attributes get filled in completely even when optional, because they feed the filters buyers use to narrow their choice. A product with no colour or size recorded simply does not appear when filters are applied.
Images decide the click
First image on white, product filling most of the frame, at least five shots from different angles, one in real use and one showing dimensions. That is the difference between a listing that gets opened and one that gets scrolled past.
Stock synchronisation
The most expensive mistake is selling an item you no longer have. Platforms penalise cancelled orders with reduced visibility and, in serious cases, suspend the account. If you sell in more than one place, stock has to update automatically rather than by hand once a day. This is where automation connecting warehouse, store and feed earns its keep.
Winning visibility on a marketplace
Platform algorithms differ, but the common factors repeat: order acceptance and fulfilment rate, dispatch speed, customer ratings, sales volume on the listing, price competitiveness and description completeness.
The first sales are hardest because the listing has no history. A launch therefore usually involves a slightly sharper price and internal advertising until the listing accumulates reviews. Price can be corrected upward afterwards.
Reviews are not cosmetic
The gap between 4.2 and 4.8 stars shows up directly in sales. Ask for a review in a note with the parcel, respond to negative ones publicly and calmly, and fix problems before the customer writes anything.
Combining with your own store
The marketplace is an acquisition channel, your site is where value is built. Every parcel is a chance to move from one to the other: a card with a discount code for the next order, a warranty registration, a short usage guide hosted on your own page.
Check the specific platform's rules, since directly inviting customers to shop elsewhere is usually prohibited. The permitted space is still enough to keep your brand in the buyer's mind.
In parallel, your own website should carry the same products with better descriptions, and SEO work should surface it for searches where the buyer already knows what they want.
Common mistakes
The same description everywhere. Every platform has its own length and structure requirements. Copied descriptions rank poorly.
Pricing without doing the maths. Listing at your own site price without adding commission means selling at a loss.
Slow message replies. Many platforms measure response time and fold it into the seller rating.
No stock buffer. Keep a few units in reserve so you do not sell the last item in two places at once.
Total dependence on one channel. If 90 percent of turnover comes from one platform, a rule change there threatens the whole business.
Frequently asked questions
What does a marketplace take from each sale
Depending on category, commission runs between 8 and 25 percent, plus payment fees, possible storage and internal advertising. A realistic calculation requires subtracting all of those before judging whether the channel is profitable.
Can I sell on a marketplace and my own store at once
Yes, and that is the recommended approach. The conditions are automatic stock synchronisation and a deliberate pricing policy so the two channels do not compete in ways that damage both.
What happens if the platform suspends my account
Sales stop immediately and funds are typically held for a set period. That is exactly why your own store and an email list are not a luxury. They are the insurance that lets you keep trading.
Is advertising inside the platform worth it
In competitive categories a new listing is effectively invisible without it. The sensible approach is a capped budget for the first weeks until the listing gathers sales and reviews, then reducing spend and watching whether the position holds.
How do I compete with cheaper sellers
Not on price, if you cannot sustain it. What works is a better description, more and higher quality images, faster delivery, reviews, and bundles that make direct unit price comparison impossible.
Next step
A marketplace is a good acquisition channel and a poor sole channel. The most stable configuration has the platform bringing volume and new buyers while your own store brings margin, data and repeat orders.
