Your Own Store or Marketplaces? The 2026 Comparison

The cost maths

The invisible cost of marketplace selling is not limited to commission. The commission band varies by category, and on top of it come shipping deductions, mandatory campaign participation, on-site advertising and return rates. Added together, these push your net margin well below what you expected.

On your own site the picture is different: one upfront investment and a relatively small monthly running cost. In exchange, the full margin on every order stays with you, and the payment arrives without deductions beyond the payment-gateway fee.

Run the calculation this way: find the percentage of monthly revenue that evaporates on the marketplace and multiply by twelve. For most SMBs that number is larger than the cost of building their own store.

Brand or market stall?

A marketplace is a market stall. The crowd is already there, and that is a real advantage. But the customer remembers the platform, not you; on the second purchase they search for the same product and your competitor appears.

Your own site is your shop. Repeat purchases, email lists and brand loyalty accumulate there. More importantly, the customer data is yours: you know who bought what, you can reach them directly, and you run promotions on your own terms.

A marketplace can change the rules overnight. Commission rates, the ranking algorithm, the shipping deal — none of it is under your control. On your own site you are the only rule-maker.

But do not abandon the marketplace

The point here is not to tell you to leave. Expecting a brand-new store to match marketplace traffic in its first months is not realistic.

The winning setup is this: the marketplace is the shop window, your site is the profit channel. Let new customers arrive through the marketplace; pull the repeat buyers into your own channel.

The cheapest way to do that is a card in the box. Have the QR code lead straight to a reorder page on your site, with a small advantage waiting there — free shipping, a discount on the next order, whatever fits. To the extent marketplace rules permit in-parcel inserts, this is the highest-converting channel you have.

How to manage stock in two places

The biggest practical risk of selling on two channels is a stock mismatch. If an item sold on the marketplace still shows as available on your site, cancellations and bad reviews follow.

The answer is integration: manage stock from one panel so that whichever channel the sale comes from, the count drops everywhere at once. That is why marketplace integration is standard in every e-commerce project we build.

You also need a pricing decision. Being cheaper on your own site is logical — you pay no commission — but some marketplaces expect price parity. Read the rules and give the difference as shipping or a gift rather than as price.

When to move to your own store

There are three signals. Your monthly order count has stabilised — once the swings settle, you have repeat buyers. Your commission bill has reached four figures a month — that money now finances an investment. People search for your brand — if they type your name instead of the product name, leaving that traffic on a platform is waste.

If two of the three are true, it is time. Over a two-year horizon your own store outperforms the marketplace — but only if you actually move the repeat buyers there, not if you build it and wait.
