Selling on marketplaces versus your own store: whose customer

Introduction

Marketplaces offer immediate access to enormous demand and take a share of every sale. Your own store costs nothing per transaction and has no visitors unless you produce them.

The choice is usually framed as a fee comparison, which misses the point. The real difference is who owns the customer relationship, and that determines what the business is worth in five years.

1. Selling on marketplaces versus your own store is a question of ownership

Both channels have a real cost; they are just charged differently.

A marketplace charges commission and keeps the customer data. Your own store charges you the cost of acquiring traffic and lets you keep the relationship. One is rented demand, the other is owned audience, and the trade-off is genuine.

2. Compare the true cost of both, not the commission alone

The headline comparison is misleading in both directions.

Marketplace costs include commission, listing fees, fulfilment charges, storage, advertising to be visible, and returns. Your own store costs traffic acquisition, platform fees, payment processing and the labour of running it. Calculate both fully before concluding anything.

3. Recognise what a marketplace is genuinely good for

There are situations where it is clearly the right answer.

Testing whether a product sells at all, reaching customers you cannot yet acquire, clearing surplus stock, and generating early cash flow. For a new seller with no audience, the commission buys demand that would otherwise cost more to create.

4. Understand the platform risk you are accepting

A marketplace can change your business overnight and you have no say.

Fee increases, algorithm changes, a suspended listing, a policy alteration, or the platform selling a competing own-brand version of your product. A business entirely dependent on one marketplace is a business with a single point of failure it does not control.

5. Use both, and be deliberate about what each one does

For most sellers this is the correct answer.

Marketplaces for reach and discovery; your own store for margin, repeat purchase and control. The mistake is drifting into that arrangement without a plan, rather than choosing which products and which purpose belong on each channel.

6. Convert marketplace buyers into your own customers where permitted

Every platform restricts this, and there is usually still something you can do.

Package inserts, product registration, warranty or guarantee signup, and instructions that lead to your site. Understand the rules and work within them, because moving even a modest share of buyers to your own store changes the economics substantially.

7. Do not undercut your own store on the marketplace

A common and self-defeating pattern.

If your marketplace price is the same or lower, there is no reason for anyone to buy direct, and you are paying commission on customers who would have come to you anyway. Reserve bundles, exclusives or better terms for your own store.

8. Watch what each channel does to your operations

The two are not operationally equivalent.

Marketplaces impose dispatch deadlines, performance metrics, packaging requirements and returns policies you must follow. Those obligations consume attention and can degrade the service on your own store if you are not resourced for both.

9. Track contribution and repeat rate by channel

The figures that answer the strategic question.

Margin after all channel costs, and how many buyers from each channel purchase again. Marketplace customers frequently never return to you specifically, while direct customers do — which means the same revenue is worth quite different amounts depending on where it came from.

Conclusion

Understand that you are choosing between rented demand and owned audience, and that the fee comparison is the least important part of the decision.

Cost both channels fully rather than comparing commission alone, use marketplaces for reach, testing and cash flow, recognise the platform risk of depending on one, run both with a defined purpose for each, convert marketplace buyers within the rules, avoid undercutting your own store, account for the operational obligations each channel imposes, and measure contribution and repeat purchase rate separately by channel.
