Selling on a marketplace or building your own online store
Marketplaces give fast access to an audience but take a cut of margin and customer control. Here is when a standalone site is worth it, and when the marketplace alone is enough.
What a marketplace gives you
Ready-made traffic, platform trust, built-in logistics and payments — you can start selling within days without any development. For testing a new niche, that is often smarter than investing in a site first.
The downside: you compete on price alongside dozens of similar sellers on one shelf, and the platform can change fees or its ranking algorithm at any time.
What your own site gives you
Full control over price, brand, customer data and repeat sales. On your own site you can build a list for retargeting and email/messenger campaigns, which a marketplace does not allow.
The economics are more transparent: acquiring fees are noticeably lower than marketplace commissions, and over time organic search traffic lowers customer acquisition cost.
The real math: fees vs. development cost
Marketplace commissions on average run substantially higher than payment processing fees on your own site. At sufficient sales volume, the difference pays back the site's development cost within months.
That said, a site requires ongoing investment in traffic — ads or SEO — while a marketplace partly solves customer acquisition itself through internal search.
A combined strategy is usually optimal
Most successful sellers use both channels: the marketplace for reach and demand testing, their own site for brand building, repeat sales and B2B customers.
Sync assortment and pricing across channels manually or via integration to avoid confusing customers who see different prices for the same product.
