Marketplace or Your Own Online Store: Where You Will Earn More in 12 Months

Short answer: a marketplace is cheaper at the start and at low volume — you rent traffic and logistics. Your own store wins where you sell repeatedly to the same customer: margin without commission, the customer base stays yours, and you control the price. For most small and mid-size businesses the right strategy is not “either/or” but 70/30: the marketplace for the flow of new buyers, your own site for second purchases and branded demand.

What “marketplace fees” really consist of

Owners count only the percentage per sale; the real bill is usually twice as high:

• commission on turnover — category-dependent, typically in the 10–20%+ range;
• logistics and storage — intake, placement, last mile; slow movers pay for air;
• acquiring and returns — you pay for cancelled and returned orders twice (there and back);
• internal advertising, without which your card is invisible — effectively your CPM, just inside their app;
• price dumping: you compete not only with the same product but with someone else’s warehouse at “stock minus 5%”.

Your own store adds a different line: customer-acquisition cost (ads, SEO, content) and site maintenance. But that money buys what a marketplace never gives you: customer contacts, purchase history and the value of the repeat order.

The table worth keeping in mind

Parameter	Marketplace	Your own store
First sales	days	6–12 weeks to full launch
Commission per sale	~10–20%	0 (acquiring 1.5–3%)
Who “owns” the customer	the platform	you
Repeat sales	through the platform, expensive	email/messenger, nearly free
Price control	limited (dumping)	full
Traffic	rented from the platform	you build it
Behavioural data	almost none	full analytics
Dependence on platform rules	maximal (ban, tariff changes)	minimal

Simple arithmetic on one product

Take a product priced at 1,000 ₴ with a 500 ₴ cost.

• Marketplace: commission + logistics + internal ads eat roughly 200–300 ₴ per sale → your margin is 200–300 ₴, the customer is anonymous to you, and you do not plan a second order — they will pay the platform again.
• Your own site: acquiring costs about 25 ₴, but 150–300 ₴ goes to winning the first customer. Margin on order one ≈ the marketplace case. The difference starts with orders two and three: acquisition cost divides across purchases while margin compounds.

That is why marketplaces are perfect for one-off products and demand testing, and your own store is critical in repeat-purchase categories: cosmetics, pet food, consumables, size-based apparel, kids’ goods, auto parts.

When the marketplace is objectively better

• the product is new and demand is unproven — the platform tests it without an ads budget;
• low ticket, mass assortment, where “the platform’s warehouse” logistics beat yours;
• you manufacture rather than retail: B2C functions (site, support, returns) are not your business.

When your own store stops being optional

1. Repeat purchases are your core. If customers return within 12 months, every commission point is a direct subsidy of someone else’s profit.
2. Dumping is choking you. On a platform you compete on price; on your own site you compete on brand, service and expertise — content no one can “copy as a product card”.
3. You depend on one account. A tariff change, a block, an anonymous competitor complaint — and the channel zeroes out in a day. We have had clients who lost 80% of revenue that way overnight.
4. B2B and big tickets. A legal entity needs a price list, credit terms, custom conditions and a manager — marketplaces do not teach that.

What your store needs so it does not starve

A store without a traffic channel is a warehouse without a window. The minimum for the first 90 days:

• SEO foundation — category clusters and product pages (full plan: SEO for a new site: a 90-day strategy);
• a fast mobile two-step checkout with clickable fields and autofill;
• return paths: abandoned cart, messenger reminder, post-purchase email chain (how to start selling online: 5 steps);
• analytics from day one: GA4, goals, e-commerce events — otherwise you cannot tell “the store does not work” from “the traffic is wrong”.

From DEXA practice

Solomia Beauty sold through platforms and Instagram. We built a store with stock sync, a CRM client card and two-step checkout — conversion +180% in 4 months, but the main thing: the customer base became an owned asset and repeat sales stopped costing ad money. In the Verkhava case it was the opposite — services: booking on the own site replaced aggregators and removed 18% of aggregator commissions in a season.

FAQ

Bottom line

“Marketplace or own store” is decided by one criterion: is the purchase repeatable. One-off demand — rent the platform. Repeat demand — build your own channel before the commission becomes your biggest expense line.
