A marketplace takes a commission that can sit near fifteen percent of the sale. Your own store takes nothing per order and charges you for everything else: hosting, photography, payment fees and the advertising that brings strangers to the page. Comparing the commission against zero is the mistake that makes sellers abandon a channel too early.
Compare commission against acquisition cost
Work out what it costs you to acquire one paying customer on your own site, including ad spend, content and the share of ad budget that produces nothing. If marketplace commission per sale is lower than that figure, the marketplace is buying customers for you at a discount. That is a legitimate reason to keep selling there.

Then check what the marketplace withholds besides commission. Promoted placements, storage fees, returns handling and subscription tiers add up. A channel advertising fifteen percent often lands nearer twenty-two once those lines are included, which changes the comparison entirely. Read a full settlement statement rather than a summary.
Owning the customer and renting the customer
The difference between the two channels is not margin, it is the relationship. A marketplace customer can be reached again through the platform, on the platform's terms. Your own store's customer is on a list you control. Rent is convenient and revocable; ownership is expensive and durable. Most sellers need both, in a deliberate ratio.
Practical move: sell identical products on both channels for one quarter and compare contribution per order after every fee. Then compare repeat purchase rate. The channel that wins on first order frequently loses on the second, and the second order is where the profit usually sits.

Channel conflict is real and quiet

Listing the same goods at different prices invites buyers to find the cheaper one and platform algorithms to notice. Keep headline prices aligned and compete on bundles, delivery speed or support instead. Sellers who undercut their own channel by a wide margin often find that the cheaper channel becomes the only one that survives.
