I spent years on the inside of marketplace economics, running media for eBay across eleven markets, including the campaign this blog opened with, which gives me a specific vantage point on the advice every brand hears now: get on the marketplace, that is where the customers are. The advice is correct. The customers are there. What the advice leaves out is the nature of the arrangement, and the nature of the arrangement is a lease. The marketplace owns the location, sets the terms, raises the rent on its own schedule, and keeps the one asset that appreciates: the customer.
Run the actual take-rate math, because most brands never total it. A referral fee around fifteen percent. Fulfillment fees if you use the marketplace's logistics. And then the line that has grown fastest: advertising, because organic marketplace visibility has been methodically converted into paid placement, the same enclosure movement I described in the commerce media post viewed from the seller's side of the counter. Stack them and a brand's effective take rate on marketplace revenue routinely lands between thirty and forty-five percent, before returns. A brand celebrating marketplace growth at a forty percent all-in take rate is celebrating a wholesale business with retail bookkeeping, and the dashboard that reports marketplace revenue without reporting the stack is telling half a story with a bow on it.
The asset that never shows up on the invoice
The fees are the visible rent. The invisible rent is the customer relationship, and it is the more expensive one. A marketplace sale delivers revenue and withholds everything that makes revenue compound: the email address, the purchase history, the ability to launch your next product to the people who bought your last one. Your buyer is the marketplace's customer, shown your competitors at every visit, retargeted by the platform with the category you taught it she wants. This is the OTA arrangement generalized to physical goods: the intermediary that introduces you to a customer once, then charges you for every subsequent introduction to the same person, forever. And because the marketplace sees the whole category's data while you see only your slice, every negotiation, every pricing decision, every new product bet happens against a counterparty holding your cards and everyone else's.
None of this argues for leaving. For most consumer brands the marketplace is where discovery happens, the velocity engine no DTC site matches, and refusing it is refusing distribution out of principle, which is not a strategy, it is a pout with a P&L. The argument is for entering with a portfolio logic instead of a growth-at-any-register logic. The marketplace's job in the portfolio: discovery, velocity, the long tail of buyers you would never profitably acquire directly. The owned channel's job: margin, relationship, replenishment, the launchpad. Products and prices should differ across the two on purpose, exclusive bundles and sizes on the DTC side, so the marketplace introduces the brand and the brand's own channel graduates the customer.
The test is one question
Here is the diagnostic I use, and it takes one meeting: what share of your revenue comes from customers whose contact you own? Not channel revenue split, customer file ownership. Brands cross a quiet threshold when the marketplace share of revenue climbs past the point where the marketplace is effectively their landlord, category manager, and largest marketing vendor simultaneously, and most cross it without ever making the decision, one good quarter at a time. The number itself matters less than whether anyone in the company can produce it, because a brand that tracks file ownership makes different daily choices: package inserts that earn a registration, warranty and replenishment programs that create a direct reason to exist, launch sequencing that gives the owned channel first access. Each is small. Together they determine whether, five years in, the brand has a customer base or a landlord reference.
The objection is that fighting for the direct relationship annoys the marketplace, and the marketplaces do notice sellers who treat them as a discovery layer. But the marketplace is not sentimental about you either; its house brands are trained on your sales data, and your shelf position lasts exactly as long as your economics serve its economics. That is not villainy. It is a landlord being a landlord. Lease accordingly, build equity somewhere you own, and never confuse a good location with a deed.
