The first marketplace order felt like proof. After two years of building, someone we'd never met had found our product, trusted it enough to pay, and the money landed in our account by Friday. We did what every founder does: we leaned in.
By the end of that quarter, the marketplace was a third of our revenue. By the end of the year it was closer to half. On every dashboard that mattered to us then — gross revenue, units shipped, growth rate — it was the line going up and to the right. We told investors about it. We told ourselves about it more.
What we did not do, for far too long, was put the channel on a single page and ask it the only question that matters: after everything, what is left?
01 — The number we weren't looking atThe revenue was real. The margin was a rumour.
Marketplace revenue arrives with a kind of confidence that direct revenue doesn't. It's already paid, already shipped, already reviewed. But it also arrives stripped of the costs that don't show up on the order screen — the commission, the fulfilment fee, the returns you eat, the storage you forgot you were renting, the ad spend you needed just to stay visible against your own resellers.
When we finally built the page — one row per cost, one honest number at the bottom — the contribution margin on marketplace orders was a third of what we earned on our own site. We had been working hardest on the channel that paid us least.
02 — What it cost beyond the moneyThe hidden tax on attention.
The financial cost was the obvious one. The quieter cost was attention. Every catalogue update, every pricing change, every promotional calendar now had to be reconciled across a platform whose rules changed without warning and whose customers were never really ours.
We were building someone else’s relationship with our buyer. The reviews lived there. The repeat purchase lived there. The data — who these people were, why they came back — lived there, behind a wall we paid rent on.
- What is the contribution margin after every platform fee, not before?
- Who owns the customer relationship and the data when the sale is done?
- How much of our team's attention does this channel quietly demand each week?
- If this platform changed its rules tomorrow, how exposed would we be?
03 — The decisionWe didn't quit. We right-sized.
The temptation, once you see the number, is to walk away entirely. We almost did. But the marketplace was doing one thing genuinely well: it was finding us new customers we'd never have reached. The mistake wasn't being on it — it was treating a discovery channel like a profit channel.
So we changed the job we gave it. Marketplace became the top of the funnel, not the bottom line. We cut the SKUs we sold there to the ones that introduced people to the brand, and we built the machinery to move those buyers to our own site for everything after the first order. Revenue from the channel fell. The money we kept from it roughly doubled.
The line that stayed in the journal
Months later, reading the entry back, one sentence still holds up. It's the one I'd give any founder staring at a channel that looks like it's winning: measure what you keep, not what you collect. Growth that doesn't survive its own costs isn't growth. It's just motion that feels like it.
