Choosing Where to Sell: How to Pick the Right Channels for Your Products

Deciding where to sell is one of the highest-leverage choices you'll make, and one of the easiest to make badly. The advice you hear is usually 'be everywhere' — list on Amazon, Walmart, your own store, and every marketplace you can reach. But each channel carries a different fee structure, a different audience, a different fulfillment model, and a different cost in time and attention. A channel that prints money for one seller's products can be a margin trap for another's. The right way to choose isn't by hype or by what a competitor is doing — it's by running each channel through the same filter: does it reach the right buyer, and does the unit economics leave a profit worth the effort? Spreading yourself across channels that don't pay is how sellers stay busy and broke.

Every channel has a different cost to serve

The headline commission is only part of the picture. Each channel layers on its own combination of referral or commission fees, fulfillment costs, advertising norms, and operational overhead — and the same product nets a very different profit depending on where it sells. A marketplace with a large built-in audience may charge more in fees but cost you less in traffic generation; your own store keeps more of the sale but forces you to pay for every visitor. Before you can compare channels, you have to compute the true net margin on your specific SKUs in each one. A channel comparison done on revenue alone, or on commission alone, leads you to the wrong answer with confidence.

A framework for choosing

Run every channel you're considering through the same questions before committing inventory or attention to it.

• Audience fit — does the channel's shopper actually buy your category, or are you forcing a product into the wrong crowd?
• Net margin per SKU — after that channel's full fee and fulfillment stack, does each product still clear a profit worth having?
• Fulfillment fit — can you meet the channel's delivery expectations profitably, or does fast shipping erase your margin there?
• Effort and overhead — does the channel demand listing work, support, and ad management you can sustain without starving your core channel?
• Competitive density — is the channel saturated in your category, or is there room to win the Buy Box and visibility?

Start focused, expand on evidence

The sellers who win at multi-channel rarely got there by launching everywhere at once. They proved one channel profitable, built the operational muscle to run it well, then expanded to the next where the numbers and the audience justified it. Adding a channel multiplies your operational load — more listings to maintain, more inventory to allocate, more customer expectations to meet — so each new one has to earn its place. Treat expansion as a series of tested bets, not a land grab. A second channel that drains attention from a profitable first channel can cost you more than it adds.

Allocate inventory to the channel that pays

Once you're on more than one channel, the question shifts from 'where to sell' to 'where to send the next unit.' The same product can earn a different net margin on different channels, and your limited inventory should flow to wherever it nets the most after that channel's fees and costs — adjusted for velocity, so you're not maximizing margin per unit while starving your fastest mover. That decision requires seeing profit per SKU per channel side by side. Sellers who allocate by gut tend to overfeed the channel that feels biggest rather than the one that actually pays best.

Frequently asked questions

Should I just sell on every channel I can?

Rarely. Each channel adds fees, fulfillment costs, and operational overhead, and a channel that's profitable for one seller can be a margin trap for another. Run each one through the same filter — audience fit, net margin per SKU, fulfillment fit, effort, and competition — and add it only if the numbers justify it. Spreading across channels that don't pay keeps you busy without making you money.

How do I decide which channel gets my limited inventory?

Send the next unit to wherever it nets the most after that channel's fees and costs, adjusted for how fast it sells there. The same SKU often earns a different net margin on different channels, so allocating by which feels biggest is a mistake. Look at profit per SKU per channel side by side, and weight toward the channel that combines strong margin with healthy velocity.
