Drive Profitability by Comparing Channel Performance: The WhatSales Edge

15 October 2026

Selling on five marketplaces doesn't mean you have five equally good channels, it usually means you have two strong ones, two mediocre ones, and one that's quietly losing money once every fee is accounted for. Most sellers can't say which is which, because each channel's numbers live in its own dashboard.

Why channel comparisons are usually wrong

Comparing channels on revenue alone flatters the ones with the highest fees and the most aggressive advertising, because neither shows up in a simple sales total. A channel doing half the revenue of another can easily be the more profitable one once fees, ad spend and return rates are factored in, but that only becomes visible when every channel is measured the same way, side by side.

Our /performance dashboard puts every connected marketplace on one screen with the same metrics: sales, fees, ad spend, refunds and net margin. Amazon, eBay, Walmart, Shopify, Temu and Tesco all measured the same way, so the comparison is actually fair.

What a fair comparison lets you do

  • Shift ad budget toward the channel with the best margin, not just the best sales
  • Spot a channel that's growing revenue while quietly losing money
  • Decide with real numbers whether a new marketplace is worth the operational overhead
  • Stop treating every channel as equally important when they aren't

The edge isn't selling everywhere, it's knowing which "everywhere" is actually worth the effort. You can /book-a-demo to see your own channels compared side by side.
