eBay shows eBay. Your business is more than eBay.

eBay reports in isolation, gross numbers, its own fees, its own dashboard, and it cannot see your DTC store or the rest of your stack. So the real question, what did eBay actually make me next to everything else, has no home. Polar is that home.

eBay on its own

  • eBay numbers live apart from DTC.
  • Gross sales, with fees buried in separate reports.
  • No blended view of channel mix or true margin.
  • Nothing reconciles against your real P&L.

eBay with Polar

  • eBay resolved as a channel, blended on one P&L.
  • Fees netted out, so margin is real.
  • Channel mix and profit next to every other channel.
  • Every eBay dollar reconciled into contribution margin.

Resolve as a channel day one

Via Shopify, nothing to set up.
If eBay orders route through Shopify, Polar already resolves them as the eBay sales channel. Check Acquisition by channel to confirm.

Fees, payouts, SKU detail.
For native depth, eBay fees, payouts and product-level detail, the AI data engineer builds a direct connector.

The Gap

The connector is only half of it.

Once your eBay orders and fees are clean and attributed inside Polar, you can use them wherever you already work. Ask Polar in plain language, pull them live through the Polar MCP, or schedule a snapshot into the report your team reads every morning.

Featured Use Case

Channel profit, not channel revenue.

Channel profit, not channel revenue

eBay looks fine in its own dashboard until you try to compare it to your DTC store: the numbers are gross, the fees are scattered, and there is no way to see channel profit next to Shopify on the same basis. Polar resolves eBay as its own sales channel, nets the fees out, and blends it into one P&L, down to SKU and channel with a custom connector. The question stops being how much did eBay gross and becomes what did eBay actually keep, and how does that compare to DTC.

What makes it real

Fees netted out. eBay fees pulled and subtracted, so channel margin is real, not gross.

Blended by channel. eBay sits next to DTC and every other channel on one P&L.

Ask Polar, in plain language. “Show eBay margin after fees by SKU, next to DTC.” No SQL, no export.
