Whatnot in Polar: marketplace revenue, net of the fees.
Whatnot reports Whatnot. It shows you gross sales in its own dashboard, on its own definitions, and it cannot see your store, your ad spend or your cost of goods. Bring orders, fees and returns into Polar and marketplace revenue lands on the same P&L as DTC, with the commission already taken out.

Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Whatnot in plain language. It reads the API, writes the connector and pipes the data into your warehouse as governed data, in minutes.
Worth knowing: what lands depends on what your seller account exposes. Orders, fees and returns are the usual set, and history is limited to what the API will give back. You choose the fields you want, or import everything the API exposes.

Fees netted, blended automatic
Real margin, not gross.
Polar nets the commission, fulfilment charges and returns out and blends the result with Shopify, down to SKU and market, so marketplace profit is calculated on real cost rather than on the gross figure the channel reports.
3
One P&L across channels the payoff
DTC and marketplace, together.
Whatnot sits next to your DTC revenue on one blended P&L, so you see channel mix and true margin instead of switching to a separate seller dashboard to guess at it.
Side by side
Whatnot reports Whatnot. Your business is more than Whatnot.
Whatnot shows the channel in isolation, gross numbers, its own commission, its own dashboard, and it cannot see your DTC store or the rest of your stack. So the real question, what did Whatnot actually make me next to everything else, has no home. Polar is that home.

The channel sits in its own dashboard, apart from your store.
Whatnot blended onto the same P&L as your DTC revenue.
No view of which SKUs or markets actually earn there.

Nothing reconciles the channel against net profit.
Every marketplace dollar inside contribution margin and net profit.
The Gap
The connector is only half of it.
Once Whatnot orders, fees and returns are netted against your store data inside Polar, you can use the result wherever you already work. Ask Polar in plain language, pull it live through the Polar MCP, or schedule it into the report your team reads every morning.
