Amazon Seller Central integration

Amazon in Polar: orders in, real marketplace margin out.

Connect Amazon Seller Central and gross sales, orders, fees, refunds and costs flow into Polar, down to SKU, marketplace and fulfillment channel. Polar nets the fees out and blends it with Shopify, so you see marketplace profit and channel mix on one P&L instead of a separate Seller Central dashboard.

Seller Central shows Amazon. Your business is more than Amazon.

Seller Central reports Amazon 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 Amazon actually make me, next to everything else,” has no home. Polar is that home.

Amazon on its own

  • Marketplace numbers live in Seller Central, DTC lives elsewhere.
  • Gross sales, with fees buried in separate reports.
  • No blended view of channel mix or true margin.
  • Nothing reconciles against your real P&L.

Amazon with Polar

  • Amazon and DTC on one blended P&L, down to SKU and marketplace.
  • Fees netted out automatically, so margin is real.
  • Channel mix and marketplace profit next to every other channel.
  • Every Amazon dollar reconciled into contribution margin and net profit.

Fees netted, blended automatic

Real margin, not gross.
Polar nets Amazon's fees out and blends the result with Shopify, down to SKU, marketplace and fulfillment channel, so marketplace profit is calculated on real cost.
Note: Amazon syncs at roughly 24-hour freshness (their rate limits), and data comes via Seller Central, marketplace listings alone are not a data source.

One P&L across channels the payoff

DTC and marketplace, together.
Amazon 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 Central dashboard.

The Gap

The connector is only half of it.

Once your Amazon sales, fees and costs 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

Marketplace profit, not marketplace revenue.

Marketplace profit, not marketplace revenue

Amazon looks great in Seller Central until you try to compare it to your DTC store. The numbers are gross, the fees are scattered across separate reports, and there is no way to see marketplace profit next to Shopify on the same basis. Polar pulls gross sales, orders, fees, refunds and costs from Seller Central, nets the fees out, and blends the result into one P&L, down to SKU, marketplace and fulfillment channel. Suddenly the question stops being “how much did Amazon gross” and becomes “what did Amazon actually keep, and how does that compare to DTC.” And with Vendor Central supported too, both sides of your Amazon business land in the same view.

What makes it real

Fees netted out. Amazon's fees and refunds are pulled and subtracted, so marketplace margin is real, not gross.

Down to SKU. Sales and cost resolve to SKU, marketplace and fulfillment channel, blended with DTC.

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