Flexport in Polar: what it costs to get the order there.
Flexport runs the shipping. What it does not do is put the cost back on the order, so freight stays an operations number while margin is calculated without it. Bring labels, carriers and delivery performance into Polar and shipping cost lands inside contribution margin, by SKU, by market and by method.

1
Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Flexport in plain language. It reads the source documentation, lays out everything the API offers by category, then writes the connector and pipes the data into your warehouse as governed data. No code, and it ships in minutes.
Worth knowing: this also works on connectors you already have. If the Flexport API exposes a field, you can have it, down to a single hidden one the standard connector never pulled.
2
Cost on the order automatic
Freight, applied where it was spent.
Polar matches shipments to your Shopify orders and applies the label and handling cost to the order, so contribution margin is calculated after freight instead of before it, down to SKU, market and method.
3
Read it against margin the payoff
Operations, priced.
Shipping sits with cost of goods, payment fees and ad spend in contribution margin and net profit, so the expensive routes and the expensive products are visible instead of averaged away.
Side by side
Flexport runs the warehouse. Polar prices what it costs you.
Fulfilment and shipping detail live in Flexport, away from the revenue they support, so shipping stays an operations number instead of a margin one. Polar puts the cost back on the order.

Shipping and fulfilment cost sit apart from revenue.
Cost applied to the order, so margin is net of shipping.
No view of which products or markets are expensive to ship.
Cost by SKU, market and method, against contribution margin.
Operations metrics with no financial read.
Fulfilment read against net profit, not just throughput.
Reconciling with your store means a manual export.

The Gap
The connector is only half of it.
Once Flexport is modelled against your real orders 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.
