Extend in Polar: what happens after checkout, priced.
The order does not end at checkout. Returns, claims and protection all move money, and they move it after the revenue has already been booked. Bring Extend into Polar and the post-purchase line lands on the same P&L as the sale, so margin reflects the order that actually stuck.

1
Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Extend 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 Extend API exposes a field, you can have it, down to a single hidden one the standard connector never pulled.
2
Netted against the order automatic
Off the revenue it belongs to.
Polar matches Extend activity back to your Shopify orders and takes returns, refunds and claim cost off the revenue that produced them, rather than as a lump at the end of the month.
3
Read it against margin the payoff
Post-purchase, priced.
Return rate and claim cost sit inside contribution margin and net profit, by product and by market, so the SKUs that come back stop hiding behind the ones that do not.
Side by side
Extend handles the return. Polar prices it.
Returns, claims and resolutions live in Extend, away from the revenue they reverse, so margin is calculated on orders that did not all stick. Polar matches them back to the sale and takes the full cost off, not just the refund.

The Gap
The connector is only half of it.
Once Extend 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.
