Extensiv in Polar: the costs your store never saw, added to your margin.
Extensiv holds the numbers finance closes on: cost of goods, operating expenses, purchase orders and stock. Your store does not see any of it, so contribution margin is estimated and net profit is a spreadsheet. Bring Extensiv into Polar and margin is computed on what you actually spent.

How to Connect Extensiv to Polar.
A Polar account with Shopify connected, access to your Extensiv instance, and Polar's AI Data Engineer, which builds the connector from a plain-language request.

1
Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Extensiv 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 Extensiv API exposes a field, you can have it, down to a single hidden one the standard connector never pulled.
2
Cost applied to revenue automatic
Real COGS, real opex.
Polar applies Extensiv cost of goods and operating expense to the revenue they belong to, so contribution margin and net profit are computed on ledger cost instead of an average someone typed in.
3
Stock and demand together the payoff
Operations, priced.
Inventory, purchase orders and days of cover sit next to demand and margin, so what you reorder is a profit decision rather than a stock alert.
Side by side
Extensiv closes the books. Polar runs the business on them.
Cost of goods, operating expense and stock live in Extensiv, a month behind and away from the revenue they belong to. So margin is estimated in the store and reconciled later in a spreadsheet. Polar applies the ledger cost to the revenue as it happens.

+Extensiv with Polarblended
Real cost of goods never reaches the store's margin.
Ledger COGS applied per SKU, so margin is real.
Operating expense lives outside the reporting.
Opex applied on top, from revenue down to net profit.
Stock is an operations number, not a profit one.
Days of cover read against demand and margin.
Plan and actuals meet once a month, in a spreadsheet.
Budget against actuals on the same live statement.
The Gap
The connector is only half of it.
Once Extensiv 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.
