custom connector

Bill.com keeps the books. Polar puts them in the P&L.

Bill.com reports your costs in its own ledger, apart from your Shopify orders, ad spend and margin. So net profit, the number that matters, has to be reconstructed by hand. Polar builds it for you.

Bill.com on its own

  • Costs live in the accounting tool, apart from commerce.
  • Gross revenue, with expenses in separate reports.
  • No blended view of net profit or margin.
  • Nothing reconciles against live performance.

Bill.com with Polar

  • Expenses, COGS and fees ingested and netted.
  • Net revenue and margin on real cost.
  • One P&L, blended with Shopify and ad spend.
  • Profit reflects what you actually spent, everywhere.

Featured Use Case

Net profit, not gross.

Net profit, not gross

Your accounting is accurate but slow and siloed: Bill.com knows the costs, but they live in a ledger disconnected from the Shopify orders, ad spend and margin that make up the operating picture, and net profit only shows up weeks later at close. Polar ingests your vendor bills and operating expenses with a custom connector and resolves them into the same semantic layer as your commerce data, so expenses and COGS net out and net profit is calculated on real cost, in near real time. You stop waiting for month-end to know whether you actually made money.

What makes it real

Costs netted out. Expenses, COGS and fees pulled and subtracted, so margin is real.

Blended everywhere. Once in, accounting behaves like any Polar source across dashboards, reports and AI answers.

Ask Polar, in plain language. “Show net profit and contribution margin on real costs this month.” No SQL, no export.
