# Cost & revenue tracking

> Once your app is instrumented with the SDK, every AI call streams to your dashboard.

Instrument your app with the [SDK](/quickstart), and Weflayr turns that stream of calls into three pages:

<Columns cols={2}>
  <Card title="Overview" icon="gauge" href="/product/overview">
    Your daily AI spend and usage.
  </Card>

  <Card title="Cost" icon="coins" href="/product/cost">
    What each feature costs.
  </Card>

  <Card title="Margin" icon="scale-balanced" href="/product/margin">
    Profit and loss per customer.
  </Card>
</Columns>

Revenue and metadata come from the [Configure Cost & revenue](/configure/introduction) pages: [sync your revenue](/configure/sync-revenue), [tag your customers](/configure/customer-tags) and [declare free AI credits](/configure/free-ai-credits).

Tracking an internal AI tool/process with no revenue? Use an [internal project](/internal-projects) instead.
