{% hint style="info" %}
Plan determines *what* you can access (and at what granularity). Billing period determines *how far back* you can query.
{% endhint %}

### Step 2: Choose a billing period (controls look back access)

Different billing periods allow different access to historical data.

* **Monthly**: **weekly look back**. Great for clients getting started and focused on current data going forward.
* **Quarterly**: **1-year rolling lookback**. Great for clients who want an extended lookback to validate hypotheses.
* **Yearly**: **3-year rolling lookback**. Option to add even more history, all the way back to **2020**, for full-history research.
