# Connecting your data to Bigdelta

Bigdelta works best when it can see **both revenue truth and early behavior change**.

## Step 1: Connect Billing Data (Required)

Billing is the foundation for trust.

Bigdelta connects read-only to systems like:

* Stripe
* PayPal
* Shopify Partners
* PayMe

Billing data ensures:

* Accurate revenue numbers
* Board-ready confidence

Bigdelta never modifies billing data.

## Step 2: Connect Product Data (Recommended)

Billing shows *what happened*.\
Product data shows *what’s about to happen*.

Product data allows Bigdelta to:

* Detect activity trends
* Identify churn and expansion Signals earlier
* Rank accounts by urgency

Bigdelta uses following product data:

* Product tracking (events, pageviews)

{% hint style="info" %}

#### Tracking script <a href="#h_05071dd1ca" id="h_05071dd1ca"></a>

The first step to start sending data to Bigdelta is putting our tracking script on your website and/or product. It should take no longer that 10 minutes to get up and running. You can get detailed instructions how to setup tracking script in [developer documentation](https://docs.metrical.io/start_here).

* Product usage (entitlements, limits and usage)
* Feature adoption (based on product tracking events)

Product data is:

* Read-only
* Aggregated into activities, entitlements and feature adoption
* Used to detect trends, not inspect raw events

## Step 3: Add Feedback (Optional)

Product data shows *what’s about to happen*. Feedback explains why.

Feedback data allows Bigdelta to:

* Identify churn and expansion signals earlier
* Rank accounts by urgency

Bigdelta supports following feedback data:

* Feature Requests
