Why is this crucial?

In SaaS, free trials are the top of your funnel—but only paid users drive revenue. Tracking the ratio between them defines the health of your growth engine.

What’s the blocker?

• GA4 logs trial events, but not billing
• Payments live in CRM or Stripe
• Without merging, you can’t see the full funnel

How can BigQuery help?

By joining product events with billing data, you can:

• Identify trial users
• Check whether they made a payment
• Measure the true trial-to-paid conversion rate

What’s the result?

A clear SaaS growth metric that investors, founders, and product teams can rally around.
