Signup-to-paid funnel tracking

A signup-to-paid funnel shows where visitors become customers and where money leaks out.

The common mistake is stopping the funnel at signup. Signups matter, but SaaS revenue comes from paid conversion, renewals, expansion, and retention. A source that creates many free accounts but no paid customers is not performing the same as a source that creates fewer signups and more MRR.

A practical funnel

Start with a short funnel:

1. Landing page visit.
2. Signup started.
3. Account created.
4. Activation event completed.
5. Checkout started.
6. Subscription started or purchase completed.
7. First renewal.

You can add trial started, invite sent, project created, or integration connected when those actions predict paid conversion.

Choose stable events

Good funnel events are durable. They should survive UI redesigns and product copy changes.

Prefer:

• signup_started
• account_created
• project_created
• trial_started
• checkout_started
• subscription_started
• renewal

Avoid events that describe small button clicks unless they are truly meaningful. Too many steps make the funnel noisy.

Segment by acquisition context

The funnel becomes more useful when segmented by:

• Source.
• Campaign.
• Landing page.
• Referrer.
• Device.
• Country.
• First-touch vs last-touch model.

This shows whether the problem is acquisition quality or product conversion. If one campaign gets many signups but few paid accounts, the campaign might be overpromising. If every source drops at checkout, the checkout path may be the issue.

Include revenue quality

Paid conversion rate is not enough. Add:

• MRR by source.
• Revenue per signup.
• Refund rate.
• Renewal rate.
• Churn by source.

This prevents the team from optimizing for cheap signups that do not retain.

Use the funnel for decisions

The best funnel review ends with a concrete action:

• Rewrite a landing page.
• Improve onboarding before trial.
• Fix checkout friction.
• Stop a campaign that produces refunds.
• Double down on a source with high renewal quality.

The report should help decide where to spend engineering, content, and marketing time.
