PostHog Custom Events: How I Tracked a $59 Payment Funnel from Page View to Stripe Checkout

Short summary

Track exactly where users abandon your SaaS payment funnel using PostHog custom events. Create five focused events (page load, CTA scroll, demo click, checkout start, purchase), implement them with reusable React components in Next.js App Router, then visualize drop-off rates in PostHog's funnel view to pinpoint whether the problem is your copy, your design, or your checkout flow. The key: keep event noise low, fire events from component lifecycle, and use the data to stop debugging wrong things.

• •Map funnel steps before writing code, keep event count low (5 events for this flow) to avoid noise
• •Implement events with reusable React components (page view, button clicks, intersection observer for scroll visibility)
• •Use PostHog's funnel view to identify exact drop-off point and determine root cause (copy, design, or flow)
