Revenue leakage detection is the process of finding where money leaves your funnel before it becomes revenue you can count on. Unlike a one-time audit, detection should be repeatable — you run it when growth stalls, before a big spend decision, or quarterly as a health check.
Signals that leakage is happening
- Traffic or leads up, but revenue flat or down.
- High CAC with unclear payback period.
- Strong top-of-funnel, weak close rate.
- Churn or refunds higher than peers in your niche.
- Invoices paid late or failed card charges you never chase.
If two or more apply, you almost certainly have fixable leaks — not a demand problem.
Detection process (about 30 minutes)
- Draw the funnel. List every step from first touch to repeat purchase. One metric per step, even if estimated.
- Score each stage. Green / yellow / red against benchmarks for your business type. Red stages are leak candidates.
- Quantify impact. Lost conversions × average order value (or ARPU) = monthly leakage estimate.
- Rank by impact × ease. Quick wins on high-impact stages first.
- Assign owners. Each leak needs one person accountable this month.
Tools you already have
You do not need enterprise analytics on day one. Stripe + Google Analytics + your CRM or inbox is enough for a first pass. The gap is usually structure — asking the right questions in the right order. See how to identify profit leaks without a finance team for a lighter-weight version of this process.
Detection vs. prevention
Detection tells you where you are bleeding today. Prevention is building dashboards and playbooks so the same leak cannot reopen — response SLAs, dunning for failed payments, post-purchase email flows. Start with detection; automate prevention after you fix the top leak.
