Revenue Leakage

Revenue leakage is money you should have collected but didn't. In subscription businesses, the biggest source isn't pricing mistakes or billing errors. It's failed payments. A card expires, a charge gets declined, nobody follows up, and the customer quietly disappears. That's revenue you'd already earned leaking out of your business.

Where SaaS revenue leaks

Failed payments get the most attention because they're the largest single source, but they're not the only one. Downgrades that don't get flagged for a save attempt, free trial conversions that stall because the payment method wasn't validated upfront, and pricing grandfathering that runs longer than intended all contribute. Some businesses also lose revenue to billing configuration errors, like charging monthly rates on annual plans or applying discounts that should have expired.

Put simply, anywhere a manual process sits between you and money owed is a place revenue can leak.

Failed payments as the biggest source

Recurly's data shows SaaS companies see payment failure rates of 5-18%. If your recovery process is weak, most of those failures become involuntary churn. On $200K MRR with a 10% failure rate, that's $20,000 in charges at risk every month. Without dedicated payment recovery, you might save 10-15% of those through your processor's default retries. The rest just leaks.

We've found this is the number that shocks founders most. They'll spend months optimising onboarding to reduce voluntary churn by 2-3%, while 8% of their revenue is quietly draining through failed payments they never investigated.

How to plug the leaks

Start with automated payment recovery. Smart retries, dunning emails, and card updater services together address the largest leak. Beyond payments, audit your billing configuration quarterly. Look for expired discounts still being applied, plans that should have renewed at updated pricing, and trial-to-paid conversion gaps where payment capture fails silently.

Measuring revenue leakage

Track your payment failure rate and recovery rate monthly. The gap between what fails and what you recover is your payment-related leakage. Then look at revenue churn broken down by voluntary versus involuntary. If involuntary churn is above 1-2% of MRR monthly, your recovery stack needs work.
