Revenue Linter

Find SaaS billing and access mistakes before customers do.

RevLint reviews billing state, app access, lifecycle events, webhook coverage, refunds, disputes, and evidence gaps so founders can see where revenue or access has drifted, and where proof is missing, before it becomes support cleanup.

Who this is for

SaaS founders with subscriptions, trials, cancellations, failed payments, refunds, or manual admin access.

Especially useful after pricing changes, billing migrations, customer portal launches, custom entitlement work, or any period where failed payments were handled manually.

What Revenue Linter checks

Review billing, access, lifecycle, and evidence drift without production writes.

  • Access mistakesPaying customers who may be locked out or on the wrong plan.
  • Lifecycle and webhook gapsFailed payments, cancellations, refunds, and disputes that may not reach the app.
  • Evidence readinessTerms, login, usage, cancellation, refund, dispute, and support evidence gaps.
  • Revenue reconciliationStripe, PayPal, order data, refunds, metadata, currency, and amounts.
  • Engineering handoffPlain-language findings, estimated exposure, recommended next step, and fix-path context.
Stripe is the billing side, not the whole access story.

Stripe changes are disabled in Revenue Linter. Stripe shows billing state. App/access evidence confirms whether customers actually have the right product access.
