Stop Paying AI & Cloud Bills for Canceled Users. Win Chargebacks Automatically.
When a customer cancels or their card fails, broken webhooks often let them keep using your app for weeks. RevGuard spots unpaid usage in real time, locks access automatically, and drafts winning Stripe chargeback proof.
- Block "Ghost Usage" Instantly: Cut off unpaid AI token & API consumption while protecting 3-day billing grace periods.
- Win "Friendly Fraud" Disputes: Auto-fill 90 days of verified IP & usage activity into your Stripe Dispute draft without overwriting your notes.
- Audit-Proof EU B2B VAT & Net-30: Verify European VAT IDs via official EU VIES and track wholesale Net-30 deposits on Shopify.
From Silent Revenue Leaks to Automated Protection in 2 Minutes
No complex code changes required. Connect your billing account once and let RevGuard protect your margins 24/7.
Link Stripe, Shopify & App Activity
Install our official app on Stripe or Shopify and connect your existing product events (PostHog, Segment, or simple REST webhook). RevGuard automatically matches every user action to their live billing status.
Spot "Ghost Users" & Chargeback Risks
Instantly see which canceled or overdue accounts are still consuming your expensive AI tokens and cloud APIs—while automatically respecting legitimate billing grace periods and active upgrades.
Auto-Lock Leaks & Win Chargebacks
RevGuard fires an instant signal to pause unpaid accounts (and re-opens them the second they pay). If a customer files a chargeback, we auto-fill 90 days of verified usage proof into your Stripe Dispute draft.
