RevClamp Enterprise B2B REVENUE ASSURANCE Start Free
AUTOMATED UNPAID USAGE, CHARGEBACK & EU VAT PROTECTION
Built for Stripe SaaS & Shopify B2B Merchants

Stop Paying AI & Cloud Bills for Canceled Users. Win Chargebacks Automatically.

  • 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.

HOW IT WORKS IN 3 SIMPLE STEPS

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.

STEP 1 • CONNECT

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.

Zero checkout slowdown • 100% EU privacy safe
STEP 2 • DETECT

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.

Zero false lockouts on paying customers
STEP 3 • RECOVER

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.

$1.42 per unpaid AI call caught = $4.26 saved in a single session • Keep 100% of recovered revenue
