Billing reliability monitoring for subscription SaaS

Stripe can say “paid” while your app gives the wrong access.

BillingGuard CI finds risky Stripe states and monitors them continuously. Add App Probe only when you also want to compare subscription status with the access your application actually grants.

Stripe alone cannot verify entitlement drift.

Pro monitors these Stripe billing states continuously. Add App Probe only if you also want BillingGuard to compare them with the access your product is granting.

Why this exists

Billing failures rarely live in one system.

A subscription changes in Stripe. A webhook fails. A manual override remains active. Your database and billing provider slowly disagree. BillingGuard is built to reconcile those states instead of assuming a successful checkout means everything is healthy.

Free Stripe health scan

Check common risky subscription states before you start a trial. Connect Stripe securely and run the scan in minutes.

Optional Stripe ↔ app reconciliation

Compare what customers pay for with the plan and access state your application actually grants.

Continuous monitoring

Run scheduled audits, keep history and alert only when findings or monitoring state change.

From scan to monitoring

Get value before you commit to setup.

Start with a Stripe-only health scan. If the signal is useful, enable daily Stripe monitoring. Add App Probe later only if you also want BillingGuard to compare billing state with application access.

Run the free audit

01

Run free Stripe audit

Connect Stripe with OAuth and scan subscription health without starting a subscription.

02

Start monitoring trial

If the scan is useful, activate the 14-day Pro trial with no card required to begin.

03

Turn on monitoring

Enable daily Stripe checks. Add App Probe later only if you want deeper access reconciliation.

04

Review changes over time

BillingGuard scores Stripe findings and keeps an audit trail. If App Probe is connected, the same audits also include app-access mismatches.

Built to avoid broad billing access.

Monitored projects connect through Stripe OAuth. BillingGuard's current audit and monitoring implementation performs read operations only, while App Probe is authenticated separately.

Reliability score

A deterministic signal based on detected Stripe billing risks and, when App Probe is connected, billing-versus-access mismatches.

Scheduled checks

Daily monitoring re-runs Stripe audits and records changes instead of relying on manual spot checks. App Probe reconciliation is optional.

Developer-friendly setup

One-click Stripe connection with an optional App Probe contract when you need deeper reconciliation.

Start with a scan, not a sales call.

Connect Stripe, get a health score and decide from the result whether continuous monitoring is worth enabling. Add App Probe later if you need billing-versus-access reconciliation.
