Subscription billing reconciliation and monitoring service for SaaS companies

Published Feb 18, 2026

🔴 Problem Identified

SaaS companies using Stripe or other payment gateways often have billing mismatches where payment status doesn't align with user access permissions. Common issues include failed renewals going unnoticed, delayed webhooks, payments not updating access properly, and refunds not syncing correctly. Many early-stage startups only discover these problems when customers complain.

💡 Proposed Solution

A monitoring service that continuously compares payment provider state with actual user entitlements in the app, providing real-time alerts for mismatches, automated reconciliation reports, and dashboards showing billing health metrics. The service would integrate with popular payment gateways and common SaaS platforms to provide read-only monitoring and alerting.
