> Aquarel stops active recurring-revenue leaks across custom SaaS billing systems, Stripe integrations, and WordPress/MemberPress/WooCommerce membership portals. Backed by hands-on production rescue pedigree at MemberFix, Principal Engineer Dositej Grbović fixes broken webhook handlers, subscription state drift, checkout failures, and authentication lockouts in rapid Rescue Sprints starting at $1,000–$1,500.

## Symptom-to-Fix Diagnostic Matrix

| What You Experience (Founder Symptom) | Root Technical Cause | Aquarel's Surgical Engineering Fix |
| --- | --- | --- |
| Customers complete Stripe Checkout, but their membership tier or SaaS account stays locked | Missing or failing webhook signature verification, unhandled checkout.session.completed races, or timeout errors. | Implement signature-verified, idempotent webhook processing with dead-letter retry safety and state reconciliation. |
| Cancelled or past-due subscribers retain free access while active paying members get locked out | Desynchronized local database status fields vs. canonical Stripe customer.subscription.updated/deleted events. | Build deterministic subscription state machines and run automated Stripe-to-database entitlement reconciliation. |
| Membership login loops, caching conflicts, or plugin updates break checkout during a live campaign | Aggressive CDN/page caching on authenticated routes, conflicting payment scripts, and unguarded live updates. | Isolate authenticated cache-control headers, decouple conflicting hooks, and enforce staging-first checkout tests. |
| Duplicate subscription charges or double-provisioned accounts when Stripe retries slow webhooks | Webhook endpoints lacking database event-ID idempotency locks and transactional row updates. | Introduce an atomic stripe_events idempotency table and wrap entitlement mutations in strict database transactions. |

## Phase 1: Free 48-Hour Initial Codebase Audit Checklist ($0)

1. End-to-end Stripe webhook event log, signature verification, and idempotency key audit
2. Database entitlement vs. active Stripe subscription state reconciliation diagnostic
3. Checkout funnel, renewal lifecycle, and authentication session/cache header inspection
4. 10–15 minute plain-English Loom walkthrough + prioritized Red/Yellow/Green revenue-protection plan

## Phase 2: Fixed-Scope Rescue Sprint & Vibe-Safe Handover Deliverables

1. Idempotent, signature-verified Stripe webhook pipeline handling upgrades, renewals, and cancellations
2. Reconciled subscriber database records eliminating ghost access and false lockouts
3. Hardened authentication, password/magic-link recovery, and cache-bypass rules for member areas
4. Automated billing health checks + Vibe-Safe Handover documentation and Loom walkthrough

## Technical Architecture & Rescue Approach

## Stop Silent MRR Bleed From Broken Webhooks & Auth Lockouts

Nothing erodes founder trust faster than a paying customer who cannot log in—or silent webhook failures that leak thousands in monthly recurring revenue. With hands-on rescue experience at **MemberFix** (`memberfix.rocks`) and deep full-stack Stripe architecture expertise, I make your billing and entitlement pipeline rock-solid.

### Deterministic Subscription State Machines Across Custom SaaS & Membership Portals

AI-generated billing code and brittle membership plugins routinely rely on client-side redirect URLs instead of verified server-to-server webhooks. I replace fragile checkout callbacks with cryptographic signature verification, database-enforced event idempotency, and automated state reconciliation.

## Frequently Asked Questions

### Our checkout or membership login is broken right now—how fast can you step in?

Select 'Production Emergency' on the /triage page to trigger our 24–48 Hour Emergency Stabilization Fast-Track (starting at $1,500). It dispatches an immediate mobile alert to Dositej with a 2–4 business hour response commitment.

### Do you rescue both custom Next.js/Supabase Stripe apps and WordPress/MemberPress sites?

Yes. Having rescued production membership sites at MemberFix alongside custom React/Next.js/Supabase SaaS platforms, I diagnose and fix billing pipelines across both modern TypeScript stacks and WordPress/MemberPress/WooCommerce portals.

### How do you fix Stripe webhook desynchronization without double-charging customers?

All webhook fixes are built around strict event-ID idempotency tables and read-only reconciliation scripts before applying state updates in staging and production.

### What does the initial 48-hour billing & codebase audit cost?

The initial 48-hour Codebase Audit is $0 and zero obligation after our 20-minute Triage Call and mutual NDA.

### Can you audit historical Stripe events to find out how many subscribers were affected by a webhook bug?

Yes. During the Rescue Sprint I run a read-only reconciliation diff between your canonical Stripe customer/subscription records and your application database so every affected member account is accurately restored.
