OLOW Hotel ERP - Final Audit Report
Date: January 27, 2026 Auditor: AI Assistant Status: Complete
1. Executive Summary
This engagement involved a comprehensive code audit, documentation restructure, and quality assurance review of the OLOW Hotel ERP system. The system uses a modern Modular Monolith architecture (Laravel 12 + Livewire 3) with strong Domain-Driven Design principles.
While the foundation is solid, we identified critical risks in Multi-Tenancy Isolation and Financial Data Integrity (Race Conditions) that require immediate attention.
