• Form-level & menu-level security — Granular permission control down to individual form actions (Insert / Update / Delete), not just page visibility.
• Login audit trail — Every login event is recorded, giving administrators full visibility of system access history.

• SMS & email gateway integration — Configurable SMTP and SMS REST API for automated payment reminders, alerts, and customer communications built into the system.
• AI-agent ready codebase — Clean ASP.NET C# page-per-feature structure works seamlessly with Claude Code, Cursor, Gemini, and GitHub Copilot for rapid customization.
