- Data persistence: Uses local files or a lightweight embedded database in many implementations — no robust database abstraction or migration support; this limits scalability and multi-user use.
- Security shortcomings: Plaintext storage of sensitive data, lack of authentication/authorization, and no input sanitization in places (risk of SQL injection if upgraded to SQL) — not safe for production without hardening.
- Error handling and validation: Missing centralized exception handling and inconsistent form validation (e.g., negative quantities, missing tax settings).
- Testing and maintainability: Little to no unit tests, and some business logic is still inside form event handlers, making automated testing harder.
- Documentation: Readme and inline comments are minimal; setup steps, dependencies, and upgrade notes are often absent.
