Hi everyone,
I am currently building a custom billing and invoicing software for our web development agency (https://nextgenkerala.in/). I decided to build this using core PHP, HTML, CSS, JavaScript, and MySQL to keep the application lightweight and fast without relying on heavy frameworks.
Could experienced backend developers suggest the best design patterns or security practices for handling financial records securely in pure PHP? I want to ensure the database architecture is scalable as we onboard more clients.
Any advice is appreciated!
