Luhuss/Sistema-Contable-PHP ? reverse-engineered prompt

Build me a simple accounting system in PHP for a small business.

I want a clean web app where I can log in, manage users, and keep track of basic money movement like income, expenses, and maybe invoices or sales records. It should let me add, edit, and delete entries, see totals at a glance, and generate a few useful reports so I can understand how the business is doing. Please make the interface easy to use and organized, with a clear dashboard and forms that don’t feel complicated.

Set it up in a way that is easy to run locally, with the database structure included, and keep the code separated so it is maintainable. If anything is unclear, use sensible defaults and look up current best practices online if needed. I’d like the project to feel like a solid starter accounting system that can be expanded later.
