I’m putting together a fresh Laravel module that will calculate budgets end-to-end and I want it coded cleanly, following Laravel best practices so it drops straight into an existing 10.x project. The core is a single page where users can input figures, hit “calculate,” and immediately see totals as well as any over- or under-spend. I’ll handle styling later, so you can focus on controllers, models, validation and a crisp Vue or Blade-AJAX front end for live feedback. Here’s what I need from you: • A migration and eloquent model for storing each budget entry. • A controller and service layer that performs the calculations and returns JSON. • A simple Blade (or Inertia) view that consumes the JSON and renders the results dynamically. • Tests proving the math is solid and edge cases are covered. Ship the code in a pull request with concise setup notes and I’ll take it from there.
