My company needs a straightforward invoicing application that we can either host in a browser or install on office desktops—whichever you feel is the leanest route. Core requirements are simple but non-negotiable: every invoice must calculate taxes automatically according to rates I configure, and the system has to keep a searchable customer database so future bills pull the right details instantly. All invoices will be produced manually from an on-screen form; there is no need to connect to live sales data or set up scheduled runs. If you choose a web stack, I’m happy with a standard LAMP/MEAN approach or something in Django, Laravel, or ASP.NET—use whatever lets you deliver a clean UI and reliable performance. If you prefer a desktop build, a lightweight Electron, .NET, or Java solution is fine. Cross-platform is a bonus but not essential. Deliverables • Running application (web or desktop) ready for production use • Source code with concise inline comments • Brief setup guide and user manual (PDF or markdown) I’m after practicality and maintainability over fancy extras, so keep the architecture clear and the codebase easy to hand over. Looking forward to seeing how you would tackle it.
