Build me a simple but polished web app for small businesses to manage accounting and inventory in one place.

I want users to be able to track invoices, bills, expenses, payments, and stock, and have everything flow into proper double entry accounting behind the scenes. The app should give a clean dashboard with financial summaries and useful reports so someone can quickly see profit, cash flow, and what is owed. Please make it feel like a real product, with a straightforward setup for self hosting and a smooth experience for everyday bookkeeping tasks.

If you need to look up current docs online while building, go ahead. Focus on making the core workflows understandable for non accountants, and keep the interface modern, simple, and trustworthy.
