I spent months building an invoice & expense management app — then realized other
developers and agencies could skip the 2–3 months of foundation work. So I cleaned it
up and turned it into a template.

What it does

🤖 AI invoice extraction — upload a PDF/photo, it reads merchant, date, amount & VAT
🏦 Bank reconciliation — import CSV/PDF statements, auto-match transactions to invoices
👥 Client & accountant portals — share securely via time-limited magic links
📤 Export hub — one-click Excel / ZIP for your accountant
📊 Projects, proforma invoices, analytics, dark mode

Stack

React 18 · Vite 5 · TypeScript · Tailwind · shadcn/ui · Supabase (Postgres/Auth/Storage/Edge Functions).
npm run build ✅ · 109 tests passing ✅. AI is optional & provider-agnostic — bring a
free Google Gemini key or run without AI.

Would genuinely love feedback — what would make this a no-brainer for your next project?
