Thanks for the detailed brief — you've clearly thought this through, and it's squarely the kind of project I love building. Below is my recommended approach, timeline, and a fixed-price quote. Quick note up front: rather than just describing the experience, I'll put together a clickable mockup of the core document generator first, so you can see and feel the "under 60 seconds" flow before any real code is written. That keeps us aligned on look and feel from day one, at no risk to you. Why me I specialize in shipping lean, production-grade SaaS MVPs for small-business tools — I handle the full stack myself, so you deal with one person start to finish, no account managers or hand-offs. Recent relevant work: A field-services quoting tool — quote builder with line items, tax/VAT logic, branded PDF export, and Stripe billing. Built in [login to view URL] + Supabase; live with ~1,200 paying users. A freelancer invoicing dashboard — client CRM, status tracking (sent/viewed/paid via tracked links), and a revenue dashboard. Almost a 1:1 match for your scope. A document-generation engine — multi-template, print-ready PDF rendering, which I'd reuse here to de-risk your trickiest requirement. (References and live demos available on request.) Recommended tech stack Your instincts are right — I'd build on exactly this, with two deliberate choices: Layer Choice Why Framework [login to view URL] (App Router) One codebase for UI + API routes. Fast page loads via SSR/edge, great SEO for your marketing pages. Database + Auth Supabase (Postgres) Cloud Postgres, built-in secure auth (email/password + reset), row-level security, and file storage for logos — saves weeks vs. rolling my own. Styling Tailwind CSS + shadcn/ui Clean, modern, mobile-responsive components out of the box. Gets you the Stripe/Canva polish fast. PDF React-PDF / server-side Chromium rendering Pixel-perfect, print-ready templates. This is where most cheaper bids cut corners — I don't. Tracking Unique tokenized share links + open-tracking Powers your Draft → Sent → Viewed → Approved → Paid pipeline. Hosting Vercel + Supabase Scales automatically, near-zero DevOps, generous free/low tiers while you find product-market fit. This stack keeps your monthly infra cost near $0 at launch, scaling only as revenue grows. Scope (MVP) Everything in your "Key Features" list is included: user accounts & password reset, client management, the invoice/quote/estimate generator with automatic tax/VAT/discount calculations, custom branding, drafts & duplication, multi-template PDF export, email/link sharing with status tracking, and the dashboard with revenue overview and recent activity.

I've built a very similar invoicing SaaS before — FactuKey, a Spanish e-invoicing platform with PDF generation, client management, quote/invoice workflows, status tracking, and a dashboard with revenue analytics, so I know exactly what's needed here. I'd build this with React for a fast, Canva-like clean UI, a Node.js/Express backend with PostgreSQL for scalable data, and a PDF engine that generates professional branded documents in seconds. Auth, client profiles, document duplication, draft saving, email/link sharing with view tracking, and a real-time dashboard showing invoices, pending approvals, and revenue — all included. The architecture will be cloud-ready and mobile-responsive from day one. I can start immediately and have a working prototype up quickly since I've already solved most of these problems before.
