I'm selling my inventory SaaS codebase — React 18 + FastAPI + Claude AI — $1000 USD

Hey IH,

I built InventIQ over the past few months — a full inventory management SaaS targeting SMBs in Latin America and Spain. I need to move on to other things, so I'm selling the entire codebase.

Live demo: https://inveniq.vercel.app

Price: $1000 USD (PayPal or Wise)

---

Why did I build this?

Latin America has 25M+ small businesses. Most of them still manage inventory in Excel spreadsheets or paper notebooks. There's almost no affordable, Spanish-language SaaS in this space. I saw the gap and built the product. The market is real — I just can't pursue it right now.

What's the tech stack?

- React 18 + Vite (87 source files, ~600KB source code)

- FastAPI (Python) — 12 routers, async, modular

- PostgreSQL via Supabase — full schema + migrations included

- JWT auth with email verification, password reset, CSRF protection

- Claude API integration — AI-powered inventory analytics

- Docker + docker-compose ready

- Automated tests (pytest) covering auth, multi-tenant isolation, plan limits

---

What does the product actually do?

- Real-time inventory management with barcode scanning (camera-based, no hardware needed)

- Multi-warehouse support with bin/drawer tracking and stock transfers

- Team management with roles + full audit log

- AI analytics: ABC classification, slow-mover detection, demand forecasting, capital analysis

- Invoice generation + PDF export

- Basic accounting module

- Subscription system with 7-day trial + plan limits enforced via backend middleware

- Dark mode, global search (Ctrl+K), onboarding wizard

- Fully responsive (mobile, tablet, desktop)

---

What's included in the sale?

- Full source code (clean ZIP — no credentials, no venv)

- .env.example with all variables documented

- Docker + docker-compose files (dev + production)

- Automated test suite

- README with full setup instructions

- 30-minute handover call on Google Meet

A note on the UI language

The interface is currently in Spanish since it targets LATAM/Spain. All text strings are centralized — translating to English takes 2–3 days. I'm happy to mention this is part of the handover.

Who is this for?

- Developers who want a production-ready SaaS base without building from scratch

- Agencies looking for a white-label inventory system to resell to clients

- Entrepreneurs targeting the Spanish-speaking SMB market

- Freelancers who get inventory system requests and want a ready-made solution
