I recently built a full-stack inventory management system as an internal tool and learning project, and it turned into something more complete than I expected.
The system includes:
- Authentication (JWT + Google OAuth)
- Multi-organization support
- Inventory & stock tracking
- Orders & customer management
- Analytics dashboard
- Image uploads (Cloudinary)
- Modern admin UI built with React + Vite + Express
Some things I learned along the way:
- Internal tools grow faster than expected once multiple users are involved
- Role-based access becomes necessary very early
- Analytics are usually an afterthought, but stakeholders ask for them first
- Treating internal tools like products saves a lot of refactoring later
I’m not turning this into a SaaS — it’s a complete codebase intended for developers or small teams who want a ready internal tool instead of building from scratch.
For anyone interested, I’ve shared demo videos and the full codebase here:

If you’re a founder or developer who’s built internal tools before, I’d love to hear:
– Would you build this yourself or buy a ready codebase?
– What features usually matter first for internal dashboards?
Happy to answer questions.
