Techo-Bloc: Spécialiste en gestion de commandes

The gap in what exists

Existing enterprise order management systems are often expensive, inflexible, and require extensive customization, leaving a gap for a modern, user-friendly, and more agile solution.

Wedge to win

Target mid-market manufacturers/distributors in the US with a solution that offers faster deployment, lower TCO, and superior UX compared to legacy giants, starting with streamlined integration for common ERPs.

Reputation value (worth doing free for proof) — 50/100

Building a functional, modern order management MVP for a specific manufacturing niche would serve as a strong portfolio piece for enterprise SaaS contracts.

Likely monetization

Seat-based SaaS with usage tiers (e.g., per order volume)

You are an expert full-stack developer. Build a web-based 'Order Management Specialist' SaaS application using Next.js 16 App Router, React 19, Tailwind v4, and Neon Postgres. The core functionality should allow a user to manage orders for a manufacturing and distribution company, similar to the needs described in the Techo-Bloc job posting. Focus on efficient order entry, status tracking, inventory allocation, and basic customer/product data management.

MVP Scope:
1. User authentication (email/password) and a simple dashboard showing pending/completed orders.
2. Create, read, update, delete (CRUD) operations for 'Orders' (with fields like order ID, customer name, product list, quantity, status (e.g., pending, in-progress, fulfilled, cancelled), and date).
3. Basic 'Product' management (product ID, name, description, current stock level).
4. Ability to link products to orders and decrement stock levels upon order fulfillment.
5. Simple filtering and sorting of orders by status, customer, or date.

Database Schema (Neon Postgres):
- `users`: id, email, password_hash
- `products`: id, name, description, sku, current_stock, created_at, updated_at
- `customers`: id, name, email, phone, address, created_at, updated_at
- `orders`: id, customer_id (FK to customers), order_date, status, total_amount, created_at, updated_at
- `order_items`: id, order_id (FK to orders), product_id (FK to products), quantity, unit_price

Frontend:
- Use a clean, responsive UI with Tailwind v4.
- Implement a main dashboard, order list page, order detail page, and product list page.

Backend:
- Use Next.js API routes for all data operations.
- Implement secure authentication using NextAuth.js or similar.

Your task is to provide the directory structure, main component files (pages, API routes), and key code snippets for setting up the database connection, defining models/schemas, implementing CRUD for orders and products, and setting up the basic UI navigation. Prioritize robust error handling and clear code structure. Assume the user will connect to a Neon Postgres instance. Provide setup instructions for environment variables.
