Unified Ecommerce Dashboard for all ecommerce channel link via API

I’m building a, web application that lets me see and control all of my Amazon, Flipkart and Meesho seller accounts from one place. The stack is already decided—Python 3, Flask and SQLite—so you’ll be working end-to-end on something that can run easily on a small VPS.

Core features I need right now
• Seamless API integration with Amazon, Flipkart and Meesho (order and inventory endpoints only).
• A clean dashboard that shows new orders in real time and lets me update their status, print packing slips and push fulfilment details back to each marketplace.
• Inventory tracking that keeps the local SQLite stock levels in sync with each marketplace and flags low-stock SKUs.

There’s no user authentication layer to worry about; the site will sit behind my own server-level restriction. Good modular code, clear comments and a short README are important so I can extend the project later.

Deliverables
1. Flask project with blueprints/modules for each marketplace, ready to deploy with gunicorn.
2. SQLite schema and migration script covering products, orders and marketplace credentials.
3. Responsive HTML/CSS (Bootstrap or similar is fine) for the dashboard views.
4. A simple settings page where I can paste marketplace API keys.
5. README with setup steps, API rate-limit notes and examples of how to add another marketplace.

Acceptance criteria
• Successful GET/POST round-trip for orders and inventory on all three marketplaces using sandbox or test credentials.
• Dashboard updates without page refresh (axios/fetch preferred).
• PEP8-compliant codebase that runs with `python -m unittest discover` showing zero failed tests.

If this sounds straightforward for you and you’ve built marketplace connectors before, let’s talk and get this dashboard live.
