ChannelBridge Connector Plugin (Headless Middleware)

A lightweight, open-source middleware plugin (installable on any retailer's server or Shopify app store) that acts as a 'translator' between a retailer's primary POS/inventory system and their sales channels. It runs locally or in the cloud, automatically pushes inventory updates from the source system to all channels in real-time, and pulls order data back to the source system. Retailers own the integration; ChannelBridge provides the plumbing and handles version updates, bug fixes, and new channel support.

Value Proposition

One-time setup (no ongoing service fees for basic tier), full transparency into data flows (retailer can audit and modify), no dependency on a third-party service staying in business, and automatic updates as channels change their APIs. Beats SaaS because retailer owns the data and can self-host; beats open-source because ChannelBridge provides commercial support, pre-built channel connectors, and a managed cloud option for those who want it.

Target Audience

Tech-savvy retail store owners, operations managers, and IT teams at mid-market retailers ($2M–$20M revenue) who already have a primary inventory system (Square, Lightspeed, Toast, custom database) and want to control their own integrations without vendor lock-in.

Key Features

  • Pre-built connectors for 8 major channels (Shopify, WooCommerce, Square, Amazon, eBay, Faire, Etsy, custom REST API)
  • Bidirectional sync: pushes inventory from primary system to all channels; pulls orders back automatically
  • Configurable sync intervals (real-time, 5-minute, hourly) based on retailer's needs and API rate limits
  • And more, with full implementation detail...

Tech Stack

Node.js or Python for middleware engine Express.js or FastAPI for HTTP server and webhooks SQLite or PostgreSQL for logging and audit trail Docker and Docker Compose for containerization

Original Problem

Retail businesses struggle to integrate fragmented inventory and sales data across multiple channels in real-time

Retail store owners and managers are losing sales and wasting time manually reconciling inventory across online, in-store, and third-party platforms. Current point-of-sale and inventory systems don't communicate seamlessly, leading to overselling, stockouts, and customer dissatisfaction. They need an API-based solution that automatically syncs inventory data across all sales channels instantly.
