Middleware that bridges any POS to any e-commerce—fix discrepancies automatically.
Small retail business owners are frustrated with expensive and unreliable POS systems that fail to integrate with e-commerce platforms, causing constant inventory discrepancies and lost sales.
StockBridge connects existing POS systems (Square, Clover) to e-com platforms via simple API keys, syncing inventory bi-directionally every minute. It detects and auto-resolves common discrepancies like oversells. No need to replace your POS hardware.
