How it works
—
What it does
Sumtracker keeps stock levels in sync across Etsy, Shopify, eBay and Amazon even when each channel uses different SKUs or titles - map listings once and every sale automatically adjusts inventory everywhere. Bundles, location-based stock and purchase orders are supported, with a free tier for small catalogues that Shopify forum threads repeatedly recommend.
Platform compatibility
Where it actually works, and what it does badly. Updated when vendors ship changes, not when we find time.
