Omnichannel Inventory Sync for Shopify + Etsy
The Opportunity
A Shopify app that keeps inventory counts synchronized across Shopify, Etsy, and other connected sales channels in near real time. It helps merchants avoid overselling, stock mismatches, and manual end-of-day updates.
"Merchants selling the same physical products on multiple marketplaces are struggling with inventory chaos, double-selling, and manual reconciliation."
