Stock that stays true across Shopify, Square, and everything else.
InventoryLink is a bidirectional sync engine for omnichannel merchants. Shopify and Square work out of the box — any other ERP, warehouse system, or POS connects through our public API. Every sale, return, and adjustment propagates in milliseconds, with loop protection built in.
