A complete integration covering every layer of unified commerce — inventory, orders, products, customers, and returns.
Real-time inventory sync
Inventory updates across Lightspeed and Shopify automatically. Safety stock thresholds prevent overselling while keeping in-store stock available.
Order routing and fulfillment
Shopify orders are automatically routed to the right store or warehouse based on priority, proximity, or tags. Supports ship-from-store, BOPIS, and local delivery.
Product publishing
Publish products from Lightspeed X-Series to Shopify including descriptions, images, weights, pricing, and sale prices. Control attribute updates.
Multi-location and multi-site
Connect multiple physical stores and multiple Shopify sites. Each location manages its own inventory and fulfillment. Each site has it's own catalog.
Returns, exchanges, & order edits
Process refunds, exchanges, and order edits across channels — a capability no other integration offers. Compatible with Loop Returns, Narvar, Returnly, and Shopify returns.
Gift card integration
Customers can buy, receive, and redeem gift cards at any location or online. Balances sync across platforms in real time.
