Shopify gives you multi-location inventory, but it stops at the location level — it has no concept of a bin, a shelf, or a putaway rule. The moment your pick team is hunting for stock or your counts drift, a spreadsheet stops scaling. Lightweight WMS for Shopify closes that gap with a real warehouse structure layered directly onto your existing Shopify locations.

This is a build-to-order app, not an instant App Store install. ECOSIRE designs, builds, installs, and supports it for your specific warehouse layout and SKU profile. We model your bins and shelves as a hierarchy beneath each Shopify Location, store bin assignments in metafields keyed to inventory items, and keep stock truth in sync through the Admin GraphQL API (inventoryAdjustQuantities, inventorySetQuantities) and inventory_levels webhooks. Your Shopify Admin remains the system of record — we never fork your stock count into a shadow database that drifts.

Operators work from a scanner-friendly interface installed as an embedded Polaris app (App Bridge, OAuth-authenticated). Receiving against POs, putaway to bins, barcode-scanned movements, blind and directed cycle counts, and inter-warehouse transfers all flow through guided workflows. Discrepancies are logged with timestamp and user, so a count variance becomes an audit trail, not a mystery.

Because every warehouse is different, scope is set during a discovery call: bin schema, label format, scanner hardware, and which workflows matter to you. You get a clear lead time and a fixed one-time build price — no per-seat SaaS fee compounding as your team grows. You own the installed app.
