Shopify WMS integration cost
Per-store connector fees, per-order ingest fees, and multi-store Shopify Plus uplift. Logiwa, ShipHero, and Extensiv ship native Shopify connectors. Best-of-breed and ERP-native WMS route via middleware.
Native vs middleware
Logiwa, ShipHero, and Extensiv ship native Shopify connectors bundled into the platform fee.[s-32][s-33] Best-of-breed (Manhattan, Blue Yonder) typically route via Celigo, Boomi, or a vendor partner. Middleware is billed per connection; as a rough planning estimate, budget on the order of $300-$1,500/mo per flow.
Shopify Plus and multi-store
Multi-store Shopify Plus adds per-store connector configuration. Expect 4-12 additional SI hours per store. Inventory-sync interval (real-time vs every-15-min) is the chief failure-mode setting; scope it into the contract.
TikTok Shop and other channels
Logiwa and ShipHero have shipped TikTok Shop connectors in 2025-26. Manhattan, Blue Yonder, and SAP EWM rely on middleware. Per-channel connector fees are usually included in the WMS platform fee on the SMB stack.

Inventory-sync failures - what happens?
Inventory drift, oversells, and stockouts. The contract should specify sync interval, retry logic, and what happens when Shopify is rate-limiting.
Per-store connector fee?
Bundled into the platform fee on the SMB stack. $25-$50/mo per store on middleware deployments.
