Can multiple Shopify websites share one inventory?

Topic summary

Sharing one inventory across multiple Shopify storefronts (different domains/designs) is possible via third‑party apps; Shopify Support recommended Syncio Multi Store Sync, Multi-Store Sync Power, and InventorySync, and advised contacting each developer for specifics.

Trunk was highlighted for real-time syncing across multiple Shopify stores, building a centralized inventory and updating stock on sales or manual changes. It requires matching SKUs (stock-keeping units) across stores and supports bundles/kits; a corrected help link was provided.

A merchant asked about creating a single B2B/wholesale site aggregating products from four B2C Shopify stores (plus extras) and whether a new site is needed. Support redirected to app developers; no clear solution was confirmed, and a follow-up indicated it remains unresolved.

Cost concerns were raised for smaller stores, while others endorsed Trunk. Additional options promoted: Sync Master Gogo (pay-as-you-grow pricing, multi-location and multi-store syncing, SKU-based or manual product grouping) and Crab Sync.

Outstanding question: whether these apps can prevent overselling with simultaneous orders across stores. This was not answered, and the thread remains open with no final decision.

Very interesting but these apps are hugely overpriced for smaller stores with smaller inventory. I mean starting at $35 for 0-100 order? It’s over the top. Plans should start from $5 per month. Just saying…
