Inventory Sync

Store Design

Topic summary

Connecting Shopify inventory to Amazon/eBay so purchases there automatically reduce Shopify stock and Shopify acts as the single source of truth.

Core approach: use marketplace integration apps that both manage listings and import marketplace orders into Shopify. When orders are pushed into Shopify, the associated product quantity is decremented; updates made in Shopify then sync back to marketplaces.

Recommended tools mentioned:

  • Shopify Marketplace Connect (by Codisto): supports Amazon, eBay, Walmart, Etsy; uses Shopify inventory as primary and keeps counts synchronized.
  • LitCommerce: syncs Amazon/eBay orders to its dashboard; supports Shopify; reported smooth operation with paid plans.
  • CedCommerce eBay Integration; Salestio (free plan available, additional charges may apply).
  • Nembol: imports Amazon/eBay orders with a paid upgrade; limited automation for shipping labels.
  • MapMyChannel by WebBee; other alternatives cited include ChannelGrabber and Orderlytics.

Alternative for low volume: manual CSV order import into Shopify (free but not seamless).

Key considerations: free, fully unlimited options are rare; choose based on required automation (order import, label/fulfillment flows). Set Shopify as the main store during setup for consistent stock control.

Status: no final selection by the requester; multiple viable app-based solutions presented; discussion remains open.

I’m selling on both Amazon and Ebay while having LitCommerce sync orders for me, and it is running smoothly I guess. This feature is sort of easy to use and convenient; it syncs all my orders from both Amazon and Ebay to my LitCommerce dashboard and I will manage all my order information there. I used to route all orders to my Ebay store as well after the orders arrived at my LitCommerce dashboard, but these days I only stop at the dashboard.

I remember they do support Shopify and Wix too. Just pick Shopify as your main store and Amazon and Ebay as a sales channel during the setup.

I have just upgraded my pricing plan and I think their services don’t cost too much compared to other tools. Just chat with them and see if they have a suitable plan for you.
