I sell on Shopify, Etsy and Amazon with different SKUs and titles. I need proper inventory sync so selling on one channel updates the other immediately.

Any suggestion of any tool that can help me with this?

Hey @Raynee

You could try SellBrite, CedCommerce, or Linnworks, they all sync inventory in real time across Shopify, Etsy, and Amazon so a sale on one updates the others instantly.

For syncing Shopify, Etsy, and Amazon (even with different SKUs/titles), tools like SellBrite, CedCommerce, or LitCommerce can handle real-time inventory updates and SKU mapping.

If you’d like, I can help set this up so stock updates instantly across all your channels without manual work. You can reach me via my portfolio here: https://www.rajatweb.dev.

You can try Sumtracker, it solves the headache of managing inventory of multiple channels.

It updates stock in real time across all channels, even if you have different SKUs or titles on each platform. You just map them once in Sumtracker, and any sale automatically adjusts inventory everywhere.

You can give this blog a read as your use case has been clearly explained in it.

@Moeed I have used CedCommerce and I faced issues while uploading products. I had to put in the same info again and again that wasted a lot of my time. As for Linnworks and sellbrite they don’t have that great of ratings on app store so kind of skeptical to try.

Never heard of sumtracker, will research more about it before trying.

Update: I’m on day 6 of my free trial with sumtracker, and hands down it’s the best inventory management software I’ve used so far. It completely solved my problem of syncing inventory across channels.. @Bhoomisingh29 Thank you so much for the recommendation
