Hi @kschen ,
You can check out hubbed.co's shopify app here. We have a shopify app that helps you sync your shopify inventory with Lazada and Shopee so you don't have to manually update the inventory daily anymore 😄
What's even better, you can fulfil all your orders from Shopify, Lazada, Shopee all in one system.
Pick and pack and ship it out all centrally! Hubbed helps update the status on Shopify, Lazada and Shopee so you don't have to keep going into different seller centres.
There are also other features like Wave Picking, bundling, warehouse inventory management, and inventory reports to help you make better inventory decisions.
Hope this helps! 🙂 will be happy to walk you through the features as it is a pretty packed app.
