I have run into a unique situation where I would like to expand to other marketplaces but our inventory is not tracked so everything shows up as 0 inventory. I have about 600 products with 30 variations so it makes no sense to do this manually one at a time. Is there a way to change this in bulk or is there an app that will mark the product as having inventory. I'm currently using sellbrite to launch to other marketplaces. Is there something better I could be using that also fixes my inventory problem?
It seems you have a complex situation so the best long-term solution would be to create a Private Shopify App for the custom solutions to connect the inventory. If you need me to set this up feel free to email me at LMPTechSolutions@gmail.com
