Stock Management

Hi All

I have stock management set up, which works with all of my previous products that have been on my site for years. However anything new i upload, as soon as a size is purchased on any of my new variable products it puts that size out of stock and into -1. Its almost like any of my new products dont talk to the products on my till even though the plu numbers that are meant to be recongnised between the till and website are correct.

Any guideance would be super helpful. I’m starting to miss sales because of it!

Many thanks

Jon
