What merchants praise

“This app solved a very tricky problem for me—automatic synchronization of the same SKU is truly amazing.”

What merchants complain about

“Could have been a fantastic app, but the quantities are only adjusted when you sell an item. I needed all SKUs to be updated when 1 SKU's level changes (if it is sold or not) When will the next update be, that will fix this issue ?”
