Thank you for your feedback. We've had several requests to add UPC to the import/export CSV file. Due to this we plan to add support for this field via our CSV upload process in the coming weeks. We don't yet have a set release date for this feature but I will update this thread again as more information becomes available.
As for assigning suppliers to products I have a few follow up questions as this is also a process we plan to update before the end of Q1.
Michael, in order to assign suppliers to your products would it be easier if you were able to select products in the product catalog and then click a button to "assign supplier" where you could select from your saved list of suppliers? Or is your preference to have the supplier name, supplier SKU etc added to the CSV upload process?
