We are producing new inventory almost daily, and I would like to add units of multiple SKUs to the On Hand inventory in Shopify via csv upload at the end of every production day. Currently, the numbers in the On Hand column of the csv, when uploaded, will overwrite the On Hand number in Shopify. It would be a lot easier for my team to upload the number of new units daily, rather than the number of total units on hand, especially since fulfillment is ongoing. Is there a setting within Shopify, or a ShipStation feature/integration that would make this possible?
Thank you for your reply, I’m glad this is an option. When I downloaded the inventory template, it did not have an “Adjust Inventory” column, so I added one in and put the number 10 in the first row for one product at one location. This did not change the inventory. What am I doing wrong?
