Yep we need negative inventory values too!!! So much so we’ve had to take out store offline until this is resolved or we can find a workaround. All Shopify support can suggest is to upload a CSV file with a negative inventory every time we wish to make a change to a single inventory line item !!
I also don’t understand why we can’t change the committed value when they are not correct.
We use negative inventory values for pre-orders / backorders where we have no physical stock “on hand” but have confirmed availability.
We hear from Shopify that they didn’t think about pre-orders when they made these changes (or presumably drop ship orders, backorders, made-to-order, or non-physical goods sales all of which can create negative inventory values without needing to have a positive amount of “physical goods on hand”). But there still seems to be no intent by Shopify to do anything apart from the usual “raise this with the developers”
Seems all the focus from Shopify now in on making changes for big ticket stores even if it hurts the smaller stores. Since they never even tell us these changes are coming. Awful.
