No I was not saying that you need to switch the website off for the values to update
I was just concerned that your stock wont be correct on the website if you are updating it via the import at the same time you are have some sales online
i.e. Stock = 50 items online
Then you sell 30 online but you have not packed them yet
At the same time you do an import and make the quantity 50 because you just did a stock take
Then what is the correct stock quanty you want on the website 20 or 50 ?
Anyway sounds like its not a problem if sales online are minimal
