Hello,

I recently changed my eCommmerce platform from BigCommerce to Shopify and I want to change the item ID's to my SKU numbers that I already have linked up in Sage. However, whenever I've done this in a CSV and reimported into Sage the Quantity On Hand has not transferred and shows up as 0. 

Is there any way to change the Item ID like I did and overrite the existing products in Sage so the Quantity on Hand stays the same?

Also is there any way to invoice sales orders in bulk? That would be incredibly helpful as opposed clicking each one individually.
