Before you upload the sheet back to Square, make sure all the new items are easy to spot.
Add “WA -” at the beginning of the name of every new item and category.
To do this automatically, type this formula in Excel: ="WA - " & C3
This will add “WA -” in front of the item name in cell C3.
You can also use a different label if you like. This step is helpful if you already have old products in the system, so you can easily see which ones are new.
