I see that SKU is a field that can be used in an activity table when designing sales forms. However, I can't see how to access it or enter data into it?

Hello Haydenkendler, Thanks for your question about showing SKU on the invoice. TO do this if you go to the settings cog in the top right of Quickbooks and then go to account and settings>sales>products and serices>show item service code column and then toggle that on. Then save the changes in that section. Exit out and you should now see the SKU column to be able to use.
