How can I add a column to an invoice which shows a quantity which equals one of the columns multplied by a pre-set multiplier?

Hi there, @communityoil.

Currently, QuickBooks only allows you to add a quantity column to an invoice. Adding a column for the result of quantity times pre-set multiplier isn't supported in QuickBooks.

As a workaround, you can look for a third-party application that can add a column for the result of quantity times pre-set multiplier.

To find a third-party application, click on the Apps menu at the left panel, then enter a keyword.
