The formula is basic - Total * 1.03

Above is an image of our dummy invoice - we want to adjust so that it can show total if paying one way (impacting GL as it currently does) and another if paying by CC (Total x 1.03) that does not impact GL at time of invoice

When we invoice, we are set up with the body which subtotals at the bottom, followed by fields for freight costs, sales tax and a total amount. The total amount could be updated to say "if paying by Cash, Check or ACH, Total:" We want to add another field just below this (that does not impact the GL) that shows the TOTAL…

Yes - I would like to do just that without having it be a manual process.
