When setting up terms you have an option to enter a discount percentage. QuickBooks for Mac will allow any number to be entered, but will only work with whole numbers. Any percentages entered as a decimal will be rounded.
For example entering a percentage of 1.5% will result in QuickBooks saving the term with a discount percentage of 1%.
