In a past article, we showed you how to add the calculator to the icon bar. But did you know that you can activate the calculator while you are in a Sales Receipt or Invoice?

If we go to a field that asks for a qty or an amount, we can turn on the calculator there by pressing the Equals sign key ( =).

This opens a paper tape.


In this example, we have to add an additional fee to a transaction.


We can setup an Other Charge item for the fee, and leave the amount at 0.00.

When we use the item, and activate the calculator, we will want to enter the percentage as a decimal, since percent signs are not allowed.


We can type in the amount of the item, then use the asterisk key (*) for times, then put in your decimal rate. When you hit the (=) equal sign again, it will put the calculated amount into the field.
