It is possible to add a surcharge for Credit Card payment to an invoice as a % calculation of the invoice total. This is then shown as an additional line in the invoice totals.
On clicking Edit for an individual invoice, an Options box appears at the bottom of the page with [Apply CC Surcharge]. Select the [Apply CC Surcharge] checkbox and enter the numeric % charge to be applied and clicking [Save].
The CC Surcharge is automatically calculated and added as an additional line within the invoice total.
