There are various invoice "Types" . ie we have different templates for the following (and all are customisable):

Standard Invoice - The default invoice template
Standard with EFT - adds the EFT details box
Standard with Credit Card (CC) - adds the Credit Card payment details box
Standard with EFT and CC - add both the EFT and Credit Card boxes (note this does take up a substantial portion at the foot of the invoice)

To change the invoice "Type"

In "Send Invoice"


Select the template you require
and click on close
this setting will stick for next time,  but only on the workstation you are working on
