There needs to be a credit card field that gets inserted into an invoice that clients can fill out where we have Name on card, address of card, card #, expiration date, cvs code which also pulls the invoice number and balance due in to the same area. If you do internet or phone sales you have to have a copy of the creidt card info with the clients signature to protect your self from fraudulent charge backs. This items always have to be one the same page. So when the page is broken up into two printed pages the credit card and signature section has to stay together and it must reference the invoice number and balance due.
