How To Have The Credit Card Number Posted On The Invoice Report

Hi all. I was assigned to do this job for a company unfortunately i dont have any experience in zen-cart. now questions:

1. how do i make the credit card number appear on the invoice report?
2. i am confused about the shipping section. the problem of this company is that they dont have a constant shipping rate since it varies on the size of the item they are shipping and the distance. so the best option i think is just to give the the orders, and call the client to finalize the order with the shipping rate.
   are there any other options you think is best?

thanks a lot in advance.

1 you dont put the CC number on the invoice,
you can use the split which will put 1/2 of the cc number there and a second email that has the second parts of the email

2 you can always look for MZMT you can setup multi zones and multi tables,

best bet, just use a good average for the zone
