Because you're going to have a 1-1 relationship between invoice and invoice customer info, and because every invoice will have customer info, I would just put it in the invoice table.

> Should the customer info. actually be stored in the same table as the other invoice info, or should I create another table with this info. and a link to it from the invoice table? Ultimately, the end result is the same, but I'm sure one is considered technically correct.
