How does the billing address work for debit cards?

I have been wanting this item for a long time and I am going to use my moms credit card to buy it. If I pay with a debit card, I should not have to pay the bill, it automatically takes it out of her bank account right? If it is paid, and I send the bill to the shipping address would it just be a receipt?|||Yes, it will be a receipt and show what you paid on debit.
