I have a deadline approaching and I'm freaking out, help!

How do a define a field or fields for pre-paid accounts. Which will be used like a bank account. I have used the invoice starter solution as a starter for this database.

I have the following tables:

customers

payments

invoicing

products

thanks in advance

Are you asking how to define a field in general, or what table should the field go in, or what your business rules should be to handle payments? This stuff can get pretty complicated.
