Now, supposing you have chosen your credit card processor and been accepted for a merchant account (if this is what are going to do initially) - then the next major  step  is  to  find  a  shopping  cart  that  will  work  with  that  credit  card processor - most do, but before you choose, check it out! Nothing worse than spending days building your webshop to find it won't work with the credit card processor you have chosen. We have some partners we work with and some of these come with no up-front costs - always a boon to anyone setting up a mail order business. See the section on shopping carts for more on this.
