I currently use Quickbooks pro 2002 with a Chase merchant account. It works great so far. I love the integration to quickbooks. I also signed up with their optional email service, that allows you to email statement directly from quickbooks, keep track of them online, and allows clients to view their balacne and invoices online. The $4.00 monthly statement is not optional, putting Chase and Wells Fargo at the same price.
Keep in mind that if you choose to accept American Express, that because you are an internet business, they have a $5.00 monthly fee also. Let me know if you have any more questions about their service.
There is no link to the public that I can tell. You need to be in Quickbooks 2002 and you signup through there. This is an offering through Intuit that is fully integrated to Quickbooks. You won't get a vitual terminal, or anything like that. You process everything through quickbooks.
