We would like to setup EFT and Credit Card for client payments.

You have several options, one of which is Quickbooks own payment processing program. https://quickbooks.intuit.com/payments

Hi Elise3,

Thank you for considering Intuit merchant services for your payments needs!  John is correct; Intuit has several options depending on how you want to process payments and what Intuit products you are using (if any).  I would review the site through the link that he posted and see which one will best fit your needs.  On that same site, there is also a direct number to the sales team who can answer any questions you may have.  

You are certainly welcome to ask questions here, as well.  I would be happy to assist!

Thanks!
