Please advise if this is compatiable with Quickbooks and also we do not need to set up a merchant acct. Can we use our own.
Sorry. This system is not compatible with Quickbooks.
You can use your own merchant account as a separate system if you desire however it will not be integrated with our electronic payment system. If you have a merchant account on the NMI, USA EPAY or AUTHORIZE.NET gateway we do have an add on product called payment runner that can process your credit / debit cards regardless of which merchant account you have.
