Authorize.net Gateway with Quickbooks

I've been sitting on this to maybe get back to it. I've considerable experience with all of this ... but I can't quite make out what you are actually looking for here.

Are you asking if it's possible to use Inuit's merchant services (merchant account) along with Authorize.Net's payment gateway (which would be connected with the Intuit merchant account)?

To the best of my knowledge, that's not an option with Intuit, but if it is possibly an option they can provide, you should contact them (and please share here what you find out). It's really more of an Intuit merchant services issue than anything else -- namely, can this or that 3rd party gateway/virtual terminal be plugged into the payment processing network they have.

I would expect that you would be looking for such a solution because you currently process payments through QuickBooks, but also want use the same merchant account processing through a payment gateway on your online store, else I'm not sure why you'd prefer Intuit's merchant account.

Also, one word of advice, if it is possible to set up: I'd recommend that you use TrustWave as your site scanning service for PCI DSS certification and NOT have the service Intuit uses for this -- their service should only be used for MOTO/offline payment scans. PM me if you are interested in more on this bit.
