We currently use Teapplix software to download our paypal sales into quick books (using e-junkie as our shopping cart with all payments either via paypal or credit card processed by paypal pro) - it works great.
They currently support direct integration between a number of carts and quickbooks direct - same as consolbyte with e-Junkie and quick books.
I have requested to Teapplix that they develop an interface with e-junkie as this will enable more data to be interfaced
If any one else is interested, I would appreciate you contacting Teapplix direct ( <firstname.lastname@example.org>; ) and also make a request for an integration.
If anyone wants to know more about Teapplix - please add to this topic
