Hello,
I have installed this module on a zencart 1.3.8 version site and although the test purchases were denied I made a test 1 cent product and was able to make the purchase with a real credit card. However, the transaction does not appear in my client's quickbooks application, only in the web interface (at https://merchantcenter.intuit.com/qbms).

When I spoke with someone at Intuit they told me I needed to use the web connector tool to properly sync zen cart with quickbooks. Is that a missing component of this plugin or am I doing something wrong?
Thanks,
Robert
