Once you have a Quickbooks Webconnector communicating, and the Quickbooks XML transferring data to and fro, then, you need some entities to put the data into. Beancount provides this entity and related bundles and the framework for dealing with them.
Quickbooks XML connects to the Quickbooks Webconnector module and provides exchange (input / output) of Quickbooks data with Drupal.
The Quickbooks Webconnector module (QBWC) allows standalone computers running Quickbooks or Quickbooks Point of Sale (POS) to use the Quickbooks Webconnector to exchange data with a Drupal site.
