QuickBooks Web Connector is a Windows application that acts as a bridge and allows web-based applications to exchange data with QuickBooks Desktop products.
The QB web connector app facilitates the automatic and scheduled transfer of data, including sales, invoices, or QuickBooks timesheets, between the web-based application and QB Desktop.

For a web service to integrate with Web Connector, it must implement a set of methods that are defined in the QuickBooks Web Connector WSDL. These methods allow the web service to communicate with the Web Connector using the same QBXML that the Desktop SDK and POS SDK use.
Adding a new Web service to the list of Web services that QBWC can communicate with is as easy for the user as downloading a file. (Files with a .qwc extension are XML files that describe a Web service designed to interact with QuickBooks and are opened automatically by the QBWC.) Users of QuickBooks’ online banking features will immediately recognize the user interface because it was based on the Quicken One Step Update feature.
