At Your Service integrates with all QuickBooks Pro, Premier, and Enterprise editions for Canada, the United States, and the United Kingdom, versions 2002 through 2008. At Your Service does not integrate with QuickBooks Basic, EasyStart, or Mac editions.
QuickBooks Foundation Classes (QBFC) needs to be installed before At Your Service can communicate with QuickBooks. The first time that you access one of the QuickBooks export modules, QBFC will automatically be installed. Optionally, you may choose to manually install QBFC.
If At Your Service has already been installed then use Windows Explorer to navigate to the folder where it was installed (by default C:\Program Files\At Your Service on 32-bit systems or C:\Program Files (x86)\At Your Service on 64-bit systems). Optionally, navigate to the root folder of your At Your Service installation disk. Run the file named QBFC5_0Installer.exe and follow the directions on the screen.
