Download the Fathom Desktop Connector

The Fathom desktop connector can be downloaded from within Fathom.

To do so, first log in to Fathom, and click 'Add a company' in the top right.

Choose from QuickBooks, MYOB, or Excel.

You will then see the option to 'Launch the Fathom Desktop Connector'. This will download a '.exe' file. You can use this executable file to import your desktop files into Fathom.

Note: The Desktop Connector must be in the same location as the QuickBooks file. To check the location of the QuickBooks file, you can open the file in QuickBooks and use the 'F2' key or 'Ctrl +1' to reveal the exact location of the file.

Launching the Desktop Connector

The first time you launch the desktop connector, you are required to provide your email and password. These should be the same details used to log in to Fathom.

Your password will be remembered for the next time you use the connector.

Adding or updating company files

Adding a new company or updating an old one uses the same process. Simply click the 'Add Files' button and select the files from your computer. You can use CTRL and SHIFT keys to select multiple files at once in the file selector dialog.

The connector will indicate which files are new and which files are updating an existing company.

Note: You cannot add two companies with the same name.
