Express Invoice can be set up to run as a mini web server, giving you and your employees access to Express Invoice over the Internet, from any location, as long as the main computer running Express Invoice is left running. Setting up Web Access from your local computer also enables you to assign login information for different employees, giving them varying levels of access to Express Invoice features.Once Web Access has been set up, you can login to the Express Invoice web interface and use the same features online as you do from the Express Invoice application.
