We just rolled out SupportBee on Google Apps Marketplace. If you are using Google Apps for your business, you can now add SupportBee and setup your users (agents/admins) in less than five minutes. What's more, you don't need to create a new login or remember a new password. You can login to SupportBee using your Google Account.
At the moment, you cannot link your existing SupportBee account with your Google Apps domain. This is only for setting up new desks. We are working on rolling this out for existing accounts. However, if you are an existing customer, please take a moment to review us there. We appreciate your help.
