See below for a list of emails the Accountant will receive as the project moved forward in Status, and as money is moved during the course of the project.
If the accountant does not wish to receive email notifications on the topics above, they can go to Accounting>Email Notifications>uncheck the box next to the notification email, and it will no longer be sent when that task is performed.
NOTE: This is a Global Setting so the option to send or not send will apply to all Accountants at your company. Certain actions will still permit the PM to selected an Accountant and and send the notification e-mail anyway. If you are receiving these notifications and do not want them, let your Project Managers know they do not need to check the Accountants name and/or send the notification e-mail if they can dismiss it without sending.
