Users can access their portal by going to the web address you chose for your practice, eg
https://mypractice.portal.accountants or by clicking the links in the email notifications they receive.
All open tasks you’ve assigned to them appear after they sign in. If the user has access to several portals, they can choose the one they want to view from the same portal site.
When viewing their task, the user can leave comments for you, and you’ll receive an email notification.
