How can I add/remove an user in my account?
You can create new users in Account/Users. But only Administrators can create new users. If there is only one user, it must always be an Administrator. You can create a Standard user by not switching on the Administrator option.
The difference between a Standard User and an Administrator is that an Administrator can create other Users and an Administrator can also see the invoices in Celery.
Also removing users is possible in Account/Users by clicking on the remove button that becomes visible when you hold your mouse above the user you want to remove. In that case Celery will ask you to choose a replacement user to take over any open pay runs processed by the user you want to remove. Please select one other user and click on the Remove button.
