I understand that, using this app, employees receive an email notification when new expenses are available.

They can click a link to see a list of their imported expenses.

With permission enabled, an employee can have access to expense reports. They can enter their own expense reports, view, and edit their own unapproved expense reports, view their own approved expense reports, and approve expense reports of their subordinates.

My question is:

Would all the cardholders need NetSuite accounts to login and edit their card transactions?
