You are able to set reminders for expenses so that Admins, Managers and Expense approvers can be reminded to pay expenses or submit expenses.These reminders will be sent to whoever you set them for leading up to an expense deadline.
To do this, navigate to your Company Settings and open the Reminders tab.
Clicking Add Reminder will prompt a new dialog box to appear. Here you can set who should receive an e-mail and dashboard notification, when they should receive it, and what the notification is about (either expense submission deadline or expense payment deadline)
You can set up as many reminders as you need for your staff.
