You are able to set reminders for expenses so that Admins, Managers and Expense approvers can be reminded to pay expenses or submit expenses.
First, navigate to your Company Settings.
Next, go to the Reminders tab.
Scroll to the section for Expenses. Here you can see a list of reminders that have already been set.
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.
