If you have turned on the 'Require Acceptance' option in your policy, users assigned to that policy will need to accept it before they can submit their expenses.
You're able to see who has accepted the company policy and who is still pending by following these steps:
1. Click the Account Name > Admin.
2. In the Account Setup section, click the Policies subheading.
3. Click View Users...
4. On the Accepted tab you can see which users have accepted the policy.
5. On the Pending tab you can see which users have yet to accept the policy.
