To assign a license to someone in your company for them to use, you must add them as a user. When you are logged into GovSpend go to the drop-down menu in the top right corner next to your name and select settings. 

Once the screen loads, you should see the option to invite user in the top right corner. This will bring up a prompt for you to fill in the new user's information. 

In this same window where you added your new user, you can manage them. You can edit their permissions and what they are able to do. You can see when they last logged in, you can resend their invite, and you can remove them as a user.
