The admin of the account is the person who went through the self signup process and inputted his/her credit card on file. The credit card that the admin inputs is the credit card that will fund everyone’s line of credit. There can only be one admin for every Self-Service Corporate Account who has access to manage the account.
There can be many diners in a single corporate account. The diners are the people receiving the line of credit to spend. These diners cannot manage line of credit budgets or any other details specific to the corporate account that they are associated with, only admins have the ability to make such changes.
Both the admin and diners must create Grubhub credentials to place orders on grubhub.com.
