In Redmine, you might come across terms like contact, company, and user. Below you will find differences:
- Contact in Redmine is usually our customer (not a company). They don't need to have a Redmine account and can receive and send emails to you despite that
- Company is the same as contact, but it has checkbox Company checked
- User is anyone that has an account in Redmine
