What's the difference between an individual and an organization profile?
Organizations represent a company or entity, while individual profiles represent a person. Organization profiles can have multiple team members (individual profiles) who have access to edit it and make financial contributions in its name. If a contribution or expense is for a company, it's important to use an organization profile so the correct billing information shows up on receipts and invoices. Organizations can also issue gift cards.
