When a Partner registers a Deal using the Deal Registration form, they have to associate the Deal with an end user Account and Contact upon registration. Channeltivity includes a set of standard fields for the Account and Contact information,  but you can add additional custom fields to capture more information by going to Settings > Deal Registration > Account or Contact > Add Field. Remember, this only applies to the Account and Contact fields on the Deal Registration form. If you want to capture additional information about the Deal, then you'll want to add custom fields to the Deal Custom Fields section.
