The HOC Customer Record
All the nonprofit organizational records in the system have a type of either, Civic Organization, Faith-based Organization, Foundation, Government Organization, Nonprofit or School.
However -- one record in the system has a unique 'type' in its record: HOC Customer
Look up your organization's name in search, and you'll find the one record designated as type HOC Customer. This record has special significance in the system,
Even though your organization is technically a nonprofit -- you MUST leave this record designated as type: HOC Customer
Without a HOC Customer Record the system has no way to identify who the owner of the site, who is the managing organization of affiliate-managed volunteer opportunities,
Do not change the type of this one HOC Customer record. (And do not assign the type of HOC Customer to any other organizational record).
Even though everyone on your staff has a User record and a Salesforce license - you may find they don't yet have a Contact record.
You will need to make sure there is a contact record for any staff member who ever wishes to volunteer or act as opportunity coordinator for an opportunity.
Only contacts can be made Opportunity Coordinators or connected to opportunities and occurrences.
