This lesson explains the difference between the Delivery and Commercial Contacts within the Assignment/Project record
Delivery Contact - The person you've dealt with at the job level, that pulls through into the assignment. They will also be the contact that receives submitted timesheets for approval.
Commercial Contact - When you raise an invoice from an assignment this person will automatically be pulled into the invoice. They can also be used as a secondary timesheet approver.
Invoice Contact on Company Record - Overrides the commercial contact when invoices are created. The Commercial contact is secondary to this field.
*If you choose to have the commercial contact as a secondary timesheet approver, please note that when a candidate submits their time both the delivery and commercial contacts will receive alerts to approve the time, and whomever does it first will be the approver.
