If you provide complimentary tickets to your sponsors, it is easiest to create a ticket type for each sponsor level, then sell or issue the ticket to each sponsor at that level.
This allows you to:
- issue the tickets,
- designate the portion of the sponsorship that is considered a charitable contribution,
- record (or process) the payment
- generate a sales receipt for the payment.
Create ticket types for each sponsorship level:
Go to Admin > Site Settings > Ticket Sales > Ticket Types > Add New
