- Set the Expected Acceptance Rate (%) based on your guest mix; casual parties run 60–70%, formal events 75–85%.
- Enter the Plus-Ones Percentage to account for guests bringing partners.
- Read Invitations to Send as your mailing quantity — this is higher than your target to offset declines.
- Use Estimated Total Headcount and the low/high Headcount Range to plan food, seating, and venue capacity.
