Adding Supplemental Fees
Supplemental Fees let you attach additional charges as line items to your event's registration fees. This is useful for passing along costs like sales tax, environmental fees, facility surcharges, or any other fee that applies to registrations.
Supplemental fees can be set as either a fixed amount or a percentage of the registration fee, giving you flexibility depending on how the fee is calculated.
How to Add a Supplemental Fee
From your event dashboard, navigate to Registration > Supplemental Fees.
Click Add Fee.
Enter a Fee Name — this is what athletes will see as a line item during checkout (e.g., "Sales Tax" or "Facility Fee").
Choose the fee type:
Percentage — the fee is calculated as a percentage of the registration total (e.g., 8% sales tax).
Fixed — a flat dollar amount is added regardless of registration total (e.g., $5.00 environmental fee).
Enter the fee amount based on the type selected.
Save your fee.
Once saved, the supplemental fee will automatically appear as a line item on the registration checkout for athletes.
Tips
You can add multiple supplemental fees if needed (e.g., both a tax and a facility surcharge).
The fee name is visible to athletes at checkout, so use clear, recognizable labels.
If your region requires sales tax collection, a percentage-based fee is typically the right choice.
