Currently, EventCreate does not support changing add-ons after an attendee has completed registration.
Add-ons appear as secondary options on your registration form once a guest confirms they are attending, and they are locked after checkout.
After registration, you cannot:
Remove an add-on from an existing order
Edit or swap add-ons
Change add-on quantities
Once an order is completed, add-ons cannot be modified directly.
If an Attendee Needs to Cancel or Modify an Add-On
If an attendee needs to cancel an add-on:
Process a partial refund manually through Stripe
Go to Attendee List
Edit the attendee record
Add a note indicating:
Which add-on was canceled
That a partial refund was issued
This keeps your order data intact while documenting the change.
If an Attendee Wants to Purchase an Additional Add-On
Option 1: Delete the Order and Re-Register
If the attendee wants to add more add-ons to their original purchase:
This is the simplest option if they haven’t attended yet.
Option 2: Sell Add-Ons Using an Additional Form (Recommended)
If you want to:
Allow guests to purchase add-ons after registration, or
Allow guests who are not attending to purchase add-ons
You can create the add-on as an Additional Form (a separate purchase link). To set this up, follow this guide:
https://support.eventcreate.com/en/articles/8117409-additional-forms
Option 3: Convert the Add-On Into a Ticket Type
Another option is to move the add-on into its own ticket type: https://support.eventcreate.com/en/articles/2944722-how-to-create-or-edit-a-ticket
To allow attendees to purchase the ticket more than once using the same email address:
Go to Setup → Registration
Make sure RSVP No is unchecked
Go to the Advanced tab
Uncheck Unique Registration
This allows attendees to register again and purchase the add-on as a ticket.
Best Practices
Add-ons work best when selections are final at checkout
Use attendee notes to track refunds or exceptions
Use Additional Forms for post-registration purchases
Summary
Add-ons cannot be changed after registration
Refund canceled add-ons via Stripe and note the change
Delete and re-register to add add-ons to an existing order
Use Additional Forms or ticket types for flexible add-on sales
