Invoices & Certificates of Attendance

Registration Invoices:
Invoice receipts are downloadable from the confirmation email you received after registering under the Payment Receipt Information section. If the downloadable invoice receipt does not meet your needs or you need to have your confirmation email resent, please submit a request. Please include any additional customization you need for your invoice receipt in the request.

Certificates of Attendance:
You can download your Certificate of Attendance directly from your LFX dashboard by navigating to the “Past Events” section in the LF Events column. Please Note: We verify attendance through the registration system, and certificates will only be available for download after the event is completed.

Refund Policy

Cancellations:
If you must cancel for any reason, please sign back into your registration, click the “Register/Modify” button, and select “Unregister.” Refunds will only be issued for cancellations received two weeks prior to the main event start date (including bulk ticket invoice requests, co-located events, and add-ons), and will appear as a credit on the card’s statement 7 – 10 business days after cancellation. Refunds can only be issued on the card the original payment was made.

Please note that all refunds are subject to a 6% processing fee.

Substitutions:
If you are unable to attend, you may substitute another attendee in lieu of cancellation. To substitute an attendee, sign back into your registration, click the “Register/Modify” button, and select “Transfer Registration” on your confirmation page. If you need further assistance, email registration@linuxfoundation.org.
