Trellis Paid Events Transition Frequently Asked Questions

As a reminder, the university’s Eventbrite contract will conclude in September 2026. All units must transition to Trellis Events, the centrally funded platform for managing free and paid events, before the contract official ends.

For more information, including step by step instructions on how to transition, visit our Event Services page.

No, there is nothing needed from your department to close the account. 
Yes. A recording of one of our initial Trellis transition sessions is available on the Event Services webpage. This includes a demo of Trellis Paid events, as well as details on how to request a Merchant ID, including how to complete the form required. 
No. Since the master contract is expiring, departments may not open individual Eventbrite accounts. Doing so would place liability on the department or individual.
If your department does free events and does not collect any payments, you will not need to create a merchant account. You will still need to be provisioned into Trellis for their free event service. Contact Makayla Nichols to schedule a discovery session.

While fees representing registration alone are not subject to Arizona sales tax, many additional offerings such as lodging, special meal options, materials, swag, add-on activities, etc., come with allowability restrictions and tax implications.

Questions about allowability of additonal offerings can be directed towards your Fund Account.
Arizona sales tax questions can be posted to FNSV-TaxServices@arizona.edu.
Paid virtual and/or hybrid events are not allowed at this time. These events expose the university to multistate sales tax compliance risk. The university is currently implementing a technology solution to ensure multistate sales tax compliance. Details will be provided when implementation is complete. 
 

Events that do not charge fees to attendees are allowable. If no fee is charged, there is no sales tax implication. 

No. Merchant Services creates merchant accounts and handles payment setups. Trellis manages the event platform, user access, training, and Merchant ID connections

No. UITS oversees AccessFlow. Support requests can be submitted here.

PCards would not be available, so internal billing must be used. For purchases from another university department, please review the available purchasing methods. 

No. Merchant Services will create your account. You will receive login details once setup is complete.

You will receive two emails once you have had your PayConex account registered. The first will have the a subject line that reads "A new Bluefin PayConex gateway has been created for you." This is a welcome email that will include an email with a login link.  

The email that will have your account number, account name, and username will come from the second email that will have the subject line "PayConex - Account Setup Completed". 

Please allow for both emails to be sent. Once both have been sent, use the information in the second email to complete the registration through the link in the first email. 

There is no payout cap that we are aware of. When someone registers through a Trellis Event, the money is auto-booked to the account through the Merchant ID that you set up.

There are currently no fees associated with using Trellis Events, but there are fees associated with the Merchant ID account that you set up for processing your payments. Each option has different fees. Transaction fees would apply to payment and refund transactions.

  • For Authorize.net accounts there is a 3% card processing fee and the following fees for the account: $49 setup fee, $16 monthly fee, and $0.10 fee per transaction.
  • For Bluefin/PayConex accounts, there's no setup or monthly fee, but there is a 3% card processing fee and a $0.10 fee per transaction. 

Bank of America takes out the credit card fees on their end before it shows on the university account, but Bluefin/PayConex will reach out to you directly for payment on their end via email. Most departments pay with a PCard.

Refunds are not automated in Trellis. You can manage your own refund policy. Trellis allows anyone who is a Paid Event Organizer to process refunds directly in Trellis. You can do full or partial refunds before the event. You cannot refund more than someone has paid. Refunds after the event would have to be processed through your Merchant ID account.

Yes, multiple people from your department can have access to your events in Trellis. You would just need to request access for each of them through AccessFlow.

There is a lot of flexibility in your event setup through Trellis. You can add questions to collect information during registration.

A short demo is included in the Trellis Events information session recording.

If you have additional questions, you can schedule an Trellis Events discovery session with Makayla Nichols.
