EventBrite offers an all-in-one tool way to manage ticket sales and attendance in addition to promoting the event. With EventBrite's easy to use event creation page, non-profits can build an event webpage complete with logos, images, and URL. 

Once the event is created, the non-profit can use social media such as Facebook, Twitter and LinkedIn to spread the word about the event. Attendees can use the same social media to announce their participation in the event and promote it as well.  
Payment is collected via EventBrite's credit card processor, PayPal, Google Checkout, and more. EventBrite's fees are automatically added to the cost of the ticket and EventBrite offers 501c3 organizations a reduced rate. 

EventBrite is optimized for mobile viewing so event participants can register and purchase tickets on the go. EventBrite has built in trackers so it is easy to see current registration and ticket sales. It also lets the non-profit know if the need to do more promotion to ensure a good turnout.

When it is time for the event, you can print a guest list or use the free Entry Manager app to check in people and scan bar-coded tickets with your phone. There is an optional At The Door mobile box office app for the iPad so you can sell tickets and collect customer information at the time of the event.
