What Trumba is
Trumba is web-based event and calendar software from a Seattle company founded in 2003. Its Base Subscription costs $99.95 per month, billed monthly, and includes unlimited calendars and events. Listed event tools include registration forms, ticketing, onsite check-in and attendee email. Trumba does not list an attendee app or exhibitor tools. A 30-day trial is available, but there is no free plan. Additional Seats cost $30.00 per month so more users can manage assigned calendars. Event Submission costs $50.00 per month for a website or intranet form collecting proposed events. Custom Objects costs $50.00 per month for directories and selectable attributes covering buildings, rooms, instructors and similar entries. Paid Registration is listed at $1.00 per month; payment gateway processing fees are charged by Trumba, while free events have no Trumba transaction fees. Client Support Services costs $200.00 per month and includes two free support hours for new accounts.
