Can I get a daily report for how many tickets have been sold?

Yes you can. Once you've logged into your Billetto account, find your event in 'My events' at the top-left panel. Click 'Manage' next to the relevant event to be taken to the event's sales overview page. 

Navigate to the "Sales Overview" section in the left-hand side panel

Scroll down to the bottom of this page to find the subheading: Daily report 

Set a tick in the 'Enabled' box and define the e-mail address(es) you would like this daily report to be sent to.
