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 "Guest list & Reports" section in the left-hand side panel

Here you will find the subheader "Daily report". Enable the option by clicking the slider, entering the email you wish to receive the reports and click submit
