Every five minutes
- Queued email.
- Ticket escalations and scheduled ticket actions.
- The mail import, from its own cron job.
- New-release checks, every eight hours.
Once a day, in the hour you choose
- Invoices for services and billable items falling due.
- Reminders before and after the due date, and late fees.
- Suspension and termination of overdue services, as your rules say.
- Card captures, membership dues and lapsing, monthly gifts.
- Currency rates, the database backup and the daily report.
The dashboard's Automation Overview counts what the last run did: invoices created, card captures, overdue suspensions, inactive tickets closed, overdue reminders and cancellations processed.
