Before the invoice is sent out there are 2 emails set out to inform you that the domain/hosting is coming up for renewal. First one at 60 days before hand and secound at 30 days before hand.
At 21 days before due date the invoice is generated and sent out, at this point you can also see it in your client area.
At 14 days, 7 days and 1 day before the due date a reminder is then sent out.
Once the invoice goes overdue, a remind is sent out. If the account goes 5 days overdue there is a late fee added to the account.
At 30 days overdue the account is suspended.
At 60 days overdue the account is terminated.
