Invoices are typically raised 14 days from the service expiring, with a reminder sent at 7 days out from falling due.
Details surrounding how our systems handle late payment (where we don't hear from you) are clarified in our Terms of Service.
Please review our Terms which apply to your service/s with us, in particular Section 3 of our Terms of Service which covers payments.
