If you need to schedule an invoice to send at a later date, you can customize the send date when you create the invoice.
As you build the invoice, you can edit the Scheduling options. You can choose to send the Invoice immediately or at a later date. You can also customize the payment due date.
You can even set up a recurring series of Invoices to be sent on a regular schedule, you can learn more about recurring invoices here.
One important thing to note is that Scheduled invoices are sent out at 8:00 A.M. PST on the date they are scheduled.
