On Dashboard you’ll see two green buttons, saying “New Invoice”, one on the left navigation panel, and another in the top right corner. Click any of those two and you’re good to go.

From the menu click on Recurring Invoices and then the button New Recurring Invoice.

This will take you to the invoice creation page where everything is the same as in an ordinary invoice, except that Invoice Data is obviously auto-generated.

When you're done with the actual invoice click save. This will take you to the page where you will be able to set the schedule for your invoice to be created and sent.

That's it! Now this invoice will be automatically generated and sent according to the schedule.
