Reading an order
Every invoice raised in the last thirty days appears on the Orders screen, one row per invoice. A row tells you who owes the money and where the invoice has got to.
The amount is what the customer owes on that invoice, before any credit note. The status is one of Open, Paid or Overdue; an invoice becomes overdue thirty days after it was raised.
This page exists so that the screenshot has somewhere to be installed. It is the documentation the recipe is written for.
