Invoicing software that knows what is paid and what is late

The status follows the payments you record. A new invoice is Unpaid, it becomes Partially Paid when some money is logged, and Paid once the full amount is in. You can also cancel an invoice. Nobody has to pick the status from a list.

Each invoice has a live Overdue flag that turns on after its due date passes. It is separate from the paid status, so an invoice can be Partially Paid and Overdue at the same time, and you can filter your invoice list to find them.
