Overdue tracking

An invoice becomes overdue once it passes its due date with a balance outstanding. The module tracks the outstanding total, the overdue total, and how many invoices are in each state.

Outstanding is the total less payments and less anything credited, floored at zero — so a credit note reduces what is chased rather than sitting alongside it.

Overdue invoices are chased automatically up to 180 days past due, then dunning stops. See Payment reminders.
