Payments Due list days overdue

This module extends the Payments and Due List so you can see how late each open invoice or bill is, and how much of the outstanding amount falls into each ageing bucket.

What you can do: - See a 'Days overdue' column on the Payments list, showing how many days have passed since the due date for lines that are still unpaid. - See extra amount columns, one per overdue term you configure, so the outstanding amount is shown in the right ageing bucket. - Create and manage your own overdue terms (name, from day, to day) from Accounting > Invoicing > Overdue Terms.

Business rules and automatic behaviour: - The number of days overdue is calculated automatically from the due date and today's date; it is only shown when the line still has an amount to pay. - Each overdue term generates its own amount column on the Payments list, and the amounts are filled automatically based on how many days overdue the line is. - Overdue terms cannot overlap: if a new term's day range overlaps an existing one, Odoo blocks it with a validation error. - Only accounting managers can create, edit or delete overdue terms; other users can only read them.

Where it appears: - The Payments and Due List view (account.move.line) gains the new columns. - A new 'Overdue Terms' menu is added under Accounting > Invoicing, with list and form views for the terms.
