account_invoice_do
==================

Dominican Republic invoice helpers for Tryton.

This module extends ``account_invoice`` with operational fields commonly used
in Dominican Republic installations:

* salesman on invoices;
* due date, elapsed days, overdue days, and paid amount helpers;
* supplier reimbursement party;
* informational invoice line tax amounts by Dominican tax kind;
* optional cron methods to process posted customer and supplier invoices.

The tax amount columns are display helpers. They are computed from the line
amount and the selected taxes to make invoice entry easier to review; accounting
tax posting remains handled by Tryton's core tax engine.
