Account Maturity Date Default

This module changes how Odoo handles the due date (maturity date) on accounting entries. When a journal item is created on a receivable or payable account and no due date is entered, Odoo now copies the date of the journal entry into the due date field.

The same rule applies when an existing journal entry's date is changed: any receivable or payable line that still has no due date is updated to match the new entry date. Lines that already have a due date are left untouched, so any date you entered yourself is never overwritten.

• Works on customer and vendor balances only (receivable and payable accounts).
• No new menus, screens or reports are added; the behaviour happens silently in the background.
• Affects account.move and account.move.line, the models behind journal entries and their lines.

This is useful for businesses that do not use payment terms and simply want the invoice date to act as the due date, keeping ageing reports and payment follow-up consistent without extra data entry.
