Introduction

In real-world purchasing workflows, Purchase Orders (POs) often go through multiple revisions, prices change, quantities are adjusted and new products may be added even after a PO has been cancelled and reworked. While Odoo allows these changes, tracking what was changed, by whom and why can quickly become a challenge.

To solve this gap, we developed the Purchase Order Line Log Note addon for Odoo. This module ensures full transparency and accountability by logging every critical change made to Purchase Order lines, along with a clear reason for each modification.

Why We Built This Module

In many businesses, auditability and traceability are essential especially in purchasing. We noticed common pain points such as:

• No clear record of changes made after a PO is cancelled and reset to Draft

• Lack of accountability when unit prices or products are modified

• Difficulty understanding the intent behind changes during audits or internal reviews

This addon was built to enforce discipline in the purchasing process by making change reasons mandatory and automatically maintaining a detailed log in the Purchase Order history.
