You need to prove who changed the discount on order SO4782. Or track every delivery date edit on rush shipments. Or show your auditor exactly when payment terms were modified on vendor bills. Odoo's built-in audit log captures everything or nothing. Writing custom tracking for each field burns developer hours you don't have. Field Change Logger lets you turn on tracking for any standard field on any model. Pick the fields once. Changes are logged automatically from that point forward with user, timestamp, old value, and new value. Export to Excel or CSV when you need to share proof with finance, ops, or external auditors. Installation takes 90 seconds. Enabling tracking on your first field takes another 30. No Python. No custom models. No recurring developer requests every time a department asks to track something new.
