Your sales manager lowered a discount from 15% to 10% last Tuesday. Your warehouse lead changed the reorder quantity on Product X. Your accountant updated payment terms on a vendor contract. Odoo tracks some changes in the chatter, but only for specific fields — and you have to scroll through unrelated messages to find them. Field Changelog Viewer shows every edit to any field you choose, right on the form. Add the widget to Credit Limit, Unit Price, Payment Terms, or any field you need to monitor. You see old value, new value, who made the change, and exactly when. No separate reports. No developer mode. No digging through mail threads. Sales ops can verify pricing changes before approving quotes. Warehouse managers can trace inventory rule tweaks when stock levels look wrong. Accounting can confirm who adjusted vendor payment terms and when. Pick the fields that matter to your business. The widget does the rest.
