A customer disputes a price. A manager asks why a booking was cancelled. If the system only stores the current value, nobody can answer without guesswork.
Take a hypothetical property sales system where a unit's price was revised last week. The record shows the new figure. Nobody can say what it was before, who changed it, or whether the customer was quoted the old one.
The same unit shows the previous price, the new price, the person who changed it, the time, and the reason they entered when they saved it.
The detail depends on the event, but most entries worth keeping answer these.
Recording every click sounds safe and produces noise nobody reads, so the entry you need gets buried when something goes wrong. We agree with you which events need a history, who can review it, and how long records are kept. That list usually centres on money, approvals and access.
Readability matters as much as coverage. An entry that says "field 14 updated" helps nobody. Entries should name the record, the field and the person in words a manager can follow, and the people allowed to review them should be able to search by record, by person or by date.
A timestamp alone rarely explains a decision. Capture the context when it happens.
Support opens the order, sees the price change and its reason, and replies with facts instead of apologies.
Finance checks refunds and reversals made outside the normal rules, with the person and reason on each one.
A bulk import overwrote some records. The trail shows which ones and what they held before, so they can be put right.
An admin finds a user with rights they shouldn't have, and sees when and by whom their role was changed.
It supports your controls, but it isn't a compliance certificate. Specific regulatory requirements need their own assessment, and the trail is then designed to meet what that assessment asks for.
Yes. Scheduled jobs, integrations and automated rules are recorded too, labelled as such, so nobody mistakes an overnight sync for a colleague's edit.
Regular users can't. We agree with you who may view the full history, and entries are kept for the retention period you set.
Often, for the events that matter from that point on. History from before it was added can't be recreated, which is a good reason to plan it early, whether in a new build or a software takeover.
Tell us the question your history must answer, and we'll work back to the events worth recording.
