The audit log is Tally's memory. Whenever something important changes — a settlement approved, a transaction voided, a buyer's credit edited — Tally writes a record of it.
Each entry captures:
who made the change (the user and their role),
when it happened,
what changed (the entity and the action),
the before and after values.
This is what lets the office answer "who changed this number, and what was it before?" without guesswork.
