Audit trail

Actions worth questioning later are recorded with who did them and when. Among them:

• Successful and failed sign-ins, with the failure reason
• Refunds — with the reason and the staff member
• Stock adjustments — with the reason, before and after quantities
• Register open and close — including who, the float and the variance
• Repair status changes and every customer notification sent
• Full data exports, including which tables were included

Because PIN approval attributes an action to a person rather than to a shared login, "who authorised this?" has an answer.
