Quick setup checklist
- Define roles — map real job duties (cashier, manager, inventory clerk) and list what each must do in the POS.
- Apply least privilege — give users only the permissions required for their role (avoid broad admin rights).
- Restrict high-risk actions — require manager approval for refunds, price overrides, voids, and payouts.
- Use unique logins — avoid shared PINs; enforce individual accounts so actions are traceable.
- Enable audit logging — turn on time-stamped activity logs and store them for regular review.
- Set limits and alerts — impose transaction limits and automatic alerts for suspicious patterns (large discounts, frequent voids).
- Protect credentials — enforce password complexity, session timeouts, and two-factor authentication if available.
- Test offline behavior — confirm how permissions apply when the POS runs in offline mode.
- Review and update — quarterly audits to remove old accounts and adjust permissions after role changes.
- Train staff — document procedures and run brief trainings on permission rules and approval workflows.
These controls reduce both theft and human error while keeping operations efficient. Combine role-based access with daily reconciliations and targeted reports to detect anomalies quickly and tighten controls where needed.
