Kenyan employment law and your contracts set minimum rules. Confirm with your HR adviser; the software only counts time. ## Set it in the software 1. Open Attendance > Timetable Setting and edit the timetable. 2. Tick **Enable OT**. 3. Set the OT settings your version offers for weekday, rest day and holiday. 4. Save and recalculate. ## Read the result The daily total report and the monthly summary list OT hours. Compare a few people's raw punches with the OT shown to confirm the rule behaves as you expect. See [Calculate](https://qyvea.co.ke/zkbio-time-net-calculate-attendance). ## Avoid disputes - Show staff how OT is counted. - Never edit punches to add OT without a written approval. - Keep a log of approvals with the pay period file. ## To payroll Pass OT hours to payroll. See [payroll hours](https://qyvea.co.ke/zkbio-time-net-payroll-attendance-hours). ## A typical scenario A factory enabled OT with a 30-minute minimum and agreed weekday and Sunday rates in writing. Payroll used the monthly OT hours from the report and the number of OT queries fell to almost none. *Illustrative example based on common cases, not a named customer.* ## Common mistakes - No written OT policy. - Enabling OT for everyone by default. - Editing punches to create OT. - Ignoring holiday rates. - Not checking rounding. ## Quick checklist 1. Policy written 2. OT enabled where allowed 3. Rules set 4. Calculated 5. Spot-checked 6. Approved by management ## Frequently asked questions Does the software calculate OT pay? It calculates hours. Payroll applies rates. Can OT count only when approved? Handle approval outside the software, or use a manual record that you control. Why is OT zero? OT may not be enabled in the timetable, or there are no punches beyond check-out. Can I limit OT per day? Use your version's OT limits if available.
