What you don't measure people don't respect
An on-time employee is a committed employee
No one should be late for anything that benefits them
How many objectives can be reached if we use all our available time wisely?
A business without boundary systems is a business in chaos
South African time and attendance software in the cloud — live attendance, payroll-ready timesheets, reporting, and terminal health in one system.
Zack fingerprint clocking terminals with WiFi, 5G, and offline sync — built for offices, factories, and remote South African sites.
Clock in on Android or iOS with GPS geofencing. Field teams and group clock-ins stay location-verified without a wall-mounted terminal.
A local support team that answers the phone — onboarding, payroll cut-off, and terminal issues handled by people who know Zeroslack.
We set up sites, shifts, Zack terminals, and payroll export with you in the first month so the time and attendance system is actually used.
Export hours, overtime, and deductions ready for payroll — including API sync with the payroll systems South African businesses already use.
Extend Zeroslack with tools for costing, management visibility, employee self-service, access, live attendance and AI-driven insight.
Allocate labour hours to jobs, sites or cost centres so you can track true project costs, compare estimates to actuals, and protect margins.
Give managers real-time workforce visibility on mobile — with push alerts, approvals and attendance oversight wherever they are.
Give employees access to their own timesheets, hours, leave applications and company announcements — so HR and managers spend less time answering the same questions.
Control doors, gates and turnstiles directly from the terminal with built-in relay functionality — attendance and access in one system.
See who is in and who is out in real time on an in/out wall board — ideal for reception, operations floors and control rooms.
Your workforce generates thousands of data points every week. Zeroslack tells you what matters — short, actionable insights on attendance, punctuality, hours and terminal health.
Fingerprint clocking with WiFi, 5G, and offline sync — fixed for the floor, portable for the field.

Fifty years in South African workforce management — we know what holds up on the floor, not only in a demo.
Zack terminals and Zeroslack software are designed and supported in South Africa, so you are not waiting on an overseas vendor.
Built by engineers who also support it — the people who write the time and attendance software answer when something breaks.
Power cuts, dusty sites, remote clocking, and multi-site retail: Zeroslack is built for how work actually happens in Africa.

Yes. Zack fingerprint terminals (fixed or portable) handle clocking; Zeroslack V3 processes attendance, reporting, and payroll-ready exports in one system.
No. Mobile geofencing is available as part of a Zack terminal deployment with Zeroslack packages — it extends field coverage and is not a phone-only product. See mobile clocking.
Zack terminals can store clockings locally and sync when connectivity returns — important for remote sites with unreliable power or network. More on offline clocking.
Yes. Clockings become payroll-ready timesheets with hours and overtime, with export and API sync options for systems South African businesses already use. See payroll exports.
