CTAS Work

Attendance, shifts and payroll — all in one app

Staff clock in from their phones, managers schedule and approve in a few taps, and payslips come out at month end following your own rules.

Clock in from a phone
Verified by GPS or the store Wi-Fi, with a photo when needed — no time clock to buy.
Flexible scheduling
Shift templates, several shifts a day, copy a week, breaks and calendars per department or store.
One-tap approvals
Leave, shift changes, missed punches and salary advances — requested and approved in the app.
A clear leave ledger
Monthly accrual, seniority leave and different policies for different teams.
Automatic payroll
Monthly, daily or hourly pay; allowances, overtime, holidays, insurance, income tax and mid-month estimates.
Processes & checklists
Recurring forms and checklists for opening, closing and cleaning — each with a clear owner.

Staff see their own hours and pay

Everyone sees their schedule, worked days, remaining leave and payslips — and the month-end questions stop.

Who is in, who is late, which requests are waiting — notifications reach the right person by role and department.
