Coffee Shop in Rosebank: Timeclock Uncovers R3,200/Month in Ghost Hours

The business

A coffee shop with counter service and a small seating area near The Zone in Rosebank, Johannesburg. Monthly turnover of R85,000 to R110,000 depending on season. Six staff including two baristas, two counter staff, a kitchen hand, and a part-time weekend employee. The owner managed the shop Monday to Friday but was rarely present on weekend shifts.

The problem

Labour costs were consistently 34 to 36 percent of revenue — well above the 28 to 30 percent target for counter service. With staff on largely fixed shifts and wages, the owner could not identify where the overrun was coming from. The previous POS had no timeclock feature, and staff recorded their own hours on a paper sign-in sheet left at the counter. Nobody checked it.

The switch to MangoPOS

After switching to MangoPOS (R299 once-off setup, no monthly software fee), the owner activated the staff timeclock with PIN-based clock-in and clock-out for all six employees. Within the first week, the owner had a clear record of actual versus scheduled hours for every shift across both weekday and weekend trading.

The result

The first monthly review revealed 47 hours of discrepancy between scheduled hours and paid hours. Staff were clocking in up to 25 minutes early, staying on after shifts without authorisation, or having colleagues clock them in before they arrived. At an average wage of R68 per hour, that added up to R3,196 per month in hours paid but not validly worked. The owner addressed the issue with two direct conversations — no dismissals — and implemented a rule that clock-in and clock-out required physical presence and a manager check on weekend opens. Within one month, labour percentage dropped from 35.4 percent to 29.1 percent.
