Time clock for stationery stores: working-time record with no devices
Short answer
A stationery store can meet the electronic working-time record requirement with a QR code printed and posted on site, which each person scans with their phone. The law requires recording each person's start and end time; it does not require a wall-mounted time clock.
How work happens at a stationery store
A stationery store has salespeople, cashiers and copy-shop staff, with school-season hours and peaks at the start of classes. That creates three challenges for measuring working time:
- Back to school concentrates the year's overtime.
- Temporary staff are hired.
- The permanent team is very small.
What the law requires of stationery stores
Since the 2026 reform, the Federal Labor Law requires recording electronically the start and end time of each worker's workday (article 132, section XXXIV). Failing to do so is fined 250 to 5,000 UMA. The STPS will define who it applies to and what exceptions there will be. The details are in the reform guide.
Work peaks. Overtime has a weekly cap: 9 hours at double time in 2027, with a maximum of 4 per day on no more than 4 days, and never more than 12 total hours in a day.
Hourly or temporary staff. They have the same working-hour limits and must also be recorded.
How to record working time at a stationery store
- Register the workplace and its shifts.
- Print the QR code and post it at the entrance or next to the register.
- Each person scans it on arrival, when leaving for a break and when going home.
- At the end of the day you review what does not add up and download the report whenever you need it.
Example. August temporary staff are added in minutes and removed when the season ends.
Calculate your overtime
How to do the math by hand
Take a salary of $400 per day on a day shift. The ordinary hour is worth 400 ÷ 8 = $50. In 2027, with 11 overtime hours in the week, the first 9 are paid at double time (9 × $100 = $900) and the remaining 2 at triple time (2 × $150 = $300). Total: $1,200.
Common mistakes at a stationery store
- Keeping attendance from memory or in a notebook.
- Recording the clock-in and forgetting the clock-out.
- Covering peaks only with overtime, until exceeding the weekly cap.
- Not recording temporary staff because they only come in for one day.
What to check every day and every week
Every day.
- Who did not record their clock-in or clock-out.
- Departures later than planned.
Every week.
- Each person's overtime against the weekly cap.
- Days when someone came close to 12 hours.
- Rest days that were actually taken.
How much an overtime hour costs: example in pesos
Suppose a daily wage of $350 on a day shift. The ordinary hourly rate is $43.75. One overtime hour at double time costs $87.50 and one at triple time, $131.25. If a person works 9 overtime hours in a week in 2027, that is $787.50 extra.
It is an example to show the calculation, not a reference wage for the sector.

Frequently asked questions
Does a stationery store need to buy a time clock?
No. The law requires an electronic record of working time, not a device. An app on a phone complies.
What options are there for recording working time?
An app on each person's phone, a shared tablet or a clock connected to a system. All three comply if they generate an electronic record per person, with a start and an end time.
Can I ask for more overtime in peak season?
The weekly cap is not extended for the season. It helps to plan relief staff.
Does temporary staff also clock in?
Yes. Their record is kept even if they work only one day.
Does salary go down if fewer hours are worked?
No. The reform prohibits lowering wages and benefits because of the reduction in working hours.
