The problem
The cost of not knowing who is on site
Attendance and progress on a work front are usually tracked on paper, in chats and in spreadsheets. By the time the information arrives, it is too late to act.
Paper lists and spreadsheets
Duplicate entries, signatures that are hard to verify and days spent consolidating the week.
No evidence
Nobody can prove where or when each person clocked in.
Late reports
Today's progress arrives tomorrow, by phone call or in a loose message.
Scattered information
Photos, notices and urgent issues get lost in personal chats.
How it works
Three steps, no friction
There is no app to install and no long training: a numbered menu guides every step from the worker's own WhatsApp.
- 01
Crew members write on WhatsApp
Clock-in, notices, urgent reports and clock-out through a numbered menu. Nothing to install.
- 02
The system stores the evidence
Every record keeps its photo, map location, site and Mexico City time.
- 03
Management sees and decides
Real-time panel, automatic weekly report and an alert to the site lead about who is missing.
Built for construction sites, not adapted from the office: photo of the work front, location and a log of progress and pending tasks when the shift closes.
