WhatsApp clock-in

Your team already has WhatsApp. Let them clock in there.

No app to install. No password. No tablet at the door. Each employee sends “entrada” to the Mesero number and the system records the shift, compliant with Spain's RD 8/2019. Breaks, exit, status, daily and weekly totals — all in the same chat. Works alongside the Mesero Fichar mobile app.

Why WhatsApp

Your team already knows how to use it.

Conventional clock-in apps struggle with adoption: another app to install, another password to remember, opening it each shift. Hospitality has high turnover and mixed teams, and that friction kills compliance. WhatsApp is the one thing everyone uses without training.

Zero install

No app to download. No password to remember. No pending update. The employee opens WhatsApp like any other day.

Works on any phone

Their iPhone, their old Android or a phone without the Play Store: for everyone it is the same, a message to Mesero.

The whole team, on day one

You generate a code per person and send it; one message links them. No training, and nobody has to install anything.

The flow

Link once. Clock in forever.

Only the first message requires a code. After that, Mesero recognises the employee by phone number and replies at once.

1. The manager generates a code

In Employees, on the person's record: a 6-digit code valid for 24 hours, and a link that opens WhatsApp with the message already written.

2. The employee links their phone

They send “vincular” and the code to the Mesero number. The reply carries their full name, and the phone is saved on their record.

3. And clocks in every day

“entrada” on arrival, “pausa” before lunch, “vuelta” on return, “salida” on leaving, or a tap on the buttons in each reply. Every clock-in lands on the time record with its time and source.

The chat's menu, with the options of someone clocked in. Example.

Commands

One word, or one tap.

The employee types the word or picks the option in the menu. The numbers follow the menu of the moment: once clocked in, 2 is clocking out.

  • entrada · salida: clock in and out, with the time and the day's total on the way out.
  • pausa · vuelta: the break, taken off the total.
  • estado · hoy · semana: whether they are clocked in and since when, and the day's or the week's hours.
  • horario · turnos: their upcoming shifts.
  • vacaciones: the days they have left (Pro plan).
  • documentos: the contract and payslips you share with them.
  • menu · ayuda · comandos: everything they can do.

The same chat does much more than clocking in: Mesero on WhatsApp

Compatible

WhatsApp and the Mesero Fichar app. Not “or”.

An employee can clock in on WhatsApp and out in the app, or the other way round: it is the same shift. When anyone clocks in or out, the database locks that person's open shift, so there are never two open.

If this happensWhat Mesero does
In on the app, out on WhatsAppCloses the same shift, no duplicate
Clocking in twice in a row“You are already clocked in”, no duplicate
Two clock-ins at once from two placesThe open shift is locked: there are never two
Who is clocking in?A PIN on the tablet and the QR; on WhatsApp, the linked phone
Where did they clock in from?Every clock-in keeps its source: app, WhatsApp, QR or web

Premium features

What you didn't expect to come over WhatsApp.

WhatsApp clock-in isn't a cut-down version: it is the same record as the app, through the chat.

Interactive buttons

Every reply carries up to three buttons (Clock in, Clock out, My status, Menu). One tap instead of typing, as in an app.

What about location?

WhatsApp clock-ins are not location-checked: they are marked “no location”. To check that staff clock in at the restaurant, switch the check on for the app and the web clock.

Automatic reminders

If someone forgets to clock out, a WhatsApp reminder reaches them the next morning, on a Meta-approved template.

In Spanish or English

Replies come in Spanish or in English, for a mixed team.

Anti-impersonation

The linked phone is the identity: only whoever has that WhatsApp can clock in as that employee. When someone leaves, the manager unlinks them with one click.

Full traceability

Every WhatsApp clock-in stores the time, its source and the number it came from. The Inspectorate sees when and how each hour was recorded.

No per-message fee

Not per clock-in, not per reply, not per reminder.

Messages go through Mesero's number, on Meta's official WhatsApp Business API, and they are included in the plan. Nothing to sign up for, no number of your own.

  • Meta's official API, with no intermediaries or unofficial apps.
  • No fee per employee: clock-in comes from the Starter plan.
  • No number of your own: your team writes to the Mesero number.
  • €0Per messageReplies and buttons.
  • €0Per reminderIncluded in the plan.
  • €0Per employeeThe whole team, no licences.
  • 24 hCode validityOnly the manager generates it.
