Zero install
No app to download, no password to remember. The employee links once with a 6-digit code, then Mesero recognises them by their number.
Mesero on WhatsApp
Your team already lives on WhatsApp. Let them work from there.
Clocking in is just the start. With Mesero each employee checks their schedule and next shift, their holidays and hour bank, opens their documents and signs the read receipt, sees who's on today, ticks off the day's tasks and sends a photo of any incident — all inside WhatsApp, with nothing to install and no passwords. And you, the manager, ask the assistant about sales and message the whole team in one go.

One surface
What other tools make “another app”, here is a message.
The problem with conventional HR tools isn't the feature list, it's adoption: install another app, remember another password, open it every time something happens. In hospitality, with high turnover and mixed teams, that friction means nobody opens them. Mesero puts the team features where your people already are: WhatsApp.
Tappable menu, not commands
Type “menú” and an interactive WhatsApp list appears with everything: clock-in, tasks, schedule, holidays, hour bank, documents and team. Tap, don't memorise.
By voice note too
Clocking in and out, the break and the return also work as a voice note. Mesero writes down what it understood before replying, so nobody clocks what they didn't say.
For the team
Everything an employee sorts out alone, bothering no one.
Type the word or tap the menu. No waiting for the manager to open a computer, no paperwork, no WhatsApp group where everything gets lost.
Schedule and next shift
Their shifts for the next 7 days, with next-week and tomorrow buttons. And on clock-out, Mesero reminds them when they work again.
Holidays · Pro
How many days are left this year, how many used and how many pending approval. No need to ask the office.
Hour bank
Hours worked against scheduled this month: ahead or behind. Transparency that cuts payroll disputes.
Documents with sign-off
Contract and payslips via a secure link protected by their PIN — never a public URL. They confirm receipt with one tap, recorded with the date.
Who's on today
Who's working today and on which shift. Handy for coordinating cover, knowing who's on the shift and who closes.
Task checklist
The day's tasks (opening, closing) in a list ticked from the chat. The manager sees what's done and what's missing.
Incident photos
A photo with a note — “fridge not cooling”, “broken table” — lands on the dashboard under Employees → Incidents, ready to resolve. Text alone works too: “incidencia: the coffee machine is broken”.
Ask how it works
“How do I request holidays?”, “how do I clock out?”: Mesero answers from the documentation, in plain language. How-to only; business data stays with the manager.
Full clock-in
In, out, break and return — even by voice note — compliant with Spain's RD 8/2019. See clock-in in detail
Automatic alerts
Mesero messages first when something changes.
It doesn't only reply — it notifies. With Meta-approved utility templates, the employee gets what matters in the chat they already check a hundred times a day.
🔄 Schedule change
When the manager edits or publishes the rota, everyone affected gets an alert. They text “horario” and see the updated week at once.
📄 New document
When a contract or payslip is uploaded, the employee is notified and opens it with their PIN. No more chasing signatures in the group.
📣 Team announcement
The manager sends a notice — menu change, meeting, policy — to the whole linked team at once, from Employees.
🔔 Clock-out reminder
If someone forgot to clock out, a reminder the next morning. Fewer open shifts, fewer manual payroll corrections.
For the manager
Ask about your numbers. It answers in the chat.
The owner or manager also links their WhatsApp and gets an assistant that reads live business data — without opening a computer, wherever they are.
- Sales on the spot: “how much so far today?”, “and last week?”, with the breakdown by payment method and the comparisons.
- Products and orders: “what's the top seller?”, “any open tables?”. By voice note too.
- Only for those allowed: on every question the assistant checks that this person may see the figures on the dashboard.
- It all reaches the dashboard: incidents to resolve and notices to the whole team, in Employees.
MeseroThe restaurant's assistant
How much so far today?
Today you're at €1,284.60 across 42 tickets, an average ticket of €30.59: €812.40 by card and €472.20 in cash. Top seller: ham croquettes (18). There are 3 open tables right now.
Privacy and compliance
Convenient doesn't mean careless.
WhatsApp is the door; Mesero puts the security behind it.
Private documents
Contracts and payslips are kept in private storage and open through a temporary, PIN-protected link. There is never a public address anyone could guess.
Identity by phone
The linked number is the employee's identity: only the owner of that WhatsApp account acts as them. When someone leaves, the manager unlinks them with one click.
Meta's official API
Built on the official WhatsApp Business API, with no intermediaries or unofficial libraries. Clock-ins compliant with RD 8/2019, with their source and time.
