Day, week and month views with per-professional colors
Switch from day to week to month with one click. Each professional has their own color and lane; you see at a glance who's loaded and where the gaps are. Designed to be read, not decoded.
Your whole calendar
on a single screen
Tomorrow's eight appointments are already in place: the two that came in last night through WhatsApp, the regular client who emailed, the three from the booking portal and the one you wrote down in person this morning. One screen, anti-overlap to the second and a free plan forever to get started.

What is an online calendar for service businesses?
An online calendar for service businesses is a digital appointment management panel with day, week and month views that centralizes bookings from multiple channels (WhatsApp, web portal, email, walk-in), prevents overlaps in real time and supports rescheduling by dragging. Marai includes it in the free plan with one professional and 50 monthly appointments.
The problem without a real online calendar
-
The notebook and the team's WhatsApp group don't match
You write on paper, your coworker replies on WhatsApp, a third professional uses Google Calendar in their own way. Three versions of the truth and, by closing time, two clients booked for five o'clock.
-
Rescheduling one appointment takes three phone calls
When a client asks to move a time, you stop what you're doing, check the notebook, call the next client, confirm with the professional. Every change costs you fifteen minutes — and the information still arrives late.
-
You lose bookings because you can't reply in time
The message comes in at 10 PM when the place is already closed, you see it the next day, you reply and the client has already booked somewhere else. Without a calendar that takes bookings on its own, every hour of late reply is a lost appointment.
What your online calendar does with Marai
Drag-and-drop to reschedule on the spot
Grab the appointment with the cursor, drop it on another slot and the system notifies client and professional. No forms, no calls; the change is logged and the old slot opens up for new bookings.
Real-time anti-overlap
Before confirming any appointment — bot, portal or manual — the system checks availability to the millisecond. It's impossible to end up with two clients booked for the same slot with the same professional.
Per-professional schedules with exceptions
Each team member sets their weekly schedule and adds exceptions: vacation, training, days off, reduced seasonal hours. The portal and the bot stop offering those slots automatically.

What is Marai's online calendar?
It's Marai's main panel (Settings → Calendar) where every appointment from your business shows up. Each appointment includes professional, service, client and duration; confirmed, requested and blocked appointments are visually distinct. The Free plan includes the full calendar for one professional with 50 monthly appointments; Starter, Pro and Business scale professionals and remove the limit.
How does the online calendar work?
- Activate the free account and the wizard sets up hours, professional and first service in three steps.
- Connect WhatsApp, the booking portal and Google Calendar from the Starter plan to receive bookings from any channel.
- Bookings land in the panel and the calendar updates instantly with real-time anti-overlap.
- Drag appointments to reschedule, mark attendance at closing and the client reliability score recalculates itself.

Frequently asked questions about the online calendar
Is it really free?
Yes. The Free plan is permanent and requires no credit card: it includes the full calendar for 1 professional with 50 appointments per month, waiting list, email reminders and CSV export whenever you need it.
How many professionals can I add?
Free allows 1 professional. Starter (€29/month) goes up to 2, Pro (€59/month) to 5 and Business (€99/month) up to 15. Each professional has their own schedule, services and calendar color.
How do I reschedule an appointment?
You drag the appointment with the cursor from its current slot to the new one. It updates instantly on the calendar, the client gets an automatic notification and the previous slot opens up for new bookings. No forms, no phone calls.
What happens if two people try to book the same slot at the same time?
The system checks real availability to the millisecond before confirming each booking. Only the first request closes; the second is automatically offered the next available slots. Double bookings are impossible by design.
Can I set different schedules per professional?
Yes. Each team member sets their regular weekly schedule and adds one-off exceptions: vacation, training, days off, reduced seasonal hours or local holidays. The portal and the bot stop offering those slots automatically.
Which channels can I take bookings from?
Five channels feed into the same calendar: WhatsApp (with the AI bot from Starter), public booking portal (from Starter), email, walk-in (with the client present) and manual (typed by you in the panel).
Does it work on mobile?
Yes. The web app is responsive and optimized for mobile and tablet: large type, drag-and-drop gestures, tap targets of at least 44 pixels. You can review and reschedule the calendar from any device with a browser.
Does it sync with Google Calendar?
Yes, from the Starter plan. Sync is bidirectional and real-time: appointments created in Marai appear in Google Calendar and vice versa. Each professional connects their own calendar; tokens are stored encrypted with AES-256.
What happens when I move from the free plan to a paid one?
Your calendar, your clients and your professionals stay in place. You upgrade from Settings → Subscription and unlock additional professionals, channels (WhatsApp bot, portal, Google Calendar) and advanced capabilities instantly. No migration required.
What is Marai?
