Online booking
Customers choose the service, professional and time from a link, without calling or waiting for a reply. They only see slots that are actually free.
Scheduling & bookings
Your customers book on their own.
From one professional with their own calendar to a centre with many: online bookings at any hour, WhatsApp confirmation and reminders, synced with your Google Calendar and a waiting list for cancellations. Lía books, moves and cancels appointments from the chat.

Waiting list
A cancellation is no longer a lost slot.
Anyone who couldn't find a slot joins the waiting list. When someone cancels, Lía messages the people on the list on WhatsApp to offer them the slot. Your calendar fills itself back up, without calling anyone.

The appointment is cancelled from the chat or from your calendar and the slot frees up instantly.

What's included
A calendar that runs itself.
For any business that works with appointments: consultations, sessions, classes or services, with one calendar or many.
WhatsApp confirmation and reminder
Every appointment is confirmed and the customer gets a reminder beforehand, with the option to confirm. Fewer no-shows and fewer empty slots.
A calendar per professional and location
Each person or location has its own services, hours and capacity. No overlapping bookings, even with several of you working at once.
Lía handles appointments in the chat
Your AI assistant offers slots and books, reschedules and cancels appointments while chatting with the customer on WhatsApp or Instagram.
Synced with Google Calendar
Each team member connects their own Google Calendar and keeps their appointments in sync, without entering them twice.
A deposit when they book, if you want
Ask for a card payment upfront when customers book, through Stripe. Ideal for long or high-demand services.
How it works
Your calendar open for bookings in three steps.
1
Set up your services and hours
Enter what you offer, how long it takes, who provides it and when. Or ask Lía and it sets it up with you.
2
Share your booking link
Put it on your website, your Instagram profile or WhatsApp. Lía also offers appointments when someone asks in the chat.
3
Let your calendar fill up
Appointments come in confirmed, reminders go out on their own and all you do is check your day.
