Veterinaria Gachen's
WhatsApp agent that books, cancels and reschedules appointments against each professional's real schedule. The code stays in the clinic's account.

- Industry
- Veterinary care
- Location
- Patagonia, Argentina
The problem
- Appointments were requested over WhatsApp and coordinated by hand across several professionals, each with their own schedule.
- Cancelling or rescheduling depended on someone reading the message in time.
- Payment receipts sent by clients were scattered across the chat.
What we built
- AI agent on the official WhatsApp API that checks each professional's real availability and books, cancels or reschedules appointments.
- Staff panel to confirm appointments, read every conversation and take over when a person is needed.
- Automatic reminders before every confirmed appointment.
- Receipts are stored automatically and linked to the appointment and the pet.
- The database rules out, by design, two active appointments at the same time with the same professional.
- Clinic website with built-in appointment requests.
Status
In production on the clinic's real number since late September 2026: over 100 confirmed appointments in the first three weeks. Next step: connecting the clinical management system for vaccine reminders.
