CASE STUDY
Grup Caliu · Building construction and maintenance · Barcelona
From the call-out to the invoice: every emergency in one system
- Custom ERP
- Field team apps
- Voice agents (Voice AI) (in development)
- WhatsApp and omnichannel agents (in development)

Grup Caliu carries out renovations, refurbishment and 24/7 emergency work in Barcelona buildings, working with property managers. It now runs quotes, emergencies and invoicing from a single platform.
The challenge
Quotes in spreadsheets and emergencies coordinated by hand, from the call-out to the invoice.
What we built
- Quote management.
- A portal that follows every emergency from start to finish (from call-out to invoice), including from the operatives' phones on site.
- Invoicing and margin tracking.
In development: an AI assistant that handles incidents by phone, WhatsApp and email and helps coordinate the team.
