CSA (Customer Without Service) is an intelligent solution developed to identify and monitor customers who have not yet been served in a store or sales environment. The system operates in real time, indicating the department where the customer is located, allowing available salespeople to be notified and able to promptly offer assistance. In this way, the CSA not only ensures that no customer is left unattended, but also optimizes the service flow.

Main benefits:
- Improved customer satisfaction: By quickly identifying unattended customers, the system ensures that each person is monitored, providing a more pleasant shopping experience.
- Agility in service: Direct communication between the system and sellers speeds up the customer approach and support process, reducing waiting time.

This tool is essential to ensure that each customer is served efficiently, without losing sales and improving control within the establishment.
