Customer Service Bot for Phone Repair & Sales

Mobile Device Repair & Sales
4-week implementation

Tecbox is a phone repair and mobile device sales business with 8 years of experience in Buenos Aires. With a team of 5 technicians and 2 salespeople, they serve an average of 150 customers per week.

Their main challenge was managing the high volume of WhatsApp inquiries while maintaining an excellent level of service, especially during peak hours and outside business hours.

The Challenge
  • High volume of repetitive inquiries about repair prices and phone availability

  • Support limited to business hours (9am-7pm), losing sales after hours

  • Slow response time during peak hours, causing customer abandonment

  • Difficulty tracking repair orders and notifying customers

  • Team overwhelmed answering basic questions instead of closing sales

The Solution

24/7 Support Chatbot

We implemented an intelligent WhatsApp bot that automatically answers frequently asked questions about repair services, prices and phone availability.

Automatic Quoting System

The bot receives the phone model and problem, queries a price database and generates an instant quote.

Order Tracking

Automatic WhatsApp notifications when the phone is ready for pickup, with reminders if the customer doesn't pick it up within 7 days.

Intelligent Classification

The bot classifies inquiries (sales, repair, tracking) and automatically routes to a human agent when necessary.

CRM Integration

All conversations are automatically logged in the CRM, with tags by inquiry type for later analysis.

The WhatsApp bot implementation completely transformed our operation. We used to lose customers because we couldn't respond fast enough, especially after 7pm. Now we provide 24/7 support at no extra cost, and our team can focus on what they do best: repairing phones and closing sales. The ROI was positive in the first month.
