Deploying AI Receptionists for Local Businesses with OpenClaw and Retell AI

A developer has shared a case study on deploying AI receptionists for local service businesses using OpenClaw integrated with Retell AI. The system addresses a common problem where 27% of calls to businesses like HVAC, plumbers, and lawn care services go unanswered because owners are often on job sites.

System Details

The implementation combines OpenClaw with Retell AI to create an agent that:

• Answers every call 24/7
• Knows the business's services, pricing, and hours
• Captures appointment requests
• Sends the owner an SMS or email after every call
• Includes owner verification via caller ID and PIN for checking messages by phone

Deployment and Results

One deployment took one hour from start to live. In the first week:

• 23 total calls handled
• 15 calls that would have gone to voicemail
• 7 appointments captured
• Total AI cost: $4.12 for the week

This type of integration demonstrates how AI agents can handle practical business functions like call answering, which is particularly useful for service businesses where owners are frequently away from the office. The low cost and quick setup time make it accessible for small operations.
