[Internal Survey] Over 50% of Inquiries to Detective Agencies Occur After Business Hours

Denwa Daikou Service Co., Ltd., a Tokyo and Osaka-based BPO provider specializing in telephone answering services, has released an internal survey on "after-hours inquiries" based on operational data from multiple industries utilizing 24-hour response systems.

The survey analyzed inquiry trends—excluding sales and nuisance calls—across six sectors: judicial scrivener offices, law firms, chiropractic clinics, detective agencies, staffing agencies, and automobile buyers. The results confirmed that all industries receive a significant number of inquiries outside standard operating hours. Notably, in the detective agency sector, approximately 53% of all inquiries occurred after hours. Other significant findings include chiropractic clinics at 38%, staffing agencies at 31%, and law firms at 24%, suggesting that traditional daytime-only response systems are failing to capture a substantial portion of potential business opportunities.

### Key Findings by Industry
- **Detective Agencies (53% After-Hours):** The highest ratio among surveyed industries, with continuous activity even during late-night hours (12:00 AM – 5:00 AM).
- **Chiropractic Clinics (38% After-Hours):** A high volume of inquiries occurs on weekends (24.5%) and during the 7:00 PM – 8:00 PM window, reflecting urgent booking needs.
- **Staffing Agencies (31% After-Hours):** Significant demand exists after 6:00 PM and on weekends (15.1%).
- **Law Firms (24% After-Hours):** One in four inquiries occurs outside business hours, particularly between 7:00 PM and 8:00 PM.

### Impact of Missed Calls
The survey identifies severe opportunity losses caused by missed calls, including the leakage of leads to competitors, decreased customer satisfaction, and a direct negative impact on advertising ROI (Return on Investment) due to higher acquisition costs. Many companies reported that while they recognize the need for 24-hour support, labor shortages and the high stress of constant phone duty on staff make internal management difficult.
