At Elitz Building Management, approximately 300 incoming calls from tenants are received daily, handled by only 6 to 7 staff members. To prevent miscommunication and improve response quality through accurate information sharing, the company began using KaiKura in December 2020. Today, by leveraging features such as caller customer information display and SMS functionality, the company has achieved smoother customer service. This release highlights excerpts from the published interview, showcasing implementation benefits and organizational usage practices.

Background for Adopting KaiKura: Aiming for Visibility of Customer Information and Smooth Handovers

Elitz Building Management places high importance on providing prompt and accurate responses to tenant inquiries. However, details such as property names and room numbers are often difficult to understand over the phone, leading to time-consuming handovers between staff. Especially for urgent inquiries like water leaks or fires, improving the accuracy and speed of internal coordination became a key challenge in order to respond quickly while empathizing with tenant concerns.

Changes After Implementing KaiKura: Improved Response Quality and Operational Efficiency Through Customer Information Visibility

Since implementing KaiKura, tenant names, property names, and room numbers are now displayed automatically upon receiving a call. This immediate identification of callers enables accurate call transfers to the appropriate staff, reducing misunderstandings and missed communications.

・Point 1: [Seamless Call Transfers Enabled by Real-Time Information Display]

With contract and property information now popping up upon incoming calls, transferring calls to the responsible staff has become significantly smoother.

・Point 2: [New Employees Can Respond Confidently with Visible Tenant, Property, and Room Information]

Even information that is difficult to hear over the phone, such as building or room numbers, can now be confirmed on-screen. This allows less experienced staff to respond confidently, accelerating their proficiency in call handling.

・Point 3: [Significant Increase in Callback Rates Through SMS Usage]

For urgent cases such as water leaks, SMS is used alongside phone calls. Sending approximately 800 SMS messages per month has helped establish a rapid communication system with tenants.

To address industry-wide challenges such as labor shortages and increasing workloads in property management, the company continues to promote the adoption of technology to improve its work environment. Moving forward, Elitz Building Management plans to further enhance customer service quality and create a more supportive workplace through continued use of KaiKura.

Comment from Elitz Building Management Co., Ltd.

Mr. Fujiwara, Department Head, First Management Department: "Our goal is to ensure that every caller receives the same sense of reassurance, regardless of which staff member answers the phone. With customer information displayed upon call arrival and interaction histories recorded and shared after each response, our entire organization can now access the necessary information. This has become a major support in maintaining high-quality service with a limited team."
