What Is a Phone Answering Service?
A phone answering service is an outsourced service that handles initial phone responses on behalf of businesses and sole proprietors. The basic model involves operators answering incoming calls, taking messages, and reporting via email or chat. According to MIC's Communications Usage Trend Survey, approximately 35% of SMEs cite phone handling burden as a management challenge, and the phone answering service market has reached approximately 30 billion yen annually.
The growing attention on phone answering services is driven by labor shortages and diversifying work styles. For companies with 10 or fewer employees, the cost of keeping administrative staff on-site solely for phone handling strains the business. Implementing a phone answering service at around 10,000 yen per month secures phone coverage at less than one-tenth of personnel costs, freeing staff to focus on core business. Choosing the right business phone can also help optimize your phone environment.
Types of Phone Answering Services
Secretary Service Type
The most common type, where a dedicated operator answers calls using your company name. Primary duties include taking messages, arranging callbacks, and answering simple questions. Standard plans cost 5,000 to 15,000 yen per month and include 50 to 100 calls. Excess calls are charged at 150 to 300 yen per call.
The strength of secretary-type services is that human operators handle calls, so customers are less likely to feel "passed around." This is particularly effective in industries where first phone impressions directly impact conversion rates, such as professional services (lawyers, accountants) and real estate.
Call Center Type
This type handles more advanced tasks such as order processing, appointment management, and complaint resolution. Beyond scripted responses, operators with product knowledge answer customer questions. Costing 30,000 to 100,000 yen per month - more than secretary types - the advantage is integrating phone handling directly into business processes. Common applications include e-commerce order intake, clinic appointment management, and repair request desks.
IVR (Interactive Voice Response) Type
Instead of human operators, automated voice guidance routes calls. "For inquiries about X, press 1; for Y, press 2" voice prompts classify the purpose and transfer to the appropriate person. At 3,000 to 10,000 yen per month, this is the most affordable option, though some customers may find the mechanical interaction unsatisfying. It is well-suited for after-hours initial response and efficiently routing high call volumes. Understand the differences between toll-free and Navi Dial numbers to choose the right number range to pair with IVR.
AI Phone Response Type
The latest services use speech recognition and natural language processing to handle calls with near-human dialogue. They can automate responses to routine questions, appointment booking, and callback arrangements. Available 24/7, these services cost 10,000 to 50,000 yen per month. However, they have limitations with complex consultations and emotional complaints, making a hybrid approach with human operators more practical.
Comparing Pricing Models
Phone answering service pricing falls into three main categories. Accurately assess your incoming call volume to choose the most cost-effective plan.
- Fixed monthly fee: Flat rate up to a set number of calls per month. Best for companies with stable call volumes. Watch for high per-call overage charges
- Pay-per-call: Fully usage-based at a set rate per call. Best for companies with low or highly variable call volumes. Typical rates are 200 to 500 yen per call
- Hybrid: Base fee plus per-call overage charges. The most common model, balancing cost predictability with flexibility
Industry-Specific Use Cases
Professional Services (Lawyers, Accountants, Labor Consultants)
For professional services, the phone is a lifeline for new client acquisition. Industry research shows that when a prospective client's first call goes to voicemail, approximately 70% will call another firm instead. A phone answering service ensures calls are answered during meetings or while out of the office, capturing the caller's contact information and purpose. An investment of 8,000 to 12,000 yen per month pays for itself if it prevents even one missed new consultation.
Real Estate
This industry frequently faces situations where agents cannot answer calls during property viewings or contract procedures. In rental brokerage especially, the speed from inquiry to viewing appointment determines conversion rates. Having an answering service handle initial calls - capturing property names and preferences - enables targeted proposals when returning calls.
E-Commerce
Order confirmations, shipping status inquiries, and return/exchange requests generate high volumes of routine phone interactions. Outsourcing FAQ-based responses to a call center-type service frees internal staff for product development and marketing. Choosing a service that allows spot staffing increases during peak periods (year-end, sale events) further improves cost efficiency.
Sole Proprietors and Freelancers
When running a business solo, phone interruptions during focused work significantly reduce productivity. For programmers, designers, writers, and other concentration-intensive roles, having an answering service handle initial calls and batching callbacks is effective. A secretary-type service at around 5,000 yen per month is sufficient, and combined with a virtual phone number, you can maintain a business contact point without exposing your home number.
Selection Checklist
When choosing a phone answering service, evaluate the following factors comprehensively - not just price.
- Operating hours: Weekdays 9-18 only, or weekends/holidays/evenings too? Some industries require 24/7 coverage
- Reporting method: Does it support the tools you already use - email, Slack, Chatwork, LINE?
- Response quality: Check operator training programs, answer rate (percentage of calls answered), and average response time. Target 95% or higher answer rate
- Customizability: Can you modify response scripts, add answers to specific questions, or set up VIP customer priority handling?
- Security: Verify personal data handling practices and certifications like Privacy Mark or ISMS
- Contract terms: Check for minimum contract periods. Month-to-month cancellation is preferable
Implementation Pitfalls
Several pitfalls require attention when implementing a phone answering service.
First, inadequate response scripts leave operators unable to handle calls properly, potentially increasing customer frustration. Before launch, identify expected inquiry patterns and prepare response templates. Scripts should be regularly reviewed and updated based on actual inquiry content.
Second, don't leave everything to the answering service - maintain fast callback response times. The answering service handles initial contact only; final customer resolution remains your responsibility. Establish rules like "return calls within 30 minutes of receiving a report" and build internal operational processes accordingly.
From a phone number privacy management perspective, it is also important to define in advance the scope of information shared with the answering service. Execute a non-disclosure agreement (NDA) with the provider regarding customer data handling.
Thinking About ROI
Evaluate phone answering service ROI by comparing "opportunity cost of missed calls" against "monthly service fee."
For example, suppose a company that was missing 5 out of 20 monthly calls implements a 10,000 yen per month answering service. If even one of those 5 previously missed calls converts, the monthly fee is recovered in most industries. For professional services, a single consultation fee (5,000 to 10,000 yen) covers it; for real estate brokerage, a single commission (tens of thousands to hundreds of thousands of yen) more than justifies the cost.
Conversely, if call volume is extremely low (under 10 per month) or phone inquiries rarely occur in your industry, voicemail plus callbacks may suffice. Recording your incoming call data for one month before deciding is the prudent approach.
