In today's competitive business environment, reducing customer service costs is not only desirable but also essential for businesses to maintain profitability and achieve sustainable growth. Many companies are seeking smart solutions to cut operational expenses while still ensuring excellent customer service quality.

Why is it necessary to optimize customer service costs?
Customer service costs often account for a significant portion of a company's total operating budget. According to research by Bellsystem24 Vietnam, companies can save 20-40% of their costs by implementing appropriate optimization strategies. Saving on customer service costs does not mean reducing service quality, but rather finding more efficient ways to serve customers.
Common challenges in cost management
Businesses often face challenges such as high personnel costs, costly technology investments, and difficulties in measuring the ROI of customer care activities. In particular, with the growth of e-commerce and increasingly high expectations from customers, cost pressures are becoming even greater.
Where should you start to optimize costs?
To answer this question, analyze the cost structure of the customer service department. Below are five common cost categories.
1. Personnel expenses (~60-70%)
This is the cost category with the highest proportion. It includes:
- Base salary for Customer Service Representatives, Team Leaders, QA...
- Insurance costs, bonuses, benefits
-
Recruitment costs, initial and periodic training
This cost category can be fixed or fluctuate up or down depending on the company's usage needs.
2. Technology system (~5-10%)
- Call Center (PBX/IP-PBX/Cloud Call Center)
- Customer Relationship Management (CRM), Ticketing system
- Chat software, chatbot, email routing
- System integration costs (API, CRM, ERP)
3. Telecommunications costs (~5-10%)
Primarily with voice channels (outbound/inbound calls). For large customer service centers, domestic voice charges are significant if call volume is high.
Include:
- Telephone call charges (outbound & inbound)
- Rent a prefix (1800, 1900, SIP number)
- Internet bandwidth, IP Phone
4. Infrastructure & Facilities (~5-10%)
Include:
- Lease space (if in-house)
- Equipment: computer, headphones, desk and chair
- Electricity, water, maintenance, office supplies
5. Quality Management & Improvement (~5%)
Include:
- Recruitment costs
- Customer Satisfaction Survey (CSAT, NPS)
- Call data analysis tool, QA automation
- E-learning software, internal training
Based on the above cost groups, we can easily see the group Personnel costs are the group with the highest proportion of expenses. (60-70%) and this is also the group that needs to be optimized. However, unlike unplanned cuts, businesses need to strive to improve the performance of call center agents by providing them with knowledge platforms, support tools, and structured work processes to help them increase their efficiency. As a result, a call center agent can achieve 2-3 times the productivity, helping the business reduce personnel costs by hiring fewer people while still ensuring quality work.
Cost-saving strategies that are effective while still ensuring quality
1. Implement smart technology

Instead of completely replacing employees, chatbot It should be designed as the first line of defense. The AI system can handle 65-75% frequently asked questions such as order checks, basic product information, and usage instructions. When encountering complex questions, the system will seamlessly transfer them to specialized staff, along with all the information provided by the customer.

Smart CRM integration
CRM System Modern systems not only store customer information but also predict needs and suggest solutions. This helps employees process requests 40% faster than traditional methods, while also personalizing the customer experience.

Analyze each step in the customer service process in detail to eliminate non-value-adding activities. Standardizing the process helps reduce average processing time by 25-35 minutes without compromising service quality.

Self-service customer portal

Video tutorials and interactive guides

Real-time coaching
Provide suggestions and guidance to employees while interacting with customers through an AI assistant, helping to improve call quality and reduce processing time.
Balancing cost savings and service quality
The principle of "Quality First, Cost Second"
Many businesses make the mistake of trying to cut costs at all costs while forgetting the importance of quality.

Research shows that the cost of retaining an existing customer is only one-fifth of the cost of finding a new customer.
