It provides comprehensive customer care on a unified platform, increasing response times. It offers support and answers questions anytime, anywhere. This enhances the service experience at every “touchpoint” with the brand, significantly boosting revenue for the business.

What types of phone numbers are used as hotlines for multi-channel customer service?

– Mobile numbers: These are popular numbers trusted by most SMEs and small businesses, due to their convenience, ease of deployment, and cost-effective monthly subscription fees. Examples: 038x xxx xxx,…

– Fixed-line numbers: These are phone numbers used within a province or city. With area codes such as: 0274 – Binh Duong, 028 – Ho Chi Minh City, and 024 – Hanoi. Its advantage is the simple registration process, creating high credibility and trust with recipients for the brand.

The call rate ranges from 1,000 VND/minute to 8,000 VND/minute. Example: 1900 79 xx xx.

Customer Care with OmniChannel Contact Center

An omnichannel contact center is a solution that unifies all communication channels such as phone calls, SMS marketing, Facebook Messenger, email, Zalo, etc. So how can you effectively care for customers using only one software?

Information Consolidation

Customers can come from many different sources, and you can’t divide them into separate channels for management. This wastes time and doesn’t yield effective results. Therefore, with an intelligent omnichannel contact center, you can consolidate all information into a single software. This ensures that sales/telesales can conveniently control data.

Customer Identification

The integrated CRM-mini feature identifies each customer directly on the interface. The omnichannel contact center helps staff quickly grasp all information through call pop-ups. Conveniently store and update basic information, interaction history, and transaction confirmations.

Quickly address feedback through the Ticket feature.

Making customers happy from arrival to departure isn’t just about offering attractive loyalty programs and promotions. It’s also about the speed at which customers receive responses to their inquiries from the business. A delay of even a second means you’re giving a sales opportunity to a competitor.

The Ticket feature is for receiving, distributing, processing, tracking, and reporting the progress of work by relevant departments/divisions. It also facilitates easy management of interactions between employees and customers.

Satisfaction Survey

To improve service quality, you can’t ignore customer satisfaction surveys. It helps businesses identify weaknesses to address and strengths to further develop. The survey will be conducted after the call ends. The Omnichannel Contact Center system automatically sends SMS marketing messages, emails, Zalo messages, etc., to record customer feedback.
