Customer Service
Customer service is the assistance and advice provided by a company to people who buy or use its products or services, encompassing all interactions before, during, and after a purchase.
In Depth
Customer service is the broadest term encompassing all touchpoints where a company helps its customers. It includes pre-sale support (answering product questions), purchase assistance (helping with checkout or configuration), post-sale support (troubleshooting, returns, warranties), and proactive outreach (informing customers about updates or issues). Modern customer service has evolved from phone-only call centers to omnichannel operations spanning email, chat, social media, messaging apps, and self-service portals.
AI is transforming customer service by automating routine interactions, providing agents with real-time guidance, predicting customer needs before they arise, and enabling 24/7 availability without proportional staffing costs. The shift is from reactive problem-solving to proactive relationship building, where every interaction is an opportunity to strengthen customer loyalty.
