AI Chatbots and Voice Assistants for Commerce Customer Service

Klarna, the Swedish buy-now-pay-later financial services company, launched an AI assistant powered by large language model technology in early 2024. According to data reported by OpenAI, the assistant handled 2.3 million conversations in its first month, managing two-thirds of all customer service chats and performing the equivalent work of 700 full-time agents. Resolution times dropped from 11 minutes to less than two minutes, and the company projected a $40 million profit improvement for 2024. However, by 2025, Klarna reversed course and began rehiring human agents after acknowledging that an overemphasis on cost reduction had led to lower service quality, as reported by CX Dive in May 2025. The company now operates a hybrid model where AI handles routine inquiries while human agents address complex and sensitive cases, illustrating both the potential and the limitations of AI-first customer service strategies.

In the retail sector, a Gartner case study documented how Solo Brands, a direct-to-consumer outdoor lifestyle retailer, deployed a generative AI chatbot that increased its resolution rate from 40% to 75% of customer interactions while improving satisfaction scores and reducing escalations. Separately, a global apparel retailer implemented an AI-powered chat agent across its website and mobile app in more than 15 languages, reducing operational costs by an estimated 30% annually while maintaining 24/7 availability. In financial services, Bank of America reported in February 2025 that approximately 20 million clients had used Erica, the institution's AI virtual assistant, with 676 million interactions in 2024 alone and more than 2.5 billion total interactions since launch in 2018.
