E-commerce Chatbot Suite
An omnichannel AI chatbot platform handling customer inquiries, order tracking, product recommendations, and returns management across web, mobile, WhatsApp, and Facebook Messenger for a fast-growing online retailer with $28M annual revenue.
The Challenge
StyleHub, a direct-to-consumer fashion retailer, experienced explosive growth from $8M to $28M in annual revenue over 18 months. While sales soared, their customer service infrastructure couldn't keep pace. The numbers painted a dire picture:
Monthly customer inquiries flooding a team of just 8 support agents
Average response time during peak seasons (Black Friday, holidays)
Cart abandonment rate due to unanswered pre-purchase questions
Customer service satisfaction score on Trustpilot
The situation was unsustainable. Key pain points included:
- Repetitive queries eating time: 68% of inquiries were simple questions like "Where's my order?", "What's your return policy?", or "Do you have size M in stock?"
- Channel fragmentation: Customers reached out via email, Instagram DMs, Facebook Messenger, website chat, and phone - no unified system
- Lost sales opportunities: Support team couldn't provide real-time product recommendations during critical decision moments
- Scaling impossible: Hiring more agents wasn't viable - training took 6 weeks and turnover was 45% annually
- Zero coverage nights & weekends: 40% of traffic occurred outside business hours with no support available
The CEO was clear: "We need to solve this without hiring 30 more people. We need AI, and we need it fast."

Client Testimonial
"This AI chatbot suite has been nothing short of transformational for StyleHub. We went from drowning in customer inquiries to having a scalable, 24/7 support system that actually improves conversions. Our human agents can now focus on building relationships with high-value customers instead of answering 'where's my order?' all day. The ROI was positive within 3 months, and we're now handling 3x the customer volume with the same team size. Best investment we've made."
