Goal & Outcome
Goal
A fitness app with thousands of daily users faced a critical chargeback problem. Their Ukraine-based support team couldn't respond fast enough to US customers requesting refunds. When responses took 4+ hours due to time zones, frustrated customers filed chargebacks instead of waiting — costing the company lost revenue, processor fees, and potential account restrictions.
Manual 24/7 support wasn't financially viable. The solution needed to check refund eligibility based on usage data, provide policy-compliant responses, and create tickets for human review — all while responding in seconds to prevent chargebacks.
Outcome
We built a production-ready AI support agent that receives tickets from the customer support system via webhooks. The agent uses GPT-4 to analyze requests, syncs deeply with internal backend systems to validate user data, and intelligently escalates complex cases to humans while auto-resolving simple inquiries. We worked closely with the client's support department to crystallize business processes, SOPs, and knowledge base — brainstorming how to handle edge cases and retention scenarios. Our backend development team built an admin panel with conversation monitoring, cost tracking, and prompt management. The system handles thousands of conversations daily at $0.02 per conversation.
How It Works
1.Get Customer Message
AI agent receives tickets via webhooks from the customer support system. Currently email-based, with Instagram and website widget channels planned. Spam is filtered and duplicate tickets are detected automatically.
2.Analyze & Categorize
System categorizes tickets according to company SOPs, sets appropriate tags, and syncs with backend to validate user data (subscription status, usage history). Previous conversation history — even from before AI launch — is loaded for context.
3.Generate Response
GPT-4 generates a response following SOPs and conversation guidelines. If the message contains multiple questions, the agent combines relevant prompts to address each one. Responses are sent in the customer's language.
4.Resolve or Escalate
Simple inquiries are resolved automatically. Cases are escalated to humans when: context is insufficient, actions require approval (refunds, cancellations, discounts), or the customer is frustrated or angry. CRM ticket includes full history and AI recommendation.

What We Built
🔌CRM Webhook Integration
Receives tickets from customer support system via webhooks. Currently email-based, with Instagram and website widget channels planned.
🚨Smart Escalation
AI escalates to humans when context is missing, actions need approval (refunds, discounts, email changes), or customer is frustrated or angry.
🏷️Auto-Categorization
Automatically categorizes and tags tickets based on company SOPs. Detects duplicate tickets and filters spam messages.
💰Retention Flow
Proactively offers trials and discounts to retain customers considering cancellation. Personalized offers based on user history.
⏰Automatic Follow-ups

Automatically detects customer language and responds accordingly while following company policies.
🕐Historical Context
Loads previous conversation history — even from before AI agent launch — to provide context-aware responses.
🔗Deep Backend Sync
Real-time sync with internal systems ensures user data is always present and valid during case processing.
📝Prompt Templates
Manage templates for cancellations, technical issues, feedback, and more with version control support.
📊Token Usage Dashboard
Monitor LLM token consumption, analyze spending, and predict future API costs.
🔒Data Privacy
Sensitive user data is stripped before sending to LLMs, ensuring compliance and security.

FaQ
How much does it cost to build an AI support agent?
AI support agent development costs depend on integration complexity and automation scope. Basic systems range from $20,000 to $50,000, while advanced platforms with CRM integrations and analytics cost $50,000 to $120,000+. Get a free consultation .
What types of customer inquiries can an AI agent handle?
AI agents handle refunds, cancellations, billing, technical issues, account management, and FAQs. They can combine multiple requests, detect duplicates, filter spam, and respond in the customer’s language while following your policies.
How long does it take to build an AI support agent?
Basic AI agents take 2–3 months, while advanced systems with CRM integrations and multi-channel support require 4–6 months. A working prototype is typically delivered within the first month.
Can the AI agent integrate with existing support tools?
Yes, we integrate with email platforms, CRMs, analytics tools, payment systems, and internal backends. Additional channels like website widgets and social media can also be connected.
How do you prevent incorrect or harmful AI responses?
We use policy rules, human review workflows, response testing, confidence thresholds, and continuous monitoring to ensure safe and accurate AI behavior aligned with your guidelines.
What happens if the AI cannot answer a question?
The system escalates to human support when context is missing, approval is required, or the situation is sensitive. Full conversation history and suggested responses are provided to agents.
How much does it cost to run an AI support agent?
Operating costs depend on usage, typically $0.01–$0.05 per conversation. A system handling 10,000 conversations monthly may cost $100–500 in AI usage plus $50–200 for infrastructure.
Can the AI handle multiple languages?
Yes, modern AI models support 50+ languages and can automatically detect and respond in the user’s language while following your business rules.
How is the AI trained on our support policies?
We train AI using your SOPs, historical conversations, escalation rules, and brand voice. Admin tools allow you to update prompts and refine responses without code.
What security measures protect customer data?
We implement encryption, secure APIs, PII masking, GDPR and SOC 2 practices, and regular audits. Customer data is never used to train public AI models.
