The Problem
An e-commerce company with 12 support staff handles 200 customer inquiries a day. The analysis shows: 80% of them are standard inquiries — order status, returns, delivery times, tracking links. Yet every ticket is handled manually.
The result: average response time of 36 hours. Customer satisfaction at 78%. The support team is overloaded with repetitive work while complex requests wait. Annual support costs: around 50,000 euros.
- 200 tickets/day — 160 of them (80%) standard inquiries
- 36h average response time — customers wait almost two days
- 3 FTE fully tied up with repetitive standard inquiries
- 78% customer satisfaction — below average for the industry
The Solution
A three-part chain of AI agents that processes the entire ticket intake:
- Classifier agent: Analyzes every incoming ticket and classifies it into categories (order status, return, payment, complaint, other). Decides: auto-response possible or human escalation needed?
- Responder agent: Generates a personalized reply for classified standard inquiries — including pulling order status via API, automatic tracking-link generation and on-brand wording.
- Escalator agent: Complex tickets (complaints, return exceptions, payment disputes) are forwarded with full context to the responsible human agent.
Technical stack: Claude API for classification and reply generation, Python for orchestration, webhook integration with the existing ticketing system, Firestore for the audit log.
Results
| Metric | Before | After | Improvement |
|---|---|---|---|
| Automation rate | 0% | 70% | +70 percentage points |
| Avg. response time | 36 hours | 2 hours | 94% faster |
| Support costs/month | €4,167 | €2,083 | 50% less |
| Customer satisfaction | 78% | 91% | +13 percentage points |
| Capacity freed up | — | 140 hrs/month | for higher-value work |
Implementation Timeline
- Week 1Set up API access, analyze the last 3 months of ticket data, define categories
- Week 2–3Build and test the classifier and responder agents — initially on historical tickets without live deployment
- Week 4Soft launch: 20% of incoming tickets run through the system. Agents output suggestions, humans approve them at first
- Week 5–6Monitoring, error analysis, prompt optimization. Error rate drops from 30% to under 5%
- Week 7Full rollout: 70% of tickets are answered fully automatically
Learnings & Best Practices
- Human-in-the-loop at the start: For the first two weeks of the soft launch, every AI reply was reviewed by a human. That built trust and allowed targeted corrections.
- Iteration is decisive: The first week had a 30% error rate (wrong categorization, imprecise answers). After targeted prompt optimization the rate dropped below 5%.
- Clear escalation rules: Every ticket that contains a complaint always goes to a human — no exceptions. That protects the customer relationship.
- Transparency toward customers: In the reply footer line: "This response was created with AI assistance. Questions? Just reply to this email." — customers respond positively to transparency.
The automation didn't replace jobs — it freed the team from 160 repetitive tasks a day. The time freed up flows into nurturing customer relationships and improving the product.
