|---|---|---|
| Answers | Only predefined flows | Free conversation |
| Training | Weeks of intent mapping | Hours with documents |
| Flexibility | Rigid, only exact matches | Understands variations |
| Maintenance | Constant updates needed | Self-learning |
| User Experience | Frustrating | Natural |

| Vector DB | €0-€50 |
| Chat Tool | €50-€200 |
| Total | €100-€750/month |
ROI Calculation (Example)
Assumptions:
- 500 support inquiries/month
- 50% answered by bot
- €15 cost per manual inquiry
Savings:
- 250 × €15 = €3,750/month
- Minus costs: €500/month
- Net savings: €3,250/month
Payback: At €15,000 implementation = 5 months
Avoiding Common Mistakes
Mistake 1: Wanting Too Much at Once
Problem: The bot should do everything.
Solution: Start with one use case. Expand after success.
Mistake 2: Poor Knowledge Base
Problem: Bot answers incorrectly or knows nothing.
Solution: Invest in clean, current documentation. Garbage in = Garbage out.
Mistake 3: No Human Handoff
Problem: Users get stuck, can't escalate.
Solution: Always build a path to humans. "Would you like to speak with a team member?"
Mistake 4: No Personality
Problem: Bot sounds robotic and impersonal.
Solution: Define tone of voice. Give the bot a name and character.
Mistake 5: Not Measuring
Problem: No idea if the bot works.
Solution: Track: Conversations, resolution rate, handoffs, CSAT.
