  • Natural Conversation: GPT-4, Claude can communicate fluently
  • Context Understanding: RAG (Retrieval Augmented Generation) enables company-specific knowledge
  • Easy Integration: APIs and no-code tools make implementation fast
  • Falling Costs: API prices are dropping, efficiency is rising

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.
