The verdict in three sentences
A custom AI support chatbot, connected to your knowledge base via RAG and to your CRM, costs 15,000-55,000 EUR in 2026 depending on scope and guardrails. Done well, it deflects 30-50 % of level-1 tickets and shortens resolution time. ROI is measured on cost per ticket avoided, not on the novelty effect.
Price by solution level
Price depends on the number of knowledge sources, integrations (CRM, ticketing) and guardrail requirements. 2026 order of magnitude.
| Level | Price (EUR) | Scope | Ticket deflection |
|---|---|---|---|
| Essential (FAQ + basic RAG) | 15,000 - 20,000 | 1 source, web widget | 20 - 30 % |
| Standard (RAG + CRM) | 20,000 - 35,000 | Multi-source, CRM, escalation | 30 - 45 % |
| Advanced (multi-channel + guardrails) | 35,000 - 55,000 | Web + WhatsApp, guardrails, analytics | 40 - 50 % |
| Recurring cost | 150 - 600 EUR / month | API tokens + hosting | — |
| Annual maintenance | 15 - 20 % / yr | Updates, re-indexing | — |
Cost vs deflected tickets and savings
The real metric: how much a human-handled ticket costs, and how many the bot absorbs. Based on a level-1 ticket at 6 EUR fully loaded.
| Monthly ticket volume | Deflection 40 % | Tickets deflected | Savings / month |
|---|---|---|---|
| 2,000 tickets | 40 % | 800 | 4,800 EUR |
| 4,000 tickets | 40 % | 1,600 | 9,600 EUR |
| 6,000 tickets | 45 % | 2,700 | 16,200 EUR |
| 10,000 tickets | 45 % | 4,500 | 27,000 EUR |
| 15,000 tickets | 50 % | 7,500 | 45,000 EUR |

Marc, customer service director at a Nantes e-commerce firm, handles 4,000 tickets/month at 6 EUR each. A Standard chatbot at 26,000 EUR with 300 EUR/month in tokens deflects 40 % of tickets — 1,600 tickets and 9,600 EUR/month saved. Net of tokens, the gain exceeds 9,000 EUR/month and the project pays back in under 3 months, while cutting first-response time.
FAQ
Can the bot make up answers? The risk exists but is manageable: RAG forces the bot to rely on your documents, and guardrails block out-of-scope answers by escalating to a human.
Should it integrate with the CRM? Yes for high-value cases: checking an order, a contract or a status. That lifts deflection from 25 % to 40-50 % and improves satisfaction.
How long to deploy? Plan 6 to 12 weeks depending on sources and integrations. A first FAQ + RAG version can go live in 4 weeks.
Can it handle WhatsApp? Yes, adding the WhatsApp channel is common and relevant, especially in markets where it is the primary contact channel.
How is ROI measured? On cost per ticket avoided and reduced handling time. We instrument the bot from launch to track real deflection.
