The verdict in three sentences
A B2B customer-support AI agent runs 18,000 to 45,000 EUR (excl. VAT) in 2026 in Berlin, excluding token usage (300 to 2,000 EUR/month depending on traffic). The real gain comes from deflecting 30 to 50% of level-1 tickets, provided you have serious RAG over your documents and flawless human escalation. Budget 2 to 4 months, with a month of calibration before opening the agent to 100% of traffic.
What drives the price
A scripted chatbot is cheap and disappoints. An agent that answers correctly on YOUR contracts, YOUR specs and YOUR procedures needs RAG engineering, guardrails and supervision.
| Tier | Scope | Connected sources | 2026 budget (EUR excl. VAT) | Timeline |
|---|---|---|---|---|
| Pilot | 1 channel, dynamic FAQ | 1 base (product docs) | 18,000 - 25,000 | 2 months |
| Standard | 2-3 channels, RAG + escalation | 2-4 bases (docs, CRM, tickets) | 25,000 - 35,000 | 3 months |
| Advanced | Multi-channel, actions (API) | 5+ sources + tooling | 35,000 - 45,000 | 4 months |
| Bespoke | Multilingual, multi-brand | Unlimited + fine-tuning | 45,000 + | 4 months + |
Token cost depends on model and volume. 2026 order of magnitude: 0.02 to 0.08 EUR per resolved conversation, usually far below a human ticket.
The real math: cost per ticket
The question isn't "what does AI cost" but "what does a ticket cost before and after".
| Metric | 100% human support | With AI agent |
|---|---|---|
| Average L1 ticket cost | 6 - 12 EUR | 0.05 - 1 EUR (auto) |
| First response time | 2 - 24 h | < 30 s |
| L1 resolution rate without human | 0% | 30 - 50% |
| Availability | Office hours | 24/7 |
| Satisfaction (well built) | Baseline | + 5 to 10 pts with smooth escalation |
The key: an agent that knows how to say "I'll hand over" and passes full context to the advisor. Without that escalation, deflection becomes frustration.

Mini case study
Mehdi runs customer support at a B2B SaaS vendor in Berlin: 4,500 tickets/month, of which 55% are level 1 (how-to, where-to-find, resets). Average ticket cost: 8 EUR (excl. VAT). He deploys a Standard agent at 31,000 EUR. The agent deflects 40% of L1, i.e. ~990 tickets/month absorbed, at a token cost of ~700 EUR/month. Gross saving: 990 x 8 = 7,920 EUR/month, minus 700 = ~7,200 EUR/month net. Payback in about 4.5 months, and his advisors finally focus on high-value cases.
FAQ
Can the agent make up answers? Hallucination risk is reduced by RAG (the agent cites your documents) and by guardrails that refuse out-of-scope questions. We measure the unsourced-answer rate and keep it under 2%.
How does escalation to a human work? The agent detects uncertainty or sensitive requests, opens a ticket with full history and routes to the right queue. The advisor resumes without making the customer repeat anything.
How much are tokens per month? 2026 order of magnitude: 300 to 2,000 EUR depending on volume and chosen model. We optimise with caching and model choice per question type.
Can it act, not just answer? Yes, with API actions (open a ticket, check an order status, resend an invoice), which pushes the budget toward the Advanced tier.
How fast do we see deflection? From month one, but the 30-50% target is reached after 4 to 6 weeks of calibration on your real tickets.
