The verdict in three sentences
When 30% of inbound enquiries are off-target, your sales reps spend a day a week sorting instead of selling. An AI lead qualification assistant built into the website costs 6,000 to 18,000 EUR excluding VAT, plus 50 to 400 EUR a month in usage, asks the right questions, computes a score and hands hot leads to a rep in under 5 minutes. Since August 2026, the EU AI Act requires visitors to be clearly told they are talking to an AI: easy to comply with, but it must be in the specification.
What a poorly qualified lead costs
For an office furniture manufacturer selling to companies with 20 to 500 workstations, an unqualified enquiry costs sales time and delays good deals. The figures below are a 2026 order of magnitude for 200 enquiries a month.
| Indicator | Without AI assistant | With AI assistant | Difference |
|---|---|---|---|
| Enquiries received per month | 200 | 200 | = |
| Off-target enquiries handled by a rep | 60 | 8 to 12 | 50 avoided |
| Sorting time per enquiry | 15 to 20 min | 2 to 3 min (reading the summary) | 80% less time |
| Time to first contact on a hot lead | 4 to 24 h | under 5 min | Decisive responsiveness |
| Information collected before the call | Name, email, free text | Headcount, floor area, budget, deadline, city | Better prepared call |
| Out-of-hours enquiries handled same day | 0% | 100% (qualification) | No lead left waiting |
The clearest gain comes from response time: on an office fit-out tender, the supplier who calls back within the hour often wins the site visit.
What an AI qualification assistant costs in 2026
| Item | 2026 range | What drives the price |
|---|---|---|
| Conversation flow and scoring rules | 1,500 to 4,000 EUR | Number of segments (SMEs, key accounts, public sector) |
| Assistant development and website integration | 3,000 to 8,000 EUR | Simple widget or full conversational form |
| CRM connection (HubSpot, Pipedrive, Salesforce) | 1,000 to 4,000 EUR | Standard API or customised CRM |
| Knowledge base (catalogue, lead times, regions) | 500 to 2,000 EUR | Number of product sheets and documents |
| Total project | 6,000 to 18,000 EUR | Scope above |
| AI model usage | 50 to 400 EUR a month | Number of conversations and their length |
| Kolonell maintenance | 50, 110 or 180 EUR a month | Basic, Standard or Premium plan |
At Kolonell, this kind of assistant is a simple to medium application: 3,810 to 6,100 EUR (2,500,000 to 4,000,000 FCFA) for a single flow connected to a standard CRM, 6,100 to 10,670 EUR (4,000,000 to 7,000,000 FCFA) with several segments, regional routing and a dashboard.
Scoring rules that work in B2B
- Headcount or workstations: under 10, redirect to the online shop.
- Project deadline: under 3 months, immediate handover to a rep.
- Stated budget: threshold agreed with sales management, for example 15,000 EUR.
- Region: Berlin and Brandenburg handled directly, rest of Germany routed to dealers.
- Contact role: facilities, management or procurement, each with a tailored message.
AI Act and GDPR: obligations to build in
A qualification assistant is not a high-risk system, but Article 50 of the AI Act imposes transparency: the visitor must know they are talking to an AI. Add a clear notice in the chat window, an option to request a human, and on the GDPR side information on purpose, retention period (often 3 years for a prospect) and where conversations are hosted.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Illustrative persona: Jonas, sales director of an office furniture manufacturer near Berlin, 6 reps. Out of 200 monthly enquiries, 60 are off-target and cost 18 minutes each, or 18 hours a month. The assistant filters out 50: 15 sales hours freed per month, 180 hours a year. At 60 EUR per loaded hour, that is 10,800 EUR a year. If the under-5-minute response wins just 2 extra deals of 25,000 EUR at 30% margin, the gain reaches 15,000 EUR. For a 12,000 EUR project and 150 EUR monthly usage, payback comes in under a year.
FAQ
Does the AI assistant replace the contact form?
It complements it. Keep a classic form for visitors who prefer to write: in practice, 60 to 70% of enquiries go through the assistant once it is well placed.
Can the AI invent lead times or prices?
The risk exists if the assistant is not constrained. It is limited to a validated knowledge base and forbidden from giving firm prices: it passes on the enquiry with a summary.
How long until go-live?
Plan 4 to 8 weeks: 2 weeks of scoring design, 2 to 4 weeks of development, then 2 weeks of testing with the sales team.
What does the AI Act say about this kind of tool?
It is a transparency obligation, applicable since 2 August 2026: tell users they are talking to an AI. Fines can reach 15 million euros or 3% of global turnover, but compliance comes down to a notice and a human contact button.
Can usage costs spiral?
Not if conversation length is capped. For 200 to 400 conversations a month, the bill usually stays under 150 EUR.
