The verdict in three sentences
For a software publisher or services firm in Singapore receiving more than 150 website enquiries per month, an AI lead qualification chatbot pays for itself as soon as your sales reps stop calling back contacts with no budget and no project. The choice is between a SaaS tool at EUR 50 to 500 per month and a custom chatbot at EUR 3,810 to 6,100 excl. VAT (2.5 to 4 M FCFA), connected to your CRM and your scoring rules. Plan 4 to 6 weeks of project time and a usage cost of EUR 0.01 to 0.05 per conversation, a few dozen euros per month at SME volume.
Why your forms let in too much noise
A standard contact form collects a name, an email and a free-text message. The rep then has to call back to find out whether the prospect has a budget, a deadline and decision power. On a typical B2B inbound flow in 2026, a significant share of requests falls outside the target: students, job applicants, suppliers, very small businesses outside the offer. Each pointless callback costs 15 to 25 minutes of sales time.
The chatbot asks qualification questions when interest is at its peak, assigns a score, then routes: immediate meeting booking for hot leads, content or nurturing for the rest. The rep receives an already completed record in the CRM.
| Journey step | Chatbot question or action | Data sent to the CRM | Expected effect |
|---|---|---|---|
| Identification | Industry, company size, job title | Company and contact fields | Exclude off-target profiles |
| Need | Problem to solve, current solution | Need field + AI summary | Prepare the discovery call |
| Budget | Expected range (4 brackets) | Budget field | Filter requests below the threshold |
| Timing | Desired start (under 3 months, 3 to 6, later) | Timing field | Prioritise near-term projects |
| Decision | Role in the decision, other stakeholders | Authority field | Identify the real sponsor |
| Scoring | Automatic score out of 100 | Score + lead status | Hot, warm, cold routing |
| Meeting | Slot offered in the rep's calendar | Calendar event + video link | Shorten time to first contact |
SaaS or custom: the 2026 figures
SaaS tools (conversational widgets built into a CRM or standalone tools) deploy fast, but their scoring logic stays generic and the bill grows with conversations or seats. A custom build requires an upfront investment, but it follows your exact qualification grid, your offers and your tone, and runs on a language model API billed per use.
| Criterion | Conversational SaaS tool | Kolonell custom chatbot |
|---|---|---|
| Upfront cost | EUR 0 to 1,500 of setup | EUR 3,810 to 6,100 excl. VAT (2.5 to 4 M FCFA) |
| Monthly cost | EUR 50 to 500 depending on volume and seats | EUR 0.01 to 0.05 of API per conversation + hosting |
| Maintenance | Included in the subscription | 35,000 to 120,000 FCFA per month (EUR 50 to 180) depending on plan |
| Scoring | Simple rules, fixed fields | Custom grid, adjustable weights |
| CRM integration | Limited native connectors | HubSpot, Salesforce, Pipedrive or in-house CRM API |
| Go-live time | 1 to 2 weeks | 4 to 6 weeks |
| Data ownership | Hosted by the vendor | Database and prompts belong to you |
Over 3 years, a SaaS tool at EUR 300 per month adds up to EUR 10,800. A custom build at EUR 5,000 excl. VAT, plus EUR 110 of Standard maintenance and about EUR 30 of API per month, comes to roughly EUR 10,040, with a scoring grid you own. Below EUR 100 per month of SaaS, the standard tool remains cheaper.
What the project really includes
A serious project runs in four work packages: a qualification workshop with the sales team (criteria and thresholds), design of the conversation flow and guardrails (the bot never promises prices or deadlines), CRM and calendar integration, then a 2-week test phase with conversation reviews. Singapore's PDPA requires clear notice, a defined retention period and the option to reach a human at any time.
| Work package | Indicative duration | Deliverable |
|---|---|---|
| Qualification workshop | 1 week | 100-point scoring grid, routing thresholds |
| Flow and prompts | 1 to 2 weeks | Conversation tree, validated answer base |
| Integrations | 1 to 2 weeks | CRM, calendar, Slack or email notifications |
| Testing and tuning | 1 week | Review report on 50 conversations, adjustments |
| Follow-up | Ongoing | Dashboard of qualification and meeting rates |
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Daniel, sales director of an HR software publisher in Singapore, receives 200 enquiries per month through his website. His two reps call every contact back, at 20 minutes per call: 66 hours per month. He estimates that about 60% of these requests are off-target. With a chatbot that filters and routes, only 80 qualified requests remain, or 27 hours. The saving is about 39 hours per month. Valued at EUR 45 per loaded hour, that is EUR 1,755 per month. For a EUR 5,000 project plus EUR 140 of monthly costs, payback comes in just over 3 months, according to this estimate.
FAQ
How much does a B2B AI qualification chatbot cost in 2026?
A SaaS tool costs EUR 50 to 500 per month depending on volume. A Kolonell custom chatbot ranges from EUR 3,810 to 6,100 excl. VAT (2.5 to 4 M FCFA), with an API cost of EUR 0.01 to 0.05 per conversation.
Can the chatbot fill our CRM directly?
Yes, it creates or updates the contact and company record with the score, budget and timing. Common integrations (HubSpot, Salesforce, Pipedrive) take 1 to 2 weeks within the 4 to 6 week schedule.
How do we stop the AI from making up answers?
The bot answers only from a validated content base and hands over to a human as soon as a question goes out of scope. Reviewing at least 50 conversations before launch helps correct deviations.
Is it compliant with data protection rules?
Yes, if user notice is clear, the retention period is set (for example 3 years for a prospect) and data goes through an API provider committed to no reuse. These points are written into the specifications.
What minimum volume justifies a custom build?
Below 80 to 100 enquiries per month, a SaaS tool under EUR 100 per month is usually enough. Above 150 enquiries or with specific scoring, a custom build makes sense.
