The verdict in three sentences
A custom B2B AI support chatbot connected to your knowledge base, WhatsApp and website resolves on average 40% of level-1 tickets with no human involved. For African B2B companies in 2026, budget 6,000,000 to 15,000,000 FCFA (about EUR 9,150 to 22,870) for development and 150,000 to 400,000 FCFA per month (EUR 230 to 610) for API and hosting. Delivery takes 2 to 3 months and the project pays off once you handle more than 300 tickets a week.
Why a generic chatbot falls short in B2B
An internet service provider serving 3,000 businesses does not get the same questions as an online shop. Customers ask about an outage on their fibre link, a copy of an invoice, a bandwidth change, the status of a field intervention. The chatbot must read the customer account, query the ticketing and billing systems, then hand over cleanly to an agent when the question is out of scope.
| Request type | Share of tickets | Solvable by AI | Data required |
|---|---|---|---|
| Status of an ongoing incident | 25% | Yes | Network monitoring tool |
| Invoice copy, balance | 18% | Yes | Billing software |
| Simple technical questions (router, Wi-Fi) | 15% | Mostly | Knowledge base |
| Plan or bandwidth change | 12% | Partly | CRM, plan catalogue |
| Complex outage, field visit | 20% | No, agent handover | Ticket pre-qualified by AI |
| Complaint, commercial dispute | 10% | No, agent handover | Customer history |
In practice, the chatbot closes about 40% of tickets on its own and pre-qualifies the rest, saving the agent 3 to 5 minutes on every handover.
2026 prices in Dakar, by project level
| Level | Scope | Development price | Monthly cost (API + hosting) | Timeline |
|---|---|---|---|---|
| Essential | Smart FAQ on the website, knowledge base | 6,000,000 FCFA | 150,000 FCFA | 6 to 8 weeks |
| Standard | Website + WhatsApp Business, account lookup, agent handover | 9,500,000 FCFA | 250,000 FCFA | 8 to 10 weeks |
| Advanced | Standard + ticket creation, invoices, real-time incident status | 12,500,000 FCFA | 320,000 FCFA | 10 to 12 weeks |
| Enterprise | Advanced + Wolof and French, voice, quality dashboard | 15,000,000 FCFA | 400,000 FCFA | 12 weeks |
API cost depends on conversation volume and the model used. For 3,600 conversations a month with 8 exchanges each on average, the language model budget sits around 80,000 to 150,000 FCFA, the rest covering hosting, the vector database and WhatsApp Business fees (2026 order of magnitude).
What the project includes
- Knowledge base: your procedures, technical guides and terms, structured and kept up to date by your team through a back office.
- Channels: widget on the website and customer portal, verified WhatsApp Business number.
- Integrations: CRM, ticketing, billing, network monitoring, via API.
- Agent handover: switching rules (detected frustration, out-of-scope request, key account), with a conversation summary passed to the agent.
- Monitoring: resolution rate, satisfaction, emerging topics, conversations to review.
- Security: customer authentication before any sensitive data, compliance with Senegal's data protection law 2008-12 and declaration to the CDP.
Mini case study
Moussa, head of customer service at an internet provider in Dakar, handles 3,000 business customers and 900 tickets a week with 14 agents. One agent processes about 65 tickets a week at a loaded cost of 450,000 FCFA a month.
- Tickets resolved by AI: 40% x 900 = 360 tickets a week
- Agent capacity freed: 360 / 65 = 5.5 agents
- Potential saving: 5.5 x 450,000 = 2,475,000 FCFA a month
- Advanced chatbot cost: 12,500,000 FCFA + 320,000 FCFA a month
- Net monthly gain: about 2,155,000 FCFA, payback in 6 months

FAQ
Can the chatbot answer in Wolof?
Yes, at the Enterprise level. Language models handle everyday written Wolof well in 2026, with about 85% comprehension after tuning on your real conversations.
What if the AI gives a wrong answer?
The chatbot answers only from your knowledge base and cites its source. Below a confidence threshold, it hands over to an agent. Risky conversations are reviewed weekly, about 2 hours of work.
How much does WhatsApp Business add?
Service conversations opened by the customer are free within the 24-hour window. Template messages sent by the business cost a few dozen FCFA each.
Can we update the answers ourselves?
Yes, a back office lets you add or edit an article in minutes. The AI picks up the change within 5 minutes.
Do we need to change our ticketing tool?
No. We connect to your existing tool (Zendesk, Freshdesk, GLPI or in-house) via API. A tool without an API needs 1 to 2 extra weeks of development.
Let's scope your project. Share your ticket volume, channels and current tools: we will price a chatbot between 6,000,000 and 15,000,000 FCFA, delivered in 2 to 3 months. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
