The verdict in three sentences
When a distributor receives 400 requests a day, mostly about stock, reseller prices and warranties, its sales team spends more time answering than selling. An AI assistant on WhatsApp Business at 25,000 to 60,000 EUR, connected to the catalogue and the ERP, handles about 60% of requests with no human involvement. The remaining 40% go to an agent with the context already summarised, for an API cost of 300 to 1,200 EUR a month.
What the assistant handles alone, and what it must escalate
Success depends on scope. An assistant that answers everything makes things up; an assistant limited to verified sources (product sheets, stock, warranty terms, order status) stays reliable.
| Request type | Share of volume | AI handling | Escalation |
|---|---|---|---|
| Availability and stock | 25% | Real-time answer from the ERP | If out of stock and urgent |
| Reseller price and discounts | 18% | Price list based on identified customer tier | Off-list discount |
| Product specifications | 15% | Knowledge base, model comparison | Custom server configuration |
| Order and delivery tracking | 14% | Status, delivery note number, slot | Delivery dispute |
| Warranty and after-sales | 12% | Terms, RMA procedure, ticket | Technical diagnosis |
| Quote request | 10% | Pre-filled quote | Approval by a sales rep |
| Complaints and other | 6% | Acknowledgement | Always a human |
Out of 400 daily requests, the assistant closes about 240 conversations on its own. The other 160 reach an agent with the history, the identified customer and the rephrased question, cutting average handling time from 6 to 3 minutes.
2026 budget: build and recurring costs
| Item | Scope | Range (EUR) |
|---|---|---|
| WhatsApp Business API integration | Approved provider, verified number, message templates | 3,000 to 7,000 |
| Knowledge base | 1,500 to 5,000 product sheets, terms, FAQ | 6,000 to 15,000 |
| ERP connection | Stock, prices, orders via API or export | 7,500 to 18,000 |
| Escalation logic and agent console | Handover, summary, queue | 5,000 to 12,000 |
| Testing, tuning and training | 3 to 4 weeks of tuning on real conversations | 3,500 to 8,000 |
| Total build | 25,000 to 60,000 | |
| Monthly AI API cost | Depends on volume and model | 300 to 1,200 / month |
| WhatsApp conversations | Meta per-message pricing by category | 250 to 900 / month |
| Maintenance and updates | New products, tuning | 900 to 2,200 / month |
API cost mostly depends on conversation length and the chosen model. At 12,000 conversations a month, a fast, well-scoped model stays at the low end of the range. GDPR compliance requires informing customers, limiting conversation retention and documenting the processing in your records, and the EU AI Act requires telling users they are talking to an AI.
Limits to know
The assistant must never quote a price or stock level that does not come straight from the system. Plan also for voice notes, common among resellers: transcription adds 10 to 20% to API cost.
Mini case study
Ciaran, sales director of an IT distributor in Dublin, has 5 agents handling WhatsApp and email at 4,200 EUR a month fully loaded each.
- Before: 400 requests at 6 minutes, so 40 hours a day, all 5 agents saturated.
- After: 160 escalated requests at 3 minutes, so 8 hours a day. Two agents cover support, three move to active selling to resellers.
- Recurring cost: 900 EUR of API, 500 EUR of WhatsApp messages and 1,500 EUR of maintenance, so 2,900 EUR a month.
- Value: 3 redeployed agents represent 12,600 EUR a month of sales capacity, a net gain of about 9,700 EUR a month.

FAQ
Can the assistant get a price wrong?
It only quotes prices read from the ERP at the time of the question. If data is missing, it hands over to an agent; in our tuning, under 2% of answers are corrected after the first month.
How long to launch the assistant?
Count 6 to 10 weeks: 2 weeks for the WhatsApp API and knowledge base, 3 to 4 weeks of integration, then 3 weeks of tuning.
Do customers accept talking to an AI?
Yes when the answer is fast and accurate and a human stays one message away. The rate of agent requests usually falls below 15% after 2 months.
Can we keep the same WhatsApp number?
Yes, the number can move to the WhatsApp Business API, with a few hours of downtime planned outside business hours.
Do we need a specific AI model?
No, the architecture lets you switch provider. The choice rests on language quality, latency and a monthly cost of 300 to 1,200 EUR.
