The verdict in three sentences
An AI lead scoring integration trained on your sales history and connected to your CRM costs between EUR 18,000 and EUR 50,000 in 2026. It predicts each prospect's conversion probability and prioritizes the pipeline, delivering 15-30% higher conversion. Inference cost stays marginal: a few tens of euros a month for thousands of scored leads.
What the budget covers
Price depends on historical data quality, the number of enrichment sources and CRM integration depth. 2026 orders of magnitude for Toronto.
| Item | 2026 range (EUR) | What it includes |
|---|---|---|
| Data audit + score definition | 3,000 - 7,000 | Won/lost history, predictive variables |
| Scoring model + calibration | 6,000 - 16,000 | Training, validation, action thresholds |
| Lead enrichment | 3,000 - 9,000 | Firmographic and behavioural data |
| CRM integration (HubSpot, Salesforce, Pipedrive) | 4,000 - 12,000 | Score fields, automations, alerts |
| QA + team training | 2,000 - 6,000 | Testing, dashboards, sales adoption |
| Project total | 18,000 - 50,000 | Delivered in 6 to 10 weeks |
The monthly inference cost is low: scoring 10,000 leads/month costs EUR 20-100 depending on variable richness. The real recurring cost is model maintenance (quarterly retraining), to budget separately.
The measurable gains
| Metric | Without AI scoring | With AI scoring | Impact |
|---|---|---|---|
| Overall conversion rate | Baseline | +15 to +30% | More sales at constant headcount |

| First-touch delay on priority leads | 24 - 72 h | < 2 h | Speed on the best leads |
| Prioritization accuracy | Gut feel | 75 - 88% (AUC) | Data-driven decisions |
| Inference cost / 10,000 leads | - | EUR 20 - 100 | Marginal |
Mini case study
Thomas, sales director at a B2B SaaS vendor in Toronto, handles 1,800 inbound leads a month for 8 reps. Without prioritization, they work leads randomly; conversion caps at 6%, i.e. 108 sales/month at an average deal of EUR 4,000.
He invests EUR 32,000 in AI scoring connected to HubSpot, delivered in 8 weeks. The model flags the top 25% of leads, worked first within 2 h. Overall conversion rises to 7.4% (+23%), i.e. 133 sales/month. The 25 extra sales represent EUR 100,000 in additional monthly revenue. Even on a cautious net margin, the project pays back in under 2 months and the gain compounds monthly.
