The verdict in three sentences
In 2026, an SME deploying a single, well-scoped AI use case spends 5,000-15,000 EUR on a POC and 15,000-70,000 EUR to reach production. Recurring API token cost runs 100-800 EUR/month depending on volume, plus hosting and maintenance. Profitability comes from a narrow, measurable scope, not a generic AI meant to do everything.
What each use case costs in production
Price depends on use-case complexity, depth of integration into your systems, and required guardrails. 2026 order of magnitude for a European SME.
| AI use case | POC (EUR) | Production (EUR) | API tokens / month |
|---|---|---|---|
| Inbound email triage & routing | 5,000 - 8,000 | 15,000 - 25,000 | 100 - 300 EUR |
| Automatic meeting summaries | 5,000 - 9,000 | 16,000 - 28,000 | 150 - 400 EUR |
| Document data extraction | 7,000 - 12,000 | 20,000 - 45,000 | 200 - 600 EUR |
| Churn prediction / lead scoring | 8,000 - 15,000 | 30,000 - 70,000 | 150 - 500 EUR |
| Internal assistant (RAG on docs) | 8,000 - 14,000 | 25,000 - 55,000 | 300 - 800 EUR |
Where the budget goes
An AI project is not just an API call: most of the cost is the engineering around the model. Typical split for a 2026 production build.
| Item | Share of budget | What it covers |
|---|---|---|
| Scoping and data | 15 - 20 % | Success definition, data quality and access |
| Development and integration | 40 - 50 % | Prompts, RAG, system connectors, UI |
| Guardrails and evaluation | 15 - 20 % | Tests, eval sets, hallucination reduction |
| GDPR compliance | 5 - 10 % | Anonymization, data localization, register |
| Annual maintenance | 15 - 20 % / yr | Model updates, monitoring, tuning |

Claire, CFO of an industrial SME in Lyon (85 staff), receives 400 customer emails a day in one shared inbox. AI triage with automatic routing costs 22,000 EUR in production and 220 EUR/month in tokens. It saves 1.5 h/day for two assistants — roughly 3 h/day valued at 40 EUR, or 2,400 EUR/month. The project pays back in under 10 months, tokens included.
FAQ
Do you need to train your own model? No — in 95 % of SME cases you use an existing model via API with RAG on your data. Training a model costs 10 to 100 times more and only makes sense at very large scale.
How long for a POC? Plan 3 to 6 weeks for a demonstrable POC on a single scope. Production adds 6 to 12 weeks depending on integrations.
Does data leave the EU? Depending on the provider, yes. We favor offers with EU processing and no reuse for training, and keep a GDPR register.
Can token cost explode? It can be capped with quotas, caching and matching the right model to each task. We size volume from the POC to avoid surprises.
Can we start small? Yes, and it is recommended: one profitable use case funds the next ones. Avoid the all-in-one AI platform up front.
