The essentials
An AI agent or automation project for a French SME costs between €3,000 and €25,000 to deploy depending on complexity, plus a monthly subscription of €80 to €600 for hosting, maintenance and evolutions. A 20-to-50-employee SME structuring a genuine automation program in its first year typically budgets between €25,000 and €60,000.
Why such a wide range
The price of an automation or AI agent project depends on three main variables: the complexity of the business logic to reproduce, the volume of data or requests to process, and the level of integration with your existing tools. A connector syncing two SaaS tools via n8n has nothing to do with a business assistant that queries a document base of several thousand pages and must stay GDPR compliant.
Budget by project type
| Project type | Deployment | Monthly subscription | Typical timeline |
|---|---|---|---|
| Simple automation (n8n/Make, 1-3 connectors) | €3,000 - €8,000 | €80 - €150 | 2 to 4 weeks |
| Business workflow with conditional rules | €8,000 - €15,000 | €150 - €300 | 4 to 8 weeks |
| Business assistant connected to a document base | €12,000 - €20,000 | €200 - €400 | 6 to 10 weeks |
| Autonomous multi-step AI agent, private LLM integration | €18,000 - €25,000+ | €300 - €600 | 8 to 14 weeks |
These ranges cover scoping, development, testing and deployment. They don’t include internal change management costs (team training, process adjustments), which generally represent an additional 10 to 20% in internal time.
The factors that make the price vary
The complexity of the business logic. A simple rule (“if stock drops below X, reorder”) costs little to automate. A decision that depends on dozens of edge cases, exceptions and human trade-offs costs significantly more to model correctly.
The volume of data to process. Extracting information from 50 invoices a month doesn’t have the same infrastructure cost as processing 5,000. Volume affects the choice of architecture, the robustness required and recurring hosting costs.
The level of integration. Connecting two SaaS tools via their official APIs is fast. Interfacing with a legacy system with no modern API (an old ERP, AS400) requires a dedicated abstraction layer, which increases both budget and timeline.
Compliance and confidentiality requirements. A project handling health, financial or other sensitive personal data requires controlled hosting (France or on-premise), stronger documentation and additional security testing. See the GDPR/AI Act compliance page.
The choice of tool. No-code automation (n8n, Make) is structurally cheaper than custom development, but quickly hits its limits on complex logic. See the n8n vs Make vs custom comparison.
Public funding: worth exploring before budgeting alone
Several French public schemes can reduce the out-of-pocket cost of an automation or AI project for an SME: Bpifrance diagnostics and support programs, France Num grants for the digital transformation of small and medium businesses, regional schemes depending on your location. Amounts and eligibility criteria change every year and by region: we recommend checking your eligibility directly with Bpifrance or your regional council before finalizing a budget, rather than relying on a generic figure that would quickly become outdated.
