EU AI Act Deployer Guide for Belgian SMBs

Most Belgian SMBs using AI tools are "deployers" under the EU AI Act, not providers or developers. This means lighter compliance requirements, but real obligations nonetheless. This guide explains what deployers must do.

Key point: If your business uses AI tools built by others (ChatGPT, Microsoft Copilot, AI-powered accounting software, etc.), you are likely a "deployer" under the EU AI Act. Deployers have specific obligations, but they are less extensive than those for providers who build AI systems.

What is a "Deployer"?

EU AI Act Article 3(4): A "deployer" is a natural or legal person, public authority, agency or other body using an AI system under its authority, except where the AI system is used in the course of a personal non-professional activity.

In practical terms: if your business uses AI tools in its operations, you are a deployer. This includes:

You are NOT a "provider" (with heavier obligations) unless you develop the AI system yourself or substantially modify it. Using an AI tool as-is, even with custom prompts or configurations, typically makes you a deployer.

Key Deployer Obligations

The EU AI Act places specific obligations on deployers. The requirements vary based on the risk classification of the AI system you are using. Most business AI tools (chatbots, content assistants, productivity tools) are classified as minimal or limited risk, which means lighter requirements.

Art. 4 AI Literacy

Deployers must ensure that staff operating or using AI systems have sufficient AI literacy, taking into account their technical knowledge, experience, education, and the context of use.

What this means for SMBs: Staff who use AI tools should understand what the tools do, their limitations, and how to interpret their outputs. This does not require formal AI certifications; proportionate training appropriate to the tools in use is sufficient.

Art. 26 Technical and Organizational Measures

Deployers of high-risk AI systems must take appropriate technical and organizational measures to ensure they use such systems in accordance with the instructions of use provided by the provider.

What this means for SMBs: Follow the documentation and guidelines provided by your AI vendors. If a tool says "do not use for X," do not use it for X. For minimal-risk systems, this obligation is lighter but good practice remains to use tools as intended.

Art. 26 Human Oversight

For high-risk AI systems, deployers must ensure human oversight by natural persons who have the competence, training, and authority to exercise that oversight.

What this means for SMBs: Do not let AI systems make consequential decisions autonomously without human review. For most SMB use cases (content generation, data analysis, customer queries), having staff review AI outputs before acting on them satisfies this requirement.

Art. 50 Transparency to End Users

Deployers of AI systems that interact with natural persons must inform those persons that they are interacting with an AI system, unless this is obvious from the circumstances.

What this means for SMBs: If you use an AI chatbot for customer service, tell users they are chatting with an AI. If AI writes client communications, consider disclosing this. Transparency builds trust and satisfies the legal requirement.

Art. 26 Monitoring and Logging

Deployers of high-risk AI systems must monitor operation and keep logs as appropriate to the nature of the system.

What this means for SMBs: For high-risk systems, maintain records of how the AI is used and any issues that arise. For minimal-risk systems used by most SMBs, this is not legally required but remains good practice for troubleshooting and accountability.

Low-Risk vs High-Risk: Most SMBs Face Lighter Requirements

The EU AI Act uses a risk-based approach. High-risk AI systems (defined in Annex III) face extensive requirements. These include AI used for:

Most AI tools used by Belgian SMBs do not fall into these categories. A ChatGPT-style assistant, an AI writing tool, an AI-powered accounting helper, or an AI chatbot for general customer queries are typically minimal or limited risk.

Limited-risk AI systems (those interacting with natural persons) have transparency obligations (Article 50) but not the full compliance machinery required for high-risk systems.

Minimal-risk AI systems (the majority of business productivity tools) face no specific legal obligations beyond the general AI literacy requirement, though voluntary codes of conduct are encouraged.

August 2026: Key Enforcement Deadline

The EU AI Act entered into force in August 2024. The compliance timeline is phased:

For most SMB deployers, August 2026 is the key date when deployer obligations for high-risk systems are enforceable. However, the AI literacy obligation (Article 4) and transparency obligations (Article 50) apply from August 2025.

Practical Steps for Belgian SMBs

  1. Inventory your AI tools. List all AI-powered tools and features your business uses. Include third-party SaaS with AI features, not just standalone AI products.
  2. Classify by risk. Determine whether any of your AI uses fall into high-risk categories (employment decisions, creditworthiness, etc.). Most SMB uses will be minimal or limited risk.
  3. Ensure AI literacy. Provide proportionate training to staff who use AI tools. They should understand what the tools do and their limitations.
  4. Implement transparency. If AI interacts with customers or clients, disclose this clearly. Add chatbot disclosures, mention AI assistance in relevant communications.
  5. Follow vendor instructions. Use AI tools as documented. Do not repurpose tools for uses they were not designed for.
  6. Document your approach. Keep records of your AI inventory, risk assessments, and compliance measures. This demonstrates good faith if questions arise.
