How to Choose the Right B2B AI Agent Vendor: 8 Criteria

The market for B2B AI agents is growing fast. There are dozens of vendors, each with their own promises and pricing models. How do you separate the wheat from the chaff? Here are the eight criteria that really matter.

1. Domain Expertise

Choose a vendor that understands your industry. An AI agent for an accounting firm has different requirements than one for a logistics company. Ask for reference cases in your sector.

2. Integration Capabilities

The vendor must connect to the tools you already use: your CRM, ERP, communication platforms. Explicitly ask about native connectors and open API documentation.

3. Security and Compliance

For European companies, GDPR compliance is non-negotiable. Ensure data is processed within the EU, ask about ISO 27001 certification, and review the data processing agreement carefully.

4. Scalability

Starting with one agent for one team? Make sure your vendor can scale to ten agents for the entire company — without starting over.

5. Pricing and TCO

Watch for hidden costs: implementation fees, training hours, integration work, support. Calculate the Total Cost of Ownership over 12 months, not just the license price.

6. Support and Onboarding

A good vendor guides you from pilot project to full rollout. Ask about SLAs, response times, and dedicated support — especially in the first three months.

7. AI Model Transparency

Which AI model powers the agent? Can the vendor explain why an agent makes a decision? Explainability and auditability are crucial for compliance-sensitive sectors.

8. Track Record and Reviews

Ask for customer cases, check reviews on G2 or Capterra, and talk to existing customers. A young vendor can be excellent, but proven results provide certainty.

Conclusion

You choose the right AI agent vendor not based on the most impressive demo, but on domain knowledge, integrations, compliance, and proven results. Take the time for a thorough evaluation — the investment pays off.
