Why AI Automation?

Repetitive tasks cost time and money. With the right tool, you automate processes, connect your systems, and put AI to productive use.

Accelerate Processes

Classify emails, summarize meetings, sync data – all automatically, around the clock, without manual effort.

Ensure Data Privacy

Especially for SMEs, the choice of tool determines whether your data stays in the EU and GDPR compliance is maintained.

Control Costs

From pay-per-use API models to fixed-cost licenses – the differences are enormous. We show you what really pays off.

Our Setup Recommendations

Three battle-tested configurations – which one is right depends on your use case: How sensitive is your data? How complex is the automation? How many users are involved?

LLM via API (e.g. OpenAI) + n8n

Language models hosted by e.g. OpenAI, combined with n8n as automation platform. The most affordable solution – ideal for public data and non-critical processes.

  • Extremely affordable (pay-per-use)
  • Maximum flexibility, no licenses
  • Quick start, huge community
  • Data at OpenAI (USA)
  • Own maintenance effort
Best choice for: Public data, maximum flexibility, small budget

LLM in Azure + n8n

Language models in your own Microsoft tenant with EU data residency. Slightly more expensive, but no data privacy issues – even with sensitive company data.

  • EU data residency, GDPR compliant
  • Full control in your own tenant
  • High flexibility + cost-effective
  • Azure admin know-how required
  • Slightly more expensive than OpenAI directly
Best choice for: Sensitive data, compliance requirements, complex workflows

Microsoft Power Platform

The “light” version of Power Automate integrated in M365 licenses – usable at no extra cost. Everything is already integrated in your Microsoft environment, ideal for simple use cases.

  • No additional costs for simple flows
  • Seamless MS 365 integration
  • GDPR compliant, no IT setup needed
  • Gets expensive fast for complex use cases (licensing model)
  • Less flexible, MS ecosystem only
Best choice for: Simple automations, few users, pure MS environment

Cost Comparison

What does AI automation really cost? A realistic comparison for a company with 50 users of a more complex AI automation.

OpenAI/Azure + n8n

Pay-per-use – variable costs based on consumption

API costs (GPT-4.1) ~$10/month*
n8n server (Hetzner etc.) ~€10-15/month
User licenses €0
Total/month ~€20-30
*At ~10-20 requests/person/month. Per 1M tokens: $2 input / $8 output. One prompt pair = ~1,000-2,000 tokens.

Microsoft Power Platform

Fixed costs – license-based per user or bot

Power Automate Premium (50 users) ~€750/month
Alternative: 1 Process Bot ~€150/month
Copilot Studio Add-on ~€185/month
Important: With Premium, every user who runs or manually triggers a flow needs their own license.

Data Privacy & Compliance

A key criterion for SMEs. Not every tool offers the same level of security.

OpenAI.com API

US data storage, no DPA. Only suitable for non-sensitive data.

Azure OpenAI + n8n

EU data residency, GDPR compliant. Microsoft compliance framework. Ideal for sensitive data.

Power Platform

EU data residency, GDPR compliant. Fully managed by Microsoft. No own server needed.

Our Conclusion:
The right solution depends on your use case.

How sensitive is your data? How complex is the automation? How many users are involved? We help you find the right setup.

API + n8n

Maximum flexibility, lowest budget – ideal for public data and quick onboarding.

Azure + n8n

EU data residency, GDPR compliant, full control – ideal for sensitive data and complex workflows.

Power Platform

Seamlessly integrated into Microsoft 365, no IT setup – ideal for simple use cases in the MS ecosystem.
