KI-Beratung: AI Interfaces & System Integration

AI Interfaces &System Integration

AI is only as good as its connection to your existing systems. We develop tailor-made REST APIs, webhooks, and CLI tools that link your CRM, ERP, ticketing system, or custom applications to modern AI models — without changing systems, without data loss. The result: your existing software landscape becomes intelligent without having to rebuild everything from scratch. We handle the technical integration end to end — from concept to production.

Challenges you'll recognise

  • You want to bring AI into your daily workflows, but your CRM, ERP, or custom-built system has no native AI support — and switching platforms is not an option.
  • Your team manually copies data between systems every day because there's no clean integration between them.
  • You already use an AI tool, but it operates in complete isolation — without connection to your existing data and processes, it delivers little real value.

Services in detail

Good to know

  • API-First Is the Norm

    Most modern business applications — CRMs, ERPs, ticketing systems — expose REST APIs. That's the technical foundation for AI integrations: anyone who uses these APIs cleanly can extend existing software intelligently without having to touch the underlying system.

  • Abstraction Protects Investment

    A well-designed AI integration architecture separates the AI layer from the business logic. If an AI model or third-party provider changes, you don't have to rebuild the entire integration — only the adapter layer needs replacing.

  • Legacy Systems Are Not a Blocker

    Systems without an official API can often be connected through alternative routes: direct database access, RPA interfaces, or structured file exports. What looks like a technical dead end in many projects is solvable — it just requires a different approach.

Frequently asked questions

Which systems can be connected to AI models?
Essentially any system with an API or export function — which means virtually all modern CRMs (Salesforce, HubSpot, Pipedrive), ERPs (SAP, Microsoft Dynamics), ticketing systems (Zendesk, Freshdesk, Jira), and of course custom applications. For legacy systems without an API we assess alternative connection approaches such as database access or RPA interfaces.
What happens when the AI model or API changes?
We build interfaces so that model updates can be rolled out transparently with minimal effort. To achieve this we abstract the AI layer in the architecture, meaning a switch from GPT-4 to Claude or another model has no impact on your existing systems.
How are security and data protection ensured during integration?
We implement from the start: API key management, role-based access controls, encrypted data transfer (TLS), logging with audit trail, and — where required — masking of sensitive fields before they are sent to external AI models. On request we use self-hosted models or EU-based infrastructure.
How long does a typical AI system integration take?
A straightforward API integration between an existing system and an AI model is often in production within two to four weeks. More complex scenarios involving multiple systems, custom data pre-processing, and monitoring setup take correspondingly longer. We estimate realistically and deliver in short iterations.
Can we maintain and extend the integration ourselves?
Yes, that is an explicit goal. We document all interfaces fully and build in a way that your internal development team can understand, maintain, and extend the integration. On request we train your team after go-live and remain available for questions.
