Connecting an AI chatbot with existing systems

Does everything need to be replaced for this? Usually not. What can be connected to an existing system landscape, where the limits are, and which part typically takes the longest.

In short

In most cases, nothing existing needs to be replaced for an AI chatbot: inventory management, CRM, calendar, accounting, or phone systems are connected via interfaces. What matters is whether the respective system has a documented interface — and the time-critical part is almost never the technology, but obtaining access credentials.

01 — Integration

Connection with existing systems

The most common misconception is that everything needs to be replaced. In most cases, your existing system landscape remains in place, and the AI chatbot builds on top of it — through interfaces, not replacement.

What gets connected in practice: ERP, CRM, calendar, accounting, phone system, newsletter system, website. What matters is whether the respective system has a documented interface. Where none exists, there's usually a workaround — but that costs effort and needs to be clarified up front, not discovered later.

The time-critical part is almost never the technical integration, but obtaining access credentials. Starting early here noticeably shortens the project timeline.

02 — Requirements

What you need for an AI chatbot

  • A clearly defined trigger. Not “we should do something with AI,” but a process that demonstrably costs time or orders today.
  • Existing content or data. An AI chatbot works with what's already there. The more complete your starting point, the shorter the setup.
  • Access to the systems involved. Whoever manages the credentials needs to be involved from the start — this is, in our experience, the most common cause of delays.
  • One decision-making contact person. One, not three.
  • Willingness to refine after launch. The first weeks in real operation show what was missing in the concept. That's normal and accounted for.

03 — Bottlenecks

What typically causes delays

  • Content and deliveries. By far the most common cause of delay. Text, images, price lists, access credentials — what's missing blocks progress.
  • Decisions. When it's unclear who approves, the project waits. A named contact person with decision-making authority noticeably shortens the timeline.
  • Access to third-party systems. Getting access to inventory management, phone systems, or CRM regularly takes longer than the integration itself.
  • Endless review rounds. Two correction rounds are normal, five are a sign that the goal wasn't clear at the start.

04 — Questions

Frequently asked questions

Does this also work on a WordPress site?

Yes. The integration is a single code snippet in the footer and works the same on WordPress, Shopify, Webflow, Wix, TYPO3, or a custom-built site.

How much work does this create for us?

At the start, about two to three hours for gathering content and one alignment round. After that, nothing regular — unless you want to add new topics, which works through a simple document.

What happens to our customers' data?

The conversations run through servers in the EU, no training is done with your data, and we write the appropriate section for your privacy policy. On request, chat logs are automatically deleted after a set period.

Can we turn the bot off again?

Anytime, with one click. The snippet remains, the bot is gone. There's no minimum term that binds you.

Doesn't an AI chatbot just make up answers?

A free-running language model does. That's why we build the bot so it only answers from a verified knowledge base and provides the source. If it finds nothing, it says so and redirects — that's the most important part of the configuration.

Do we have to label the chatbot as AI?

Yes. Since August 2026, the transparency requirements of Article 50 of the EU AI Act apply: Anyone communicating directly with an AI system must be able to recognize it. We build the labeling in as standard, it costs nothing extra.

Does this even pay off for us?

The calculation is simple: requests per week times processing time times hourly rate. With twenty repeat questions per week and seven minutes each, that's a good two hours of work — every week. We calculate this with your real numbers before the quote.
