In short

For a WhatsApp chatbot, in most cases nothing existing needs to be replaced: your inventory management system, CRM, calendar, accounting software, or phone system are connected via interfaces. What matters is whether each system has a documented interface — and the time-critical part is almost never the technology, but obtaining the 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 stays in place, and the WhatsApp 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 a WhatsApp 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. A WhatsApp chatbot works with what's already there. The more complete your starting position, 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

Can multiple people reply at the same time?

Yes, that's one of the main reasons for switching. The shared inbox shows who's handling which chat and prevents duplicate replies.

Can we just message customers?

Only with prior consent and within the templates allowed by Meta. Cold outreach via WhatsApp is neither permitted nor smart. Appointment reminders to existing customers, however, are unproblematic.

What happens when switching providers?

The phone number remains your property and can be moved to another Business provider. Histories and templates need to be set up again, that's the only effort.

What does WhatsApp cost in ongoing operation?

Meta charges per conversation, tiered by category. For a typical small business, fees are in the low double digits per month. We calculate this for you in advance based on your message volume.

Is WhatsApp even GDPR-compliant for business use?

Through the official Business API with a European provider, yes, with a data processing agreement and opt-in. The private WhatsApp app on an employee's phone is the version that causes problems — that's exactly what we replace.

How quickly do we need to respond to messages?

There's no Meta requirement, but customer expectations on WhatsApp are minutes, not hours. The automatic replies handle exactly this expectation until someone takes over personally.

Do we need a dedicated smartphone for it?

No. The Business access runs through the number you specify, and the shared inbox is accessible via browser or app for the entire team — not tied to a single device.
