WhatsApp Business pays off, but only with the right setup
Almost everyone is on WhatsApp, and more and more businesses use messengers to talk to customers. In five charts, I show what speaks for it, how the app differs from the business platform and what data protection and costs mean.
Anyone who can reach their garage, practice or studio on WhatsApp doesn’t have to call, doesn’t have to wait and can simply send a photo. No wonder many businesses have been using the channel for a long time, often on a private phone. That’s exactly where the problems start.
Almost everyone is on WhatsApp
As early as 2022, according to the ARD/ZDF online study, 68 % of people in Germany aged 14 and over used WhatsApp daily and 82 % at least once a week. By 2024, only 2 % did without it entirely. Older people are on it too: in 2022, 80 % of 50 to 69-year-olds were already on WhatsApp at least weekly.

Messengers are replacing fax and letters
The channel has caught on in companies, too. According to Bitkom, two thirds of companies with 20 or more employees used messengers frequently for internal or external communication in 2025 (66 %, 2023: 54 %). Over the same period, fax fell from 33 to 18 %. In the skilled trades, 62 % of businesses use messengers such as WhatsApp.

Businesses feel the pressure from their customers. 85 % of trade businesses say their customers expect them to be reachable at all times, 89 % that they expect individual quotes.

Being reachable doesn’t mean replying instantly, though. Even in private chats, 69 % of people sometimes leave messages sitting for a while, according to Bitkom, and 87 % are understanding when others reply later. What matters is that no inquiry gets lost and customers know when to expect an answer.
By the way, there is no representative study of how many people in Germany would like to message businesses on WhatsApp. And the often-quoted open rate of 98 % has no reliable source either.
App or business platform: the key difference
WhatsApp comes in two versions for businesses. The WhatsApp Business app is free and meant for small businesses: one number, one phone, a few people. Even the app offers greeting and away messages, quick replies and a catalog for your services. The WhatsApp Business Platform, often called the API, is an interface. It connects to a CRM, several team members can reply, and processes like appointment confirmations run automatically. For that, you need a service provider.

Data protection: the address book is the problem
The WhatsApp app regularly syncs the phone numbers in your address book, including those of people who don’t use WhatsApp at all. The Bavarian data protection authority therefore considers compliant use of WhatsApp in companies “as a rule” not justifiable. For customer contact, it says use is only possible if the address book issue is solved and there is always an equivalent alternative way to get in touch.
For advertising, there’s an additional rule in Germany: no promotional messages without prior explicit consent. WhatsApp itself also requires that people have agreed to be contacted. This section is not legal advice.
What a message costs
The app is free. On the business platform, Meta has been charging per message since July 2025. What customers send is free, as are the first 1,000 replies a month within 24 hours of their message. Templates such as appointment confirmations cost around 4.6 cents in Germany, marketing messages around 11 cents. Service provider fees come on top.

Where to start
- A dedicated business number. Not your private phone, but a number that belongs to the business, with clear response times.
- The right setup. For a few inquiries, the app can be enough, for example on a separate device without private contacts. For several team members and automatic confirmations, the business platform with a CRM is the better way.
- Consent and an alternative. Contact only with permission, marketing only with explicit consent, and always offer phone or email as well.
I connect WhatsApp to a CRM in which every inquiry has a status and an owner, whether it comes in via WhatsApp, a form or email. If you want to know which setup suits your business, get in touch.
