The bot is allowed; its replies are no longer free. Most salons use the WhatsApp Business app on their main number, so the product needs Coexistence and Tech Provider status. Above 1,000 replies a month, every answer costs money.

Search demand: what people type
Google autocomplete, German, region Germany, 28 Oct 2026
15 phrase groups, no volumes. Autocomplete shows that a phrase exists, not how often. A missing suggestion does not prove nobody searches it.
Customers search "online buchen"Near me, a city or a platform name. Not WhatsApp.
WhatsApp booking is not searchedPeople message their salon directly, so this does not prove nobody books that way.
Owners look for free"kostenlos" follows salon software, studio software and the WhatsApp API.

Economics: what one salon costs to run
Our arithmetic on the published prices. About 5 bot messages and one reminder per booking.
Monthly running cost per salon vs the price, €

Busy salon: 500 charged replies ≈ €22.80, 300 reminders ≈ €13.68 meetergo, Twilio on about 3,300 messages ≈ $16.50 Twilio, AI about $3 OpenAI. With 360dialog's €49 per number, every salon is above €29.
Churn is a cross-industry benchmark, not salons: a scenario, not a forecast.

Verdict and what would reopen it
STOP
Do not build the idea as written. Every version we could define already has a seller at or below €29, and the one promise that would make salons switch, "keep your calendar", has no published way in.
One salon software without its own AI agent (Shore, studiolution, Salonized) lets a bot write bookings, in writing
It promotes the add-on to its salons: market and sales channel in one
€29 with a booking cap, so a busy salon does not cost more than it pays
Bsmaller, already contested
Salons without booking software.
Keeps the salon's WhatsApp number and writes into Google Calendar
Already targeted by Time Globe, term-in and Glammaro
Only if pilot salons say why they would not pick those
Riskiest assumption
Salons will pay a separate vendor €29 a month for AI booking when their own booking software sells or bundles the same thing.
Legal must-check before launch
AI disclosure at the first message Art. 50 AI Act, from 2 August 2026, not delayed Cooley. Meta's AI-provider clause and a human handover. Data processing agreements with Meta, the messaging provider and the AI provider. Consent-based outreach § 7 UWG.
A second reviewer argued for CHANGE. Kept: with Twilio a small salon costs about €11, not €49; Time Globe costs 99,90 € at 100 bookings; Salonized has 2018 booking endpoints behind whitelisting and Timify sells API access. These set the condition to reopen, not evidence to build.

Read it right. A pass shows payment intent, not retention. Before scaling, run the bot 30 days with the first payers: correct calendar writes, handovers to staff, and who pays for month two.
