01Where each channel actually wins
A website chat widget catches a visitor at the exact moment they are reading your pricing page or your service list, with zero prior relationship, which is the situation most search and ad traffic arrives in. A WhatsApp bot works from the opposite starting point: the person already has your number saved, usually from a referral, a past order or a physical location, and is messaging a channel they already use for everything else in their life. Trying to run the wrong one first means building for traffic you do not actually have yet.
- Website chat fits cold traffic from search and ads with no prior relationship
- WhatsApp fits warm traffic that already has your number saved
- Building the wrong one first means solving a problem you do not have yet
02What PROOF48 actually builds today
The AUTOMATE plan, at 2,997 EUR a month, ships an AI website chatbot that qualifies a visitor and books them directly, alongside DM and email auto-responders, booking automation and a CRM feeding from the same customer record. WhatsApp is deliberately not part of that bundle, because a WhatsApp bot needs its own conversation design and usually its own integration into whatever booking system already exists, work that only makes sense once the real message volume is known. PROOF48 builds it as a separate custom project once we understand the real volume and the systems it needs to talk to.
- AUTOMATE covers site chat, DM and email replies, booking and a CRM together
- WhatsApp needs its own conversation design and its own system integration
- A WhatsApp bot is priced as a custom build once volume is known
One customer record, whichever channel they pick
Korean Cosmetics runs its store and its app from one codebase in 12 languages, and the cart follows the same customer between the website and the app instead of resetting when they switch. The same discipline applies to chat: whichever channel a customer picks first, the record behind it should not force them to repeat themselves on the next one.

Can I start with just the website chat widget and add WhatsApp later?
Yes. The website chatbot on AUTOMATE stands on its own, and a WhatsApp bot can be priced as a separate build once you can see the real conversation volume it would need to handle.
Does the website chatbot connect to WhatsApp at all?
No. A custom WhatsApp build can be wired into the same CRM, but the WhatsApp channel itself remains a separate, custom-priced build, not something AUTOMATE connects automatically.
Where PROOF48 fits
Match the channel to where your traffic actually comes from: cold traffic to a website widget, warm traffic to WhatsApp. PROOF48 builds the first inside AUTOMATE, at 2,997 EUR a month, and prices the second as a custom project once the volume is known.
