WhatsApp + TWINT + Ads: conversational e‑commerce is ready. Are you?

WhatsApp is no longer just a messaging app. It has become a complete sales interface, massively adopted by users. But one question remains: are Swiss and European companies, B2B as well as B2C, ready?

In 2025, the figures are fairly clear:

• 3 billion monthly active users worldwide (DataReportal, January 2025)
• 5.4 million in Switzerland, close to the entire working population
• More users than YouTube globally

The usage is there. The momentum is established. And with the gradual rollout of WhatsApp Ads, brands can now gain visibility… from within WhatsApp itself.

Payment inside WhatsApp: the shift has begun

Since 2023, WhatsApp has been testing native payment integration with Stripe in Singapore. The user discovers a product, interacts with the brand, and pays inside the conversation. A smooth experience, with no break and no learning curve.

There is already a precedent: Brazil, where peer-to-peer payment via Facebook Pay has been possible since 2018.

In Switzerland, TWINT now lets companies send a payment link over WhatsApp. It is simple, direct and perfectly suited to mobile use. Not native yet, but the journey works and is production-ready.

WhatsApp Business: solid foundations, but limited

In its official version (app or API), WhatsApp Business lets you:

• Create a business profile
• Add a product catalogue (up to 500 items)
• Set up simple automatic replies

But automation stays limited: no intent detection, no native AI, no direct integration with a CRM or a more complex technology environment.

A new generation of "WhatsApp native" companies

With advertising arriving inside WhatsApp and integrated sales tools, it is now possible to imagine a company that operates exclusively through WhatsApp.

• Discovery through an Ads campaign
• A guided sales journey inside the conversation
• Built-in payment
• Post-purchase follow-up and direct customer relationships

All of it with an unprecedented level of personalisation, made possible in particular by AI.
