The problem

Customers want WhatsApp, but your site isn't ready

No visible WhatsApp contact option

Your customers prefer WhatsApp over email or contact forms, but your site doesn't display a clear way to reach you on WhatsApp. The result: they don't contact you at all, or worse, they head to the competitor who does have a prominent WhatsApp widget. Every day, you lose potential sales over a UX detail.

Existing widgets are ugly or slow

Free WhatsApp widgets available on Shopify or WordPress marketplaces are often ugly, slow down the site, aren't responsive, or don't match your brand identity. Some even display advertising for the widget creator. It's impossible to offer a premium experience to your customers.

No GDPR opt-in or tracking

Basic widgets don't collect GDPR consent before initiating a conversation, exposing you to legal risks. They also don't let you track generated conversations or link them to existing customer profiles. It's impossible to measure the widget's impact on your sales.

The solution

A modern, compliant WhatsApp widget integrated with your data

Design customizable to your brand

Fully customize the widget's appearance: colors, position, size, icon, welcome message, notification bubble. The widget integrates seamlessly into your brand identity without breaking your store's design. Mobile and desktop responsive, with smooth animations and optimized performance.

GDPR opt-in and tracked consent

The widget displays a GDPR consent message before opening the WhatsApp conversation. Consent is tracked, timestamped, and kept for at least 3 years in compliance with regulation. Your customers are reassured, your company is protected, and your future WhatsApp marketing campaigns are compliant.

Tracking and attribution

Each conversation initiated from the widget is tracked and automatically linked to the customer profile if possible. Measure conversation count, conversion-to-order rate, revenue generated, and net profit attributed to the widget. Optimize its placement and welcome message to maximize its impact.
