FAST Whatsapp: Chat & Leads
shopify whatsapp chat app
Turn chats into checkouts with a bubble button.
The problem
Most shoppers who hesitate never ask. They hit a question about sizing, shipping or stock, find nothing but a contact form, and leave without a word. Email feels slow and formal, and a live-chat widget nobody staffs is worse than none at all. Meanwhile the channel your customers actually use all day sits unconnected to your storefront.
How it works
Install and place the button
Add the chat bubble from the theme editor. Choose where it appears — every page, product pages only, or a specific set — and how it looks on mobile versus desktop.
Set your hours and message
Define business hours so the widget shows availability honestly, and write a prefilled message that includes the product the shopper is looking at.
Answer where they already are
Taps open WhatsApp with context attached. You reply from your phone, and the conversation continues in a channel that keeps its history.
What you get
Smart prefilled messages
Every conversation opens with the product name and link already filled in, so you never start with 'which item do you mean?'.
Business hours
Show availability honestly. Outside your hours the widget sets expectations instead of leaving a message unanswered.
On-brand styling
Colour, position, size and label are all yours. The bubble reads as part of the store, not a bolted-on third-party widget.
Responsive on every device
Tested across mobile, tablet and desktop, including the safe areas on iOS where fixed elements usually collide with system UI.
Flexible placement
Show the button everywhere, or only where it earns its place — product pages, cart, or a specific collection.

Questions about FAST Whatsapp
Do I need a WhatsApp Business account?
A regular WhatsApp number works. WhatsApp Business is worth having for away messages and a catalogue, but the app does not require it.
Will the chat button slow my store down?
No. The widget is a small script that loads after your page content, so it does not compete with your images or block rendering.
Can I show the button only on certain pages?
Yes. Placement is configurable per page type, so you can limit it to product pages or the cart if that suits your flow better.
Does it work on mobile?
Yes, and that is where most of the value is. Tapping the bubble on a phone opens the WhatsApp app directly with your prefilled message attached.
How much does it cost?
It is free. There is no paid tier, no conversation cap and no commission.
