# Introduction

> Need Alert notifies your customers the moment what they are waiting for becomes available.

**Need Alert** is "notify me when it happens" for any business. It takes the "notify me when it's back" button from online stores to the bakery taking bread out of the oven, the clinic opening a last-minute slot, a movie premiering at the cinema, the blood bank that needs a specific blood type.

Here's how it works: your customer subscribes to an item through a QR code or a link. When the item becomes available, you send an alert and **all subscribers are notified at the same time**, on their phones. There's no order, no position, and no waiting time: whoever subscribed gets the alert.

## Why use it

* **One alert per item.** Each person only gets the alert they asked for. Unlike a WhatsApp group or a social media post, nobody is bothered with what they don't want.
* **Works without a website.** A QR code on the shop window, the shelf, or a poster is enough to collect subscriptions.
* **No app to install.** Your customers use Need Alert in the browser and can add it to their home screen if they want.
* **You see the demand.** The dashboard shows how many people are waiting for each item, in real time.
* **Predictable cost.** Before each dispatch you see how many people will be notified and how many credits it uses.
