Nubea on-site functionality

Let us know by WhatsApp when stock returns

A product out of stock does not have to mean a lost sale. Nubea displays an automatic widget in your store, captures the customer's WhatsApp and notifies them at the exact moment the product is available again.

Step 01

The client leaves his WhatsApp

When a product is out of stock, Nubea displays an automatic widget in your store. The customer writes his number and confirms the notice with a click.

Step 02

Nubea listens to your stock

When the product is available again in your store, Nubea automatically detects it. You don't have to do anything or check anything.

Step 03

The notice comes via WhatsApp

Nubea sends a message via WhatsApp instantly with the name of the product and the direct link to buy it. The sale that seemed lost arrives alone.

In a nutshell

What is a back in stock notice?

An available stock notice, also called back in stock, is an automatic system that appears on the page of an out-of-stock product in your online store. The visitor leaves their contact (WhatsApp or email) to receive a notification when the product returns. Nubea integrates this widget directly into your store, without touching code, and sends the notification automatically the moment you update the stock: without manual work on your part.
