# Installing Stockpool Pro - Stockpool 1.x documentation

> Upload the Stockpool Pro zip, activate it next to Stockpool, and enter your license key.

> [!NOTE]
> This is part of **Stockpool Pro**.

Stockpool Pro is an add-on: it adds attribute rules, kits, bundle support and CSV import to Stockpool, which stays installed and keeps doing everything else. You need both.

## Before you start

- **WooCommerce** and **Stockpool** 1.0.0 or later, installed and active. If you don't have Stockpool yet, install it from **Plugins → Add New Plugin** (search for "Stockpool"); see **Installation**.
- The **stockpool-pro.zip** file and the **license key** from your purchase email. Both are in the email Lemon Squeezy sent after you bought Stockpool Pro.

## Install and activate

1. Go to **Plugins → Add New Plugin** and click **Upload Plugin** at the top.
2. Choose `stockpool-pro.zip` and click **Install Now**.
3. Click **Activate Plugin**.

WordPress won't activate Stockpool Pro while Stockpool or WooCommerce is inactive; it lists what's missing instead. Activate those first.

## Enter your license key

Back on the **Plugins** screen, there's a box under Stockpool Pro:

1. Paste the license key from your purchase email.
2. Click **Activate**.

The box turns green and shows the end of your key and, for a yearly license, the date your updates run until. See **Licenses and updates** for moving it to another site.

> [!NOTE]
> The features work as soon as the plugin is active, with or without a license. The license is what lets WordPress download updates.

## Check it works

Open any pool on **Products → Shared stock**. Below **Settings** there are two new boxes, **Made from other pools** and **Which products use it**; see **Attribute rules** and **Kits**. The pool list also has an **Import CSV** button.

## While Stockpool Pro isn't active

Rules and kits stay saved on your pools. Stockpool keeps them but doesn't act on them, and as soon as Stockpool Pro is active again they work, with nothing to re-enter. Stockpool updates the stock status of the products they link within a minute or so of activating.
