# Installing Preorderline Pro - Preorderline 1.x documentation

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

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

Preorderline Pro is an add-on: it adds payment options, automatic release, limits and the "When out of stock" mode to Preorderline, which stays installed and keeps doing everything else. You need both.

## Before you start

- **WooCommerce** and **Preorderline** 1.0.0 or later, installed and active. If you don't have Preorderline yet, install it from **Plugins → Add New Plugin** (search for "Preorderline"); see **Installation**.
- The **preorderline-pro.zip** file and the **license key** from your purchase email. Both are in the email Lemon Squeezy sent after you bought Preorderline Pro.
- To charge saved cards on release: the **WooCommerce Stripe Gateway** plugin, set up with saved cards. Everything else works with any payment method.

## Install and activate

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

WordPress won't activate Preorderline Pro while Preorderline 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 Preorderline Pro:

![The license box under Preorderline Pro on the Plugins screen](https://storage.extendiment.com/media/1018/screenshot-6-334f8e6a.png)

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. The key activates Preorderline Pro on this site only; 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

- **WooCommerce → Settings → Products → Pre-orders** now has **Customers pay**, **Deposit**, **Deposit refunds**, **Balance reminder** and **Release** settings above the texts.
- A product's **Pre-order** tab has **When out of stock** among its modes, and **Customers pay**, **Deposit** and **Pre-order limit** fields.
- **WooCommerce → Settings → Payments** lists **Pay when a pre-order is released**.

## While Preorderline Pro isn't active

Its settings stay saved. Preorderline leaves them alone, and as soon as Preorderline Pro is active again, products paid on release or with a deposit, limits, "When out of stock" products and your store-wide payment settings work again, with nothing to re-enter. Orders placed with them are picked up too.
