# How to Add a Buy All Stock Button

The Buy all stock button lets a customer add every available unit of a product to the cart in one click. It is handy for clearance and wholesale lots. This feature is free in the [Min Max Step Quantity Limits Manager for WooCommerce](https://wpfactory.com/item/product-quantity-for-woocommerce/) and works with products that have managed stock.

### Before you start

- The product must have **Manage stock** enabled (WooCommerce **Inventory** tab) with a stock quantity set.

### Steps

1. Go to **WPFactory > Quantity Manager** (also reachable at **WooCommerce > Settings > Product Quantity**).
2. Open the **General** section and find **Buy all stock button**.
3. Tick **Create a Buy all stock button on product page** (`wpfmmsq_buy_all_stock_button_enabled`).
4. Optionally set the **Button label**, **Button class**, **Alert message** and **Success message**.
5. Click **Save changes**.

### Options reference

| Label | Option ID | Default | Free/Pro |
| --- | --- | --- | --- |
| Buy all stock button (enable) | `wpfmmsq_buy_all_stock_button_enabled` | No | Free |
| Button label | `wpfmmsq_buy_all_stock_button_label` | Buy all stock | Free |
| Success message | `wpfmmsq_buy_all_stock_button_success_msg` | %qty% x %product_title% has been added to your cart. | Free |

**Note:** the button only works on products (or selected variations) with managed stock. On a variation without managed stock, the **Alert message** is shown instead. The **Success message** accepts `%qty%` and `%product_title%`.

### Get more control

This feature is free.
