# [Intergration] Pareto Quantity Breaks & Discount X Pareto - Order Limits Quantity

# Integration Case: Limit Discount Usage per Offer
The **Maximum allowed uses** feature lets you control how many times a discount offer can be redeemed by integrating with **Pareto Limit**.
This helps protect margins, prevent over-redemption, and automatically stop discounts when limits are reached.

## Before you start
To use **Maximum allowed uses**, you need:
* An active offer in Pareto
* The **Pareto Limit** app installed
If Pareto Limit is not installed, you’ll be prompted to install it.

## How Maximum allowed uses works
### When Pareto Limit is not installed
* A prompt explains the benefits of limiting discount usage
* Click **Install to enable Limit discount** to open the app listing
* Limits cannot be configured until installation is complete

### When Pareto Limit is installed but not set up
* Message displayed:Save your offers to lock in your setup, then use Pareto Limit to control how many times the discount can be redeemed.
* Click **Set up in Pareto Limit** to create a limit rule for the offer

### When Pareto Limit is installed and a rule exists
* Limit fields are shown in Pareto Quantity as read-only:
    * **Limit total usages** (for example: 10 – Lifetime)
    * **Limit usage per customer** (for example: 1)
* Click **Edit in Pareto Limit** to open create the respective rule type in Pareto Limit
* If a limit value is **0**, that limit field is hidden in Pareto Quantity

### When the offer is turned off
* All limit fields remain disabled
* **Edit in Pareto Limit** is disabled
* You can not create/edit limit for specific discount rule when that discount offer is not active

## Checkout behavior (settings in Pareto Limit)
When a discount reaches its usage limit:
* The discount stops applying automatically
* Customers see a warning on the **cart page** that the discount has reached its usage limit
* No manual action is required

For stores on **Shopify Plus** using the **Pareto Limit paid plan**:
* Checkout blocking is supported
* Customers are prevented from completing checkout when a limited discount has reached its usage cap
* A clear warning message is displayed at checkout explaining why the discount cannot be used
**Note**
Checkout blocking is available only on Shopify Plus and requires an active Pareto Limit paid plan.

## Why use Maximum allowed uses?
* Protect your profit margins
* Prevent accidental over-redemption
* Run limited promotions safely
* Control discount abuse at checkout
