# How to Limit Order Quantity/Amount and Set Product Increment

The **Order Limit (OL)** function is a great way to **encourage larger purchases** and control minimum or maximum order quantities.\
However, for **B2B stores**, you can take this even further by **combining Order Limit with Quantity Increment (QI)** — helping you both **increase sales volume** and **manage inventory efficiently**.

This article walks you through a typical example to show how the two features work together.

***

### 🎯 **Example Use Case**

**Goal:**\
Customers must buy **at least 5 products** from the **“Summer Fruit Collection”** to check out.\
In addition, the **order quantity must increase in multiples of 10**.

| Condition          | Rule                                      |
| ------------------ | ----------------------------------------- |
| Minimum order      | 5 products from “Summer Fruit Collection” |
| Quantity increment | Must be in multiples of 10                |

***

### ⚙️ **Step 1: Set Up the Order Limit Rule**

1. Go to **Order Limit (OL) Rules** in your app dashboard.
2. Click **Create New Rule**.
3. Configure the following:
   * **Rule Type:** Choose based on your business goal (e.g., *Order Quantity* or *Order Amount*).
   * **Minimum:** Enter **5** to require at least 5 products.
   * **Apply to Products:** Choose **Product collections → Summer Fruit Collection**.
4. Click **Save** to apply the settings.

✅ *This ensures customers cannot check out unless they buy at least 5 products from the selected collection.*

***

### ➕ **Step 2: Set Up the Quantity Increment Rule**

1. Go to **Quantity Increment (QI) Rules**.
2. Click **Create New Rule**.
3. Configure the following:
   * **Apply to Products:** Choose **Product collections → Summer Fruit Collection**.
   * **Quantity Increment:** Enter **10 (Order quantity)**.
4. Click **Save** to apply the settings.

✅ *This ensures customers can only increase quantities in multiples of 10 (e.g., 10, 20, 30…).*

***

### 🧾 **On the Storefront**

When a customer’s cart doesn’t meet both rule requirements (minimum 5 items and quantity in multiples of 10), a **notification message** will appear automatically:

> ⚠️ *Your cart does not qualify based on the current order rules.*

Customers will only be able to proceed to checkout once all rule conditions are satisfied.

***

### 💡 **Tips**

* Combine **Order Limit** and **Quantity Increment** to guide customers toward your desired purchase volume.
* Use this setup for **wholesale collections** or **bundled products** where bulk orders are common.
* Messages shown on the cart page can be customized in the app settings for better communication with your buyers.
