Overview
Maximum Order Quantity (MOQ - MAX) allows you to limit how many units of a product a customer can add to their cart in a single order. This is useful when you want to control bulk purchases, manage inventory limits, or prevent accidental over-ordering. Once set, the store will automatically stop customers from adding quantities beyond the maximum value you define.
This is configured using Custom Fields at the product level.
When to Use Maximum Order Quantity
You may want to use MOQ - MAX when:
- A product has limited stock availability
- You want to restrict bulk purchases
- Certain items should only be sold up to a fixed quantity per order
- You want system-enforced limits instead of manual review
Steps to Enforce Maximum Order Quantity
Step 1: Go to Custom Fields
- Log in to your Admin panel
- Navigate to Catalog → Product Settings → Custom Fields
Step 2: Create a New Custom Field
- Click Add New Custom Field
- Enter a clear Field Name (for example: Maximum Order Quantity)
- For Field Type, select Maximum Order Quantity
- Click on Add to save the custom field
Title
This is the label customers will see on the product page. Use a clear, customer-friendly name so buyers immediately understand what the limit is about.
Description
This text is for your internal reference only. It appears in the admin view of the product details and helps your team understand how or why this field is being used.
Field Type
This defines what the field actually does. In this case, you’ll select Maximum Order Quantity, which tells the system to enforce a quantity rule on the product.
Default Value
This sets a preset quantity for the field. Keep in mind, adding a value here doesn’t automatically enforce MOQ across all products. The field must still be enabled on each product individually.
Think of this as a ready-to-use value that’s already filled in when you turn MOQ on for a product, saving you a step later.
Step 3: Apply the Field to Products
- Go to Catalog → Products
- Edit the product where you want to enforce a maximum quantity
- Locate the Custom Fields section
- Enter the maximum quantity allowed (for example:
10) - Save the product
What Happens on the Storefront
- Customers can add items to the cart up to the maximum quantity
- If they try to increase the quantity beyond the limit, the system prevents it
- No promo codes or custom scripts are required
