What is WooCommerce Limit Quantity Per Product?

WooCommerce’s Limit Quantity Per Product feature allows you to define the minimum and maximum number of units a customer can purchase per order. This feature is particularly useful for:

  • Wholesale and B2B Stores: Setting bulk order requirements
  • Limited-Edition or Exclusive Products: Restricting maximum purchase quantity
  • Subscription and Recurring Orders: Setting specific product limits
  • Preventing Stock Hoarding: Stopping customers from purchasing excessive quantities

For example:

  • Minimum Order Quantity: Customers must buy at least 3 units of a product before checkout.
  • Maximum Order Quantity: Customers cannot buy more than 10 units per order.

This ensures fair distribution, prevents stock depletion, and allows store owners to manage inventory effectively.

Why Should You Set Quantity Limits in WooCommerce?

1. Prevent Overstocking or Understocking Issues

By controlling product quantities, you can prevent customers from buying too many units and depleting stock or buying too few, affecting overall sales.

2. Improve Wholesale and Bulk Purchase Rules

For wholesale stores, you can enforce a minimum order quantity (MOQ) to ensure that customers purchase items in bulk.

3. Manage Limited-Stock or High-Demand Products

If you’re selling limited-edition or high-demand products, a maximum purchase limit prevents individuals from hoarding stock, ensuring fair availability for all customers.

4. Reduce Fraudulent Purchases and Reselling

By limiting purchases, you can prevent resellers from purchasing large quantities at a discount and reselling them elsewhere.

5. Encourage Higher Average Order Value (AOV)

Setting a minimum order quantity encourages customers to buy more per transaction, increasing revenue per purchase.

How to Set Quantity Limits in WooCommerce (Without Plugins)

Step 1: Open the WooCommerce Product Editor

  1. Log in to your WordPress Dashboard.
  2. Navigate to WooCommerce > Products.
  3. Select the product you want to edit.

Step 2: Set the Minimum and Maximum Quantity

  1. Scroll to the Product Data section.
  2. Click on the Inventory tab.
  3. Locate the Stock Management options.

WooCommerce’s default settings don’t allow setting minimum and maximum order limits, but you can enforce stock restrictions using custom code (see next section) or a plugin.

How to Set Product Quantity Limits Using Custom Code

If you prefer not to use plugins, you can enforce product limits using custom code.

Add a Minimum and Maximum Quantity Restriction to the Functions.php File

Add this code snippet to your functions.php file:

php
function custom_quantity_limits( $passed, $product_id, $quantity ) { $min_quantity = 2; // Minimum purchase quantity $max_quantity = 10; // Maximum purchase quantity if ( $quantity < $min_quantity ) { wc_add_notice( 'You must purchase at least ' . $min_quantity . ' units of this product.', 'error' ); return false; } if ( $quantity > $max_quantity ) { wc_add_notice( 'You cannot purchase more than ' . $max_quantity . ' units of this product.', 'error' ); return false; } return $passed; } add_filter( 'woocommerce_add_to_cart_validation', 'custom_quantity_limits', 10, 3 );

This code ensures that customers can only order between 2 and 10 units of a product.

Best WooCommerce Plugins to Limit Product Quantity

For advanced control, WooCommerce plugins allow store owners to customize quantity limits without coding.

1. WooCommerce Min/Max Quantities Plugin

  • Set minimum and maximum order limits for specific products
  • Apply limits to categories, user roles, or product variations
  • Restrict purchases based on total cart quantity

2. Quantity Manager for WooCommerce

  • Define per-product quantity limits
  • Set step-based increments (e.g., order in multiples of 5)
  • Limit quantity based on customer roles

3. Advanced Product Quantities

  • Customize order limits based on stock levels
  • Apply purchase restrictions for new customers
  • Create bulk pricing rules

These plugins offer better flexibility compared to WooCommerce’s default settings and make it easier to enforce product restrictions.

Best Practices for Implementing Quantity Limits

1. Clearly Communicate Purchase Limits

Make sure customers know about quantity restrictions before adding products to their cart. Use:

  • Product descriptions to highlight order limits
  • Error messages at checkout if the quantity exceeds the limit

2. Use Different Limits for Different User Roles

For wholesale customers, allow higher quantity purchases, while regular customers may have lower limits.

Example:

  • Retail Customers: Max 5 units per order
  • Wholesale Buyers: Max 50 units per order

3. Combine Quantity Limits with Discounts

Encourage bulk purchases by offering discounted prices for larger quantities.

Example:

  • Buy 5+ units, get 10% off
  • Buy 10+ units, get 20% off

4. Track and Analyze Purchase Limits

Monitor customer behavior using:

  • WooCommerce Reports to analyze how limits impact sales
  • Google Analytics to track abandoned carts due to purchase restrictions

5. Use Quantity Limits for Pre-Orders and Exclusive Products

If you’re selling pre-orders or exclusive products, limit quantities per customer to ensure fair distribution.

Common Mistakes to Avoid

1. Setting Limits Too Low or Too High

If you restrict purchases too much, customers may abandon their carts. Test different limits to find the right balance.

2. Not Displaying Clear Warnings

If a customer can’t check out due to hidden quantity restrictions, they may leave your store. Show error messages before they reach checkout.

3. Applying the Same Limits to All Products

Not all products need the same limits. Set different restrictions based on demand, stock availability, and pricing strategy.

Conclusion

The WooCommerce Limit Quantity Per Product feature is an essential tool for controlling inventory, preventing stock depletion, and encouraging bulk sales. Whether you use WooCommerce’s built-in settings, custom code, or a dedicated plugin, limiting product quantities ensures better stock management and a smoother customer experience.
