This gives you practical and flexible control over the number of products in your store.  So, if you want to manage bulk orders, sell individual units, or enhance the shopping experience for your customers, this plugin provides clear and user-friendly solutions and helps you prevent customers from ordering too few or too many times.

So, in this article I’ll walk you through how to install this plugin and how to use it in a simple way.

Let’s get started!

Step1:

➡ Download the Plugin

To get started, you will need to download the “WooCommerce Quantity Manager – Min Max Step Quantities Plugin” plugin, which gives you the flexibility to control product quantities through simple steps.

After downloading the plugin from your WPFactory account, upload it to your WordPress site.

Step2:

➡ Access the Plugin 

Once the plugin is installed and activated, you can tailor it to fit your business needs.

​Go to WordPress dashboard > WPFactory > “Quantity Manager”.

Step3:

➡ General

These general settings apply to the entire store.

• Enable plugin

First thing, you should activate the plugin to control product quantities on your store.

• Decimal quantities

This option allows you to use decimal numbers in the min/max, and quantity step.

Example: If you want the customer to buy 0.5, 1.5, or 2.5 kilos → set Step = 0.5

• Decimal quantities in admin order

This option allows the store management to handle orders with decimal quantities from the backend. It is useful if you sell products by weight or measurement.

• Sold individually

If you want to sell only one piece of the product per customer, the “Sold individually” option allows you to sell a single item of the product to each customer (Without the possibility of increasing the quantity).

This option is useful for exclusive or limited products.

• Change minimum quantity

When you enable this option, it will change the minimum for all products to 1.

This option applies to: 

• Simple products.

• Grouped products.

• Cart items.

Note:  It will be ignored if you have enabled the Minimum Quantity settings in a separate section.

• “Add to cart” validation

By this option, you can specify how the system should behave if the customer enters an incorrect quantity.

Options: 

Do not validate → No validation, accepts any number.

Round → Rounds the number to the nearest integer according to the specified step.

Step auto-correct → Automatically adjusts the quantity to match the step value.

For example: If Step = 5 and the customer entered 7 → the system adjusts it to 5 or 10 depending on the settings.

• Cart notices

If the customer reaches the cart with the wrong quantity, an error message or alert will be shown.

Enable → Enable messages

Cart notice type → Specify message type (error or alert)

• Block checkout page

If you enable this option, it will prevent the customer from accessing the payment page if the quantities are incorrect.

Useful for avoiding orders that violate the rules.

Quantity on archive pages

• Enable quantity on archive pages

This option allows the customer to select the quantity and add it to the cart directly from:

• The shop page

• Category pages

• Archives

Note: Works only with simple products. 

Useful for speeding up purchases, especially in wholesale stores.

Language Guide

If your store is multilingual, you can use shortcodes to display different messages depending on the language.

Initial Quantity Options

From here, you can choose which number appears as soon as you open the product page.

• Single product page: Set the default quantity on the product page.
• Archive pages: Set the default quantity on store pages or categories.

Useful if you want the quantity to start, for example, at 5 instead of 1.

Step4:

➡Minimum Quantity

This section is dedicated to managing the minimum quantity, whether at the product level, cart, category, or even attributes.

• Minimum quantity

When you enable this option, it activates the minimum quantity control system in the store.

• Add to cart button

If the stock is below the set minimum → hide the “Add to cart” button.

Useful if you don’t want the customer to ask for a smaller quantity than required.

Hide quantity input

If the quantity in the stock is equal to the minimum → the quantity input field is hidden.

This means the customer buys only the available quantity without any modifications.

You can hide the quantity field from certain places:

• Product page: Hide it from the product page.
• Cart: Hide it from the cart page.
• Loop: Hide it from the shop, categories, and tags page.

Useful if you want to set specific quantities without allowing the option to modify them.

Cart Total Minimum Quantity Options

(Minimum total basket)

This option sets a minimum total number of products in the cart, regardless of the number of different products.

For example: An order can only be completed if the total number of items in the cart is at least 20.

• Cart total quantity

This is where the required number is specified

• Message

You can customize the error message using:

%min_cart_total_quantity% → the required minimum

%cart_total_quantity% → the current quantity in the cart

Example: 

Minimum allowed order quantity is 20. Your current order quantity is 12.

Per Item Minimum Quantity Options

From here, you can set the minimum limit for each product.

• All products

If you put a number here → all products must be sold at this minimum (separately, not combined).

For example:
Each product must be purchased with a minimum of 5 pieces.

• Per product

If you do it:

– A Meta Box will appear within the edit page of each product.
– You can set a different Minimum for each product.

Very useful if each product has a different quantity policy.

• Messages

You can specify the error message using:

• %product_title%

• %min_per_item_quantity%

• %item_quantity%

Example:

Minimum allowed quantity for T-Shirt is 5. Your current item quantity is 2.

• Allow selling below minimum quantity if stock < min.

If you enable this option, if the stock is below the minimum → it allows selling the remaining quantity.

Useful when the product is about to run out, and you want to sell the rest instead of letting it sit.

• Allow all products

Saves the settings on all simple products at once.

• Run save “below stock meta”

When activated, the “Sell below Minimum’ setting applies to all products.

Per Category Minimum Quantity Options

(Minimum according to classification)

When activated, new fields are added within the edit page of each category.

You can set:

– A minimum for each product within this category
– Or a minimum for the total products of this category in the cart

• Messages

The message can be customized using:

• %category_title%

• %min_per_item_quantity%

• %item_quantity%

Example:

Minimum allowed quantity for category Shoes is 10.

Useful for wholesale stores according to category.

Per Attribute Minimum Quantity Options

(Minimum according to specifications – such as color or size)

It works in the same way as categories.

But the difference:

You can choose certain attributes instead of applying them to everyone.

Example:

All products in size ‘XL’ must be sold in a minimum of 3.

• Message

• %attribute_title%

• %min_per_item_quantity%

• %item_quantity%

 

Step5:

➡Maximum Quantity

These settings allow you to set the maximum quantity of products a customer can purchase in your store, whether at the product, category, or cart level.

When you enable this feature, it allows you to activate the maximum quantity section.

• Cart Total Maximum Quantity Options

This section allows you to set the maximum quantity of products at the cart level, regardless of the number of products in it.

The message can be customized to show the customer what the maximum limit is and how much they have currently requested.

• Per Item Maximum Quantity Options

This option allows you to set the maximum for each product individually, rather than for their total.

Per Product Feature (Pro Feature): You can set a limit for each product individually. When enabled, a field appears on the product edit page to set the limit for each product.

• Per Category Maximum Quantity Options

When activated, it adds two fields to each category page:

1.To set the limit for all products in the category.

 

2.To set the limit for all products in the category combined in the cart.

• Per Attribute Maximum Quantity Options

It works in the same way as the class maximum, but it can be applied to specific properties like color or size instead of applying it to all properties at once.

 

➡ Important Notes

• To display the maximum quantity as soon as the product page loads, you need to set the option from General > Initial Quantity Options to Max quantity.

• If the default product quantity is higher than the maximum, the quantity will automatically be set to the maximum when the page loads.

Step6:

➡Default Quantity 

These settings allow you to set a default quantity for the product when the page loads, instead of the default number 1, so that this quantity is automatically displayed to the customer when they open the product page.

 

• Default quantity

You can enable the section to set a default quantity for all products when the page loads.

Example: Instead of showing the number 1, you can display the number 2 or 3 as the default quantity.

• Per Item Default Quantity Options

From here, you can set a default quantity for all products at once.

Per Product Feature (Pro Feature): You can set a default quantity for each product individually. When enabled, a field appears on the product edit page to specify its default quantity.

• Per Category Default Quantity Options

When enabled, a new field is added to each category page, allowing you to set a default quantity that applies to all products within that category.

This makes it easier to manage default quantities for large categories without needing to adjust each product individually.

Step7:

➡Quantity Step

These settings allow you to specify the increase or decrease when pressing the -/+ buttons in the quantity field. This feature is often used with the minimum quantity, especially if you sell products in specific units.

Example: If you sell bottles in sets of 6, you must specify:

-Step = 6
-Minimum = 6

And if you leave the minimum as 1, the quantities will become 1, 7, 13… and so on, which causes a problem.

• Cart Total Quantity Step Options

This feature ensures that each item in the cart increases or decreases by the specified value, regardless of the quantities of individual products.

Very useful for stores that sell products in fixed pack sizes (such as packs containing 10 units).

• Per Item Quantity Step Options

You can set a quantity step for all products at once.

Per Product Feature (Pro Feature): You can set a quantity step for each product individually. When enabled, a field appears on the product edit page to specify its quantity step.

Additional options:

1. Allow changing the step if the stock is less than twice the step value.
2. Allow adding the entire remaining quantity in stock after the last multiple of the step.

• Per Category Step Quantity Options

When activated, a field appears on the page of each category to set the quantity step for all products within that category.

• Per Attribute Step Quantity Options

It works the same way as the class, but it can be applied to specific properties like color or size instead of applying it to all properties at once.
