On clicking the add new rule button, a form appears on the page with the following options:

3. Increment unit quantity for sell: Set the incremental unit by which the quantity will increment on each customer click.

You can add sell unit for multiple products at once through a CSV file. In a CSV file, you need to enter increment unit, minimum, and maximum quantities against product id and combination. Once, you have entered all these details in a CSV file, you can upload it under the Upload CSV tab.

As per the rule, the option to select a quantity less than 2 is not possible for the customer. If a customer selects a quantity less than 2, then a warning popup will display on the product page as shown in the below screenshot.

A similar kind of popup will also display on the page when a customer selects a quantity greater than the set quantity i.e. 8.

Additionally, here is a GIF to let you understand how this minimum incremental unit functionality works for the customer.

You can view in the following GIF that a customer is only able to select a quantity in multiples of 2. This is because the minimum increment quantity has been set as 2 while creating the rule.

Also, the customer cannot select a quantity less than 2 & greater than 8.

Apart from the rule, you can also set increment quantity, maximum quantity, and minimum quantity for sale on individual products.

Go to catalog -> products -> edit product. Click on the configure button under the modules tab.

Firstly, enable the settings to proceed.

After enabling the setting, you can set the increment, minimum, and maximum quantity for sale.

Kindly note, that if you applying a sale setting on the product and the same product comes under the sell unit rule, then the priority will be given to the individual product setting.

As per the settings, you can view in the following GIF that a customer is able to select a quantity in multiples of 3 only.

Also, a warning message will display on the product page if a customer selects the quantity less than 3 and greater than 3.

Thus, a customer will now be able to select a quantity as per the rule. Here, in this case, a quantity in multiples of 3 & minimum & maximum quantity as 3 & 9.

The process to order the product will be as per the standard PrestaShop procedure.

Note: Product quantity box will be allowed for customer input only when the sell in multiple of quantities feature is disabled or the minimum quantity is set as 1.
