Go to Website → eCommerce → Products and open the desired product. Navigate to the Sales tab and locate the Website Quantity Rules section.

Configure the Minimum Quantity, Maximum Quantity, and Quantity Step, then save the product to apply the rules on the website.

Go to the Odoo E-commerce website and open the product page. The configured minimum quantity will be automatically displayed.

Customers cannot order a quantity lower than the minimum quantity set for the product. If you do not want to apply a minimum quantity restriction, you can keep the value as 0, which is the default configuration.

When the customer clicks the plus (+) icon to increase the quantity, it will increment based on the configured quantity step.

For example, if the Minimum Quantity is 5, Maximum Quantity is 20, and Quantity Step is 5, then the allowed quantities will be 5, 10, 15, and 20. The quantity selector will increase and decrease only in increments of 5 and will not allow values outside this range.

Minimum Quantity, Maximum Quantity, and Quantity Step are configured, and the customer manually enters a quantity that does not follow the defined step (for example, entering 7 when the step is 5), the system will display a warning message. The system will not accept the invalid quantity and will automatically adjust it to the nearest valid value based on the configured step, enforcing the quantity rules on the Odoo E-commerce website.

When the customer reaches the maximum quantity and clicks the plus (+) icon, the system will display a warning message indicating that the maximum allowed quantity has been reached. The system will not allow the quantity to increase beyond the configured maximum limit.

When the customer clicks the Add to cart button, the cart page displays the products with the selected quantities.

If the customer clicks the minus (−) icon and decreases the quantity below the configured minimum quantity, the product will be automatically removed from the cart. This ensures that only valid quantities are allowed according to the Website Quantity Rules in Odoo E-commerce.

On the website cart page, when the customer clicks the plus (+) icon and the quantity reaches the configured maximum limit, the system will display a warning message such as “Maximum allowed quantity is 20.” The quantity cannot be increased beyond this limit in the Odoo E-commerce cart.

If the user manually enters a quantity such as 50 on the cart page, the system will automatically reset the quantity to the configured maximum quantity (20) defined in the Sales tab of the product. A warning message will also be displayed to inform the customer about the maximum allowed quantity in the Odoo E-commerce cart.

Pricelist Tier :

Go to Website → eCommerce → Products and open the desired product. Navigate to the Price tab and configure the required pricelist rules.

Create pricelists with quantity-based pricing tiers using Odoo’s standard configuration, specifying the appropriate price for each minimum quantity level.

On the website, the product is displayed with a minimum quantity of 5 and a unit price of 750.

When the customer increases the quantity and it reaches 10, Odoo automatically applies the corresponding bulk pricing rule from the pricelist, and the updated price is immediately shown to the user. This allows customers to clearly see the discounted price for higher quantities.

When the customer clicks Add to Cart, the system adds the product to the cart using the price determined by the selected quantity and applicable pricelist rule.
