# Set up quantity rules and volume pricing
_FUBR55U5.gif) 
Leverage quantity rules and volume pricing on Shopify to establish specific quantity requirements or offer tiered price discounts for your B2B orders.
***For example:***
* If you want to sell a product in specific increments to your B2B customers or limit the quantity a customer can purchase at once, you can set [quantity rules](https://help.shopify.com/en/manual/b2b/catalogs/quantity-pricing#quantity-rules).
* If you want to offer price discounts to customers who purchase a certain quantity of a product, you can set up [volume pricing](https://help.shopify.com/en/manual/b2b/catalogs/quantity-pricing#volume-pricing).
**Quantity rules** and **Volume pricing** are managed together but can also be used independently based on your business needs.
Support for Quantity rules and Volume pricing is **available from version 8.5.0 and above**.

You can set quantity rules in the **Catalogs** section of your Shopify admin, or by [importing a CSV](https://help.shopify.com/en/manual/b2b/catalogs/creating-catalogs#export-and-import-catalogs).
**Steps:**
1. Complete the [**Initial steps**](#initial-steps).
2. Do either of the following:
* To set quantity rules for all variants of a product, hover over the product that you want to edit.
* To set quantity rules for a specific product variant:
* Click the link to the variants underneath the product name.
* Hover over the product variant that you want to edit.
3. In the **Quantity rules** column, click **+ Add**.
When the **Edit quantity rules and volume pricing** dialog displays, do the following:
* Update the **Increment** and **Minimum** fields from their default values if needed.
* *Optional:* Fill in the **Maximum** field to limit the amount of the variant that a customer can purchase in one order.
* Review the displayed values. The values might autocorrect when the quantity rules entered are invalid.
* Click **Done**.
**Note:** All quantity rules set in your catalogs apply to each product's variants independently, not to the product as a whole.
*For example:* If you set a minimum quantity rule for a product with multiple color variants, then the customer needs to purchase at least that quantity of all the same color variants.
## Set volume pricing for your products
 
You can set volume pricing in the **Catalogs** section of your Shopify admin, or by [importing a CSV](https://help.shopify.com/en/manual/b2b/catalogs/creating-catalogs#export-and-import-catalogs).
**Steps:**
1. Complete the [**Initial steps**](#initial-steps).
2. Do either of the following:
* To set volume pricing for all variants of a product, hover over the product that you want to edit.
* To set volume pricing for a specific product variant:
* Click the link to the variants underneath the product name.
* Hover over the product variant that you want to edit.
3. In the **Volume pricing** column, click **+ Add**, and when the **Edit quantity rules and volume pricing** dialog displays:
* Fill in the **Quantity** and **Price** fields for Break 1. Price break quantities must be greater than the minimum order quantity, as well as a multiple of the increment that you set in your quantity rules.
* *Optional:* To add multiple price breaks on the same product, click **Add break**, and then fill in the **Price** and **Quantity** fields for each break.
4. Click **Done**.
**Note:** All volume pricing set in your catalogs applies to each product's variants independently, not to the product as a whole.
*For example:* If you have a volume pricing set, then a customer needs to purchase the required quantity of a specific variant to meet volume pricing requirements.
