Quantity rules and volume prices

A quantity rule says how a product must be ordered: a minimum (at least 12), a maximum, and an increment (in sixes). Volume prices lower the unit price as the quantity grows. Both live in B2B catalogs, so they apply to company buyers.

Set them up

1. In Shopify admin, open Products › Catalogs and open the catalog for the company location.
2. Choose a product, then set its quantity rules and volume pricing.
3. Save. Checkout applies the rules from now on.

Shopify help: Quantity rules and volume pricing

Where the theme shows them

• Beside the quantity on the product page: "Minimum 12 · multiples of 6" (Show quantity rule in Theme settings › B2B · Ordering and stock).
• On product cards: Show minimum order quantity and Show case size in the Collection, Search, Featured collection and Product recommendations sections.
• The Volume price breaks block on the product page.
• The quick-add buttons in Buy buttons, which offer the quantities that unlock a better price.

A guest has no catalog, so these usually show nothing to a guest. Use Preview the store as in Theme settings to check what a buyer sees.
