About the Quantity Ladder
This app lets you create quantity-based discount ladders with up to 10 tiers, each setting a minimum quantity and percent off. The discount applies automatically to qualifying cart lines at checkout using a Shopify Function. You can target your quantity ladder to specific collections or products, or run it store-wide. A product-page pricing table shows customers the same discount tiers that will apply at checkout. Built for wholesale, trade and B2B sellers, it includes multi-group ladders and fail-safe protection—invalid ladders won't apply wrong discounts. Need SKU-level ladders or more groups? Enterprise options are available.
