Set a per-item amount for each quantity on each variant, such as 12.44 each from 5 and 10.11 each from 10. Enter tiers in the app, or read the metafields your ERP, PIM or sync already writes, with editing turned off. A Shopify Function applies the tier in the cart and at checkout, and checks minimum quantities and pack sizes there too. Missing or invalid data is ignored at checkout. Showing tiers on product pages needs a theme edit: the app doesn't change your theme.

• Set a per-item amount for each quantity, with a preview of the customer's total
• Read tiers from your own metafields or ones an ERP or sync writes
• Read-only mode when another system manages your tiers
• Enforce minimum order quantities and pack sizes at checkout
• Separate tiers while a variant is on sale, and your own checkout wording
