Shopify volume tier discount,
per-unit pricing for bulk buyers.

A Shopify volume tier discount lets DTC brands flirt with wholesale economics — when it's applied per-unit, not per-cart. Nex Discount evaluates the Shopify volume tier discount on each product line, so larger quantities of the same SKU automatically slide into the next tier without breaking the moment a customer mixes SKUs.

    01

    A Shopify volume tier discount should apply per-line, not per-cart

    The most common Shopify volume tier discount mistake is applying the tier to the cart's total quantity. That breaks the moment a customer mixes SKUs. Nex evaluates the Shopify volume tier discount on each product line independently — 6 of one SKU and 6 of another both qualify, and each line gets its own per-unit discount.

    02

    Why the per-unit framing of a Shopify volume tier discount matters

    Shopify volume tier discounts communicate as 'save more per unit' on the storefront — that's the message that lifts AOV. It also keeps the math honest for finance: cost = (units above threshold) × (per-unit discount), which models cleanly without per-order edge cases.

    03

    Pair your Shopify volume tier discount with a wholesale gate

    A Shopify volume tier discount is a retail mechanic. Don't let it collapse your B2B program — pair the rule with a customer-tag exclusion so buyers on a wholesale contract can't double-dip. Nex's customer tag conditions handle this in one click.
