Set up quantity tiers

Quantity tiers give a discount based on the number of units a customer buys.

How quantity is counted

Choose the Discount method when creating the rule:

Method	What counts as "1 unit"
Same variant	Only the exact same product variant (e.g. only Size M Red counts toward the tier)
Mix variants	Any variant of the same product (e.g. Size M + Size L of the same shirt = 2 units)
Mix products	Any product covered by the rule (e.g. shirt + pants = 2 units)

Example: A customer buys 3× Size M and 4× Size L of the same shirt (total 7 units).

• With Same variant: neither reaches a tier of 5+ (largest is 4)
• With Mix variants: the 7 units together reach a 5+ tier
• With Mix products: all products in the rule count together

Setting up tiers

1. In your volume pricing rule, click Add tier
2. Set Min quantity (e.g. 10)
3. Set Max quantity (e.g. 49) — or leave blank for "50 and above"
4. Choose discount type and value
5. Repeat for additional tiers
6. Save

Tiers must not overlap. The app applies the highest matching tier.

Example

Min	Max	Discount
3	9	5% off
10	49	10% off

A customer buying 12 units gets 10% off. A customer buying 2 units gets no discount.
