# 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  |
| 50  | *(unlimited)* | 15% off  |

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