# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://orbit-b2b.gitbook.io/orbit-b2b-docs/volume-pricing/quantity-tiers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
