# Why are the tier prices not applied in my quotation?

[Tier prices ](https://support.robaws.com/en/article/tier-prices-1qiz3c/)are prices that are determined by the **quantity** the customer buys.  You set these on the item record.
Even so, it can happen that the tier prices are not applied straight away in a quotation.  Below you will find the possible causes, each with an example to clarify.  

*In our example the price is € 100 for 1 tin of paint and € 90 from 5 units onwards.*

## Tier prices in a simple quotation

In a simple quotation the tier prices are determined **per line**.  So if you show the same item several times on the quotation, the quantities are **not added together** to arrive at a tier price.
When you add an item, the correct (quantity discount) price is visible immediately.

## Tier prices in a calculated quotation

In a calculated quotation the tier prices are calculated **across the whole quotation**.  If the same item appears several times on the quotation, including in the line details, the quantities are **added together **to calculate the correct tier price.

To calculate the correct tier prices, ${color}[#fb0404](**click the 'update prices' button**).  This makes sure that all quantities are added together and that the correct tier prices are applied.

*In the example below the quotation consists of 2 lines:*
* *line 1 = 1 tin of paint *
* *line 2 = a post with 0.10 tins of paint per m² in the line details -> quotation for 200 m² -> 20 tins of paint*
*BEFORE update prices the tier price is not yet applied, so the price is € 100.  *
*As soon as the 'update prices' button is clicked, the quantities for this item from the whole quotation are added together, so that the tier price of € 90 is applied on line 1 as well as on line 2.*
