# Item MarketPlace: Amazon

How would you use CanCan features to build a marketplace just like Amazon ?

To build an app like that you would need the following features:

* The ability to list products that users can buy
* The ability to have third party merchants apply to list products on your app
* The ability to have third party merchants list and sell products on your app
* The ability to take a percentage off of every sale made by third party merchants
* The ability to rate and/or review products/sellers/clients

## List products that users can buy

You can read about how to list products on your CanCan channel on the page below

[listing-products-services](https://docs.payswap.org/products/cancan/products-services/listing-products-services)
{% endcontent-ref %}

## Have third party merchants apply to list products on your app

You can setup your CanCan channel so that you would be able to receive partnership applications from third party merchants.

You can read about how to do this on the page below:

## Have third party merchants list and sell products on your app

## Take a percentage off of every sale made by third parties

When listing their products on their partner walls, users will specify the percentage they are willing to give you off of each sale they make. In the image below, the user entered 10 in the referrer fee field meaning he/she will be giving you 10% on each sale.

We can also see that the minimum fee allowed by the channel is 0%. You can change this parameter by following the guide on the page below under the **Updating The Minimum Partnership Fee** section
