# Setup: Configure inventory and availability rules

Norce has a built-in availability model that is used to provide accurate and relevant availability information for eCommerce storefronts. Norce takes data from WMS or ERP systems and build up a structure of data based on the products and warehouses and locations.

The model is configurable so that it is possible to give different data depending on which application or market who asks.

## Required steps

- Create client and at least one application
- Create a product classification structure, specifically the product types.
- Set up a price list structure for each market/application used.


## Preparations

To set up all the availability structure there are some questions you need to know the answer for:

- Understand the client logistic model and how it should be used by online business.
- What kind of information will be provided and how to map it into Norce model.
- The client's preference of how to display availability online.


## How-to

- Go to [warehouse tab](https://norce-open-demo.admin-se.playground.norce.tech/product/warehouse/warehouse) and set up each warehouse with location needed.
- Configure [Connected warehouses](https://norce-open-demo.admin-se.playground.norce.tech/pricing/pricelist) on each price list.
- Decide on how to display availability and implement it on the storefront application. See some examples [here](/solution-portal/detailed-design/availability-structure#about-interpreting-availability-data).

### Further configuration

It is possible to add extra fields on onhand records as info types. This can be handy if you want, for example to send in more information about the availability, that is not just an in-stock *value*. See more about it [here](/solution-portal/detailed-design/extend-availability).

- Add [ProductOnHand](https://norce-open-demo.admin-se.playground.norce.tech/product/settings/infotypes/onhand) info types


Note also the [client settings](/user-portal/settings/client-settings), specifically

- **Use on hand subtraction**, which sets up reservation functionality.
