# Configure and add weighed items
A weighed item is an item whose sale price in POS is determined by its weight. Weighed items may also have an associated tare weight. This topic describes all steps required to set up weighed items in RMH.
## Enable POS to read random weight EAN and UPC codes
It is recommended that you enable both random weight EAN and UPC barcodes in the store rules. This ensures that POS can read random weight barcodes.
1. Click **File** | **Configuration**.
2. Click **Store Rules**.
3. Expand **POS Options**.
4. Select the following options:
* **Utilize random weight EAN codes**
* **Utilize random weight UPC codes**
5. Click **Save And Close**.
## (Optional) Configure predefined tares
Some items that are sold by weight may be sold in packages, such as clamshell containers, that have an associated tare weight. When this is the case, you must set up the tare and assign it to the weighed item so the tare weight can be deducted from the item weight at the point-of-sale to determine the correct item price.
1. Click **Setup**.
2. Expand **Merchandising**.
3. Click **Tares**.
4. To add a new tare, click **New**.
5. In the **Label** field, enter the name or description of the tare.
6. Enter one of the following:
* **Fixed:** A fixed value to subtract from the item's measured weight as the tare weight.
* **Percent:** A percentage of the item's measured weight to subtract as the tare weight.
7. Click **Save And Close**.
## Add weighed items
This procedure describes how to set up items where the weight will be entered at point-of-sale, either by weighing the item with an integrated scale or by manually entering the weight into POS.
{% hint style="info" %}
The store may sell other items whose sale price is determined by weight, such as packaged meats, that do not have to be weighed at point-of-sale. These items can be set up with the Standard item type rather than the Weighed item type.
{% endhint %}
1. Click **Merchandising**.
2. Click **Items**.
3. Click **New**.
4. Select **Standard Item** and click **OK**.
5. On the **General** tab, enter the following:
1. For the **Item Lookup Code**, enter either a 12-digit UPC-A or 13-digit EAN-13 barcode for the item.
2. From **Barcode**, select either **UPCA** or **EAN13**.
3. From **Item type**, select **Weighed**.
4. Enter the item **Price**.
5. Enter the item **Cost** (e.g., cost per unit of weight, such as gram, kilogram, ounce, pound, etc.).
6. (Optional) On the **Tare Weights** tab:
1. Select a predefined tare from the grid. You can select multiple predefined tares if the item may be sold in different containers with different tare weights.
2. (Optional) Select **Allow Open Tare** if you want the cashier to select the container or manually enter the tare weight in POS. If desired, select **Open Tare Rounding** to round tares up to a whole number.
{% hint style="info" %}
If the tare weight is unique to this item (i.e., it is not used by other items), select **Fixed Tare Weight** and enter either a fixed weight or percentage.
{% endhint %}
7. Enter other item information, as required.
8. Click **Save And Close**.

## 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://docs.rmhpos.com/store-manager/manage-items/weighed-items/setting-up-weighed-items.md?ask=&goal=
```
`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.
