# Buy Product Details
Completing the Buy Product details ensures products are correctly set up for purchasing & supplier management.
The **Buy Product** section of the **Add Product** form contains the information needed to set up a product for purchasing from suppliers. Completing these details helps ensure the product is correctly configured for purchasing, including its supplier, cost, and purchasing information.
This document explains how to complete the **Buy Product** section of the **Add Product** form when adding a new product to Supply’d.
***
### Completing the Buy Product Details
{% stepper %}
{% step %}
#### Open the Add Product Form
1. Select **Products** from the main menu to open the **Products** page.
2. Click the **Add +** button in the top right to open the **Add Product** form.
{% hint style="success" %}
👉 The [Adding a Product](/supplyd-erp/products/adding-products/adding-a-product.md) document provides detailed instructions on how to open this form.
{% endhint %}
***
{% endstep %}
{% step %}
#### Complete the Sections up to Buy Product
Following the guidelines for [Adding a Product](/supplyd-erp/products/adding-products/adding-a-product.md), complete the sections up to **Buy Product**.
***
{% endstep %}
{% step %}
#### Complete the Buy Product Section
Toggle on if you buy this product from a supplier.
{% hint style="warning" %}
This field will not show when **Bundled**, **Recipe**, or **Production** are selected as the **Product Type**.
{% endhint %}
Click or start typing in the **Type Supplier Name** field to view and select from your list of suppliers.
Select the supplier and click **Add**.
A form will show.
**Is Preferred?**
Select whether or not this is a preferred supplier for purchasing this product.
If set to **Yes**, the supplier will be added to your favourites, suggested first when purchasing the product, and their costs will be used for product cost calculations.
**Purchase By\* \[required]**
Select whether the item is purchased by the unit or by the carton.
**Purchase Carton Quantity\* \[required]**
Enter the number of units contained in each carton.
{% hint style="info" %}
This field is only displayed when **Carton** is selected in the **Purchase By** field.
{% endhint %}
**Buy Price (ex Tax)\* \[required]**
Enter the wholesale price for a unit or carton, excluding taxes such as GST, based on your selection in the **Purchase By** field.
**Buy Tax\* \[required]**
Select whether tax, such as GST, applies to the product when purchasing. Select **GST** (or the applicable tax), or leave blank if the product is tax-free.
**Supplier's SKU**
Enter the SKU or unique identifier the supplier uses for this product when sending orders to them. Leave blank to use the SKU assigned to the overall product.
**Supplier's Barcode**
Enter the barcode the supplier uses for this product when receiving stock. Leave blank to use the barcode assigned to the overall product.
**Supplier's Brand**
Enter the brand of the product purchased from this supplier. Leave blank if it is the same as the overall product brand. This is useful when purchasing the same product from different suppliers under different brands.
**Supplier's Size**
The weight/size of a single unit. Leave blank to ignore if the same size as the product.
{% hint style="info" %}
**Supplier's Size**
These fields control how items are tracked in Inventory and should be decided based on how you want to manage stock.
For example, with a 15 kg bag of sugar:
* If you track it as a single 15 kg bag, set **Size = 15 kg** and leave **Supplier Size** blank.
* If you track it in 1 kg units, set **Size = 1 kg** and enter **Supplier Size = 15 kg**.
Keeping this consistent helps if you switch suppliers or use multiple suppliers with different package sizes, making inventory management and reporting simpler.
{% endhint %}
{% hint style="success" %}
If you do not need a **Supplier's Size**, and you want to keep stock as simple units, leave these fields blank. The system will recognise this and track inventory in units rather than by weight or another measurement type.
This is useful when the measurement is not important, or when the item is too small for weight to be practical.
For example:
* **Cello bags** - Each bag weighs almost 0g, so tracking them by weight adds little value. It is much easier to count them as individual units for selling and production.
* **Sugar decorations for cupcakes or cookies** - These are also very light, and during production you usually count how many decorations are needed rather than weigh them. For example, you may place a specific number on each cupcake or cookie.
{% endhint %}
**Minimum Order**
The minimum order required for this supplier. You will be unable to order less than this quantity of an item. Leave blank for no minimum.
**Quantity Multiple**
The quantity multiple set for this supplier. Orders can only be placed in multiples of this amount. For example if set to "5" you will only be able to order 5, 10, 15, 20 etc. Leave blank for no order multiple.
***
{% endstep %}
{% step %}
#### Repeat
If the product is purchased from multiple suppliers, you can add additional suppliers by repeating Step 3 for each supplier.
***
{% endstep %}
{% step %}
#### Complete Remaining Fields
Complete the remainder of the form as outlined in the [Adding a Product](/supplyd-erp/products/adding-products/adding-a-product.md) document.
{% endstep %}
{% endstepper %}

## 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://help.supplyd.co/supplyd-erp/products/adding-products/buy-product-details.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.
