# Kit Product Sync

Learn how kit products and their components are downloaded from Shopify to HotWax Commerce.

#### Kit products setup in HotWax Commerce

HotWax suggests that retailers set up kit products in Shopify as individual products with their SKUs, just like any other item. Even though these kits are made up of several components, Shopify treats them as a single product.

HotWax downloads kit products and their components like regular products through the `Sync Shopify Product Updates` job and uses integration with [ERP systems](https://github.com/hotwax/oms-documentation/tree/user-guides-pub/documents/learn-netsuite/integration-flows/kit-products.md) to identify the components that make up each kit.

#### Manage kit products with the Bundles app and HotWax

Shopify retailers often use apps like Bundles to sell kit products by linking their components (products included in a kit) from Shopify’s product catalog. The Bundles app creates kits by adding the component SKUs to a metafield on the bundle product.

HotWax imports these kit products and their components through the `Sync Shopify Product Updates` job and reads the metafields to understand the relationship between kits and their components. A job runs to check if a product includes components. If the product is identified as a kit, it is categorized as `MARKETING_PKG_PICK` in HotWax. This links the components (as separate SKUs) to make sure they are reserved and fulfilled together when the kit is ordered.

Bundles app has its [drawbacks](https://docs.hotwax.co/documents/learn-shopify/additional-resources/kit-products) when it comes to determining inventory for multi-location fulfillment.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.hotwax.co/documents/learn-shopify/shopify-reference/products/download-kit-products.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
