### 1. Introduction

A **kit product** is a product in Novulo composed of one or more other products.  
The components can be:

- **Inventory products** (physical goods)

- **Services**

- Or a combination of both

Kit products are common in many industries:

- **Retail:** Smartphone + smartwatch, camera body + lens, table + set of chairs

- **IT & hosting:** Virtual machine + additional CPU + OS license

- **Insurance:** Car insurance with coverage for liability, theft, and collision damage

Manufacturers often market kits as standalone products, complete with their own EAN/UPC, packaging, and promotional campaigns.

### 1a. How kit products are identified in Novulo

In the Novulo reference architecture, whether a product is a kit is indicated by the feature:

- **`N_Product.N_Is kit (fx)`** — a Yes/No function feature

The original implementation of this is in **M3391 (Novulo Products)**, where the product type is selected from a dropdown with options like:

- Service

- Item (inventory product)

- Kit

- Generic

When **“Kit”** is selected, the feature `N_Is kit (fx)` returns **Yes** ; otherwise, it returns **No**.

If needed, this selection mechanism can be enhanced or customized in alternative component implementations to support more complex or simplified product classifications.

### 2. How kit products work in Novulo

- Kits are defined at the product level, listing each component and its quantity.

- Physical stock is only kept for the **inventory components** — not for the kit itself.

- When purchasing and receiving a kit, the system can **automatically split it into components** in stock.

- When selling a kit, Novulo determines availability based on the components’ stock.

* * *

### 3. Availability calculation

- Kit availability follows the **limiting factor** rule: the component with the lowest available stock determines how many kits can be sold.

- This applies whether the kit contains only physical products, only services, or a mix.

Example:  
Kit: Camera body + lens

- Camera body stock: 15 units

- Lens stock: 8 units  
**Kit availability:** 8 units

* * *

### 4. Performance considerations

- Novulo can calculate available stock for kits in real time.

- This works fine for internal use (e.g., sales screens, back-office reporting).

- For **high-speed external feeds** (webshops, marketplaces, API integrations), this calculation can be too slow — especially when you have many kits and complex component structures.

* * *

### 5. Kits & Publishable Stock

- When **publishable stock** is enabled, Novulo pre-calculates the safe-to-promise quantity for kits as well as regular products.

- This is much faster for feeding external channels.

- Important: **Do not sum publishable stock for kit products when calculating total inventory** — kit stock is based on the same components as other products, so totals will be inflated.

For more on how publishable stock works, see Publishable Stock in Novulo ERP.

### 6. Best practices

- Use kits when products are marketed and sold together but tracked in stock separately.

- Avoid creating duplicate stock records for kits.

- Use publishable stock for external feeds if you have a large number of kits.

- Always check that kit component availability logic matches your business rules (e.g., allow substitutions or not).
