It allows you to sell a set of items under a single reference, while keeping traceability for each component. > **Example:** A "Workstation" kit can include a monitor, a keyboard, and a mouse, sold together at a single price. --- ## 1. Create a kit 1. Create or open a product in *Main menu > Catalog > Products*. 2. In the **Sub-products** (Product Bundles) tab, add the products that make up the kit by clicking **"Select a product"**. 3. For each component, specify the **quantity** included in the kit. As soon as a product has at least one sub-product, it is considered a kit. --- ## 2. How the kit price is calculated The **Kit pricing** block appears on the record of a kit product. It contains the **Kit price calculation mode** field, which determines how the sale price is obtained: | Mode | Behavior | | --- | --- | | **Manual entry** | The sale price **and** purchase price are **entered manually** on the kit. Kafinea **does not recalculate them** when components change. | | **Calculated from components** | The kit’s sale price **and** purchase price are **calculated automatically** as the sum of the components’ values, weighted by their quantities. | --- ## 3. Display and behavior on the kit record ### 3.1 Context banner in the *Pricing information* block An information banner appears at the top of the pricing block: - In *Manual entry* mode: "Manual entry: neither the sale price nor the purchase price is automatically recalculated from the components." - In *Calculated from components* mode: "The sale price and purchase price of this kit are calculated automatically from its components." ### 3.2 Read-only *Unit price* and *Purchase price* fields + "Calculated (kit)" badge In *Calculated from components* mode, the **Unit price** and **Purchase price** fields are displayed as **read-only** and accompanied by a **"Calculated (kit)"** badge. A tooltip specifies: *"This value is calculated automatically from the kit’s components. Switch to Manual entry mode (no recalculation) to enter it."* The kit’s purchase price directly feeds the margin calculation on quotes, orders, and invoices containing this kit. In *Manual entry* mode, both fields become editable again. ### 3.3 Automatic recalculation When the mode is *Calculated from components*, the kit’s sale price **and** purchase price are recalculated automatically in the following cases: - Adding or removing a component. - Changing a component quantity. - Changing a component’s unit price or purchase price. --- ## 4. Business rules 1. **A kit cannot be a generic product.** These two concepts are mutually exclusive. If you try to check *Generic product* on a kit, Kafinea blocks the save with the message: > *A generic product cannot be a kit.* 2. **A kit cannot be a specific product** (attached to a generic). The message displayed is: > *A specific product cannot be a kit.* 3. **A generic product cannot be added as a component of a kit.** The message displayed is: > *A generic product cannot be added as a component of a kit.* 4. **A specific product cannot be added as a component of a kit.** The message displayed is: > *A specific product (child of a generic) cannot be added as a component of a kit.* > **Note:** These rules ensure catalog consistency. Kits group "standard" products (neither generic nor specific). To manage supplier sourcing, use [generic products](https://www.kafinea.com/en/documentation/catalog/generic-products/). --- ## 5. Frequently asked questions **Why can I not check "Generic product" on my kit?** Because a kit groups concrete components with defined prices, whereas a generic product is an abstract model whose price is calculated from child specifics. The two price calculation mechanisms are incompatible. **Why are the unit price and purchase price of my kit read-only?** Because the calculation mode is *Calculated from components*. Both values are the sum of the corresponding values of its components. To enter them manually, switch the mode to *Manual entry*. **My kit price does not update after I modify a component—why?** Check that the calculation mode is *Calculated from components* and not *Manual entry*. In manual mode, neither the sale price nor the purchase price is recalculated automatically. **Can I nest kits (a kit within a kit)?** Yes, a component of a kit can itself be a kit. However, automatic recalculation does not cascade: if you modify a component of the sub-kit, the sub-kit price will be recalculated (if it is in *Calculated from components* mode), but the parent kit will not be recalculated automatically. You will need to manually modify the parent kit (for example, by removing and then re-adding the sub-kit) to trigger its recalculation. --- ## Related references 🔗 - [Products](https://www.kafinea.com/en/documentation/catalog/products/) - [Generic products](https://www.kafinea.com/en/documentation/catalog/generic-products/) - [Catalog margin analysis](https://www.kafinea.com/en/documentation/catalog/catalog-margin-analysis/)
