Kits and Bundles

Kits & bundles

A kit is an item defined as an assembly of other items — a repair kit, a starter bundle, a product you build from components. Gubbins tracks what a kit is made of and works out how many you could build from the stock you currently hold.

Where to find it: the Kit tab of an item's details, once the Kits & bundles capability is enabled (Modular UI).

Defining a kit

On an item's Kit tab, list the component items and how many of each the kit needs:

"Starter electronics kit" = 1 × breadboard + 10 × jumper wires + 5 × LEDs + 2 × resist600 packs.

Gubbins then shows a live "how many can I build?" figure, calculated from the current stock of every component — so you can see at a glance whether you can fulfil an order or need to restock a part first.

💡 Tip The buildable count updates as component stock changes, so a kit doubles as an early warning: if you can suddenly only build one, a component has run low. Pair it with reorder points on the components.

Kits vs the other groupings

ℹ️ Note A kit is made of other items. That's different from:

• Variants & SKUs — the same product in different sizes/colours.
• Related items — items that work with each other.
• Projects & BOM — a one-off build with its own bill of materials and budget, rather than a reusable kit definition.
