# Fixed vs variant bundles

Choose the right bundle type based on shopper choice, pricing, and fulfilment needs.

Use **Fixed Bundles** when you want one exact set.

Use **Variant Bundles** when shoppers should choose options before adding to cart.

{% hint style="info" %}
Both bundle types fulfil as the underlying SKUs in Shopify. You keep normal picking, packing, and inventory workflows.
{% endhint %}

### Choose the right bundle fast

#### Choose Fixed Bundles if you want:

* one exact set of products every time
* the fastest add-to-cart flow
* full control over what ships together

#### Choose Variant Bundles if you want:

* shoppers to choose size, colour, scent, or flavour
* mix-and-match bundles
* one offer that works across many product options

### How each bundle type works

#### Fixed Bundles

A fixed bundle contains pre-selected items. The shopper buys the set exactly as configured.

**Example:** shampoo + conditioner in one scent.

#### Variant Bundles

A variant bundle uses selectors or slots. You define each slot. The shopper chooses the product or variant for each one.

**Example:** choose any 3 t-shirts, then pick size and colour for each item.

### What stays the same after purchase

No matter which type you choose:

* **Cart and checkout:** bundle items stay grouped together.
* **Shopify orders:** the order contains the component products and SKUs.
* **Fulfilment:** your team picks the real items, not a new bundle SKU.
* **Inventory:** stock deducts from the component products.

### Best fit by use case

#### Use Fixed Bundles for:

* starter kits
* routines
* curated gift sets
* "buy these together" offers

#### Use Variant Bundles for:

* pick-your-flavour packs
* build-your-own sets
* multi-buy offers with many variant choices
* bundles where products vary in price
