A gift set of three. One thing to buy, three things on the shelf, and that
gap is where the counting goes wrong.

## Two ways to hold one

**As its own product.** You make the sets up in advance and count them like
anything else. Simple, and the components leave your count when you build
them.

**As a linked bundle.** Shopify sells one line and takes stock from each
component's [inventory item](https://storestandards.com/glossary/inventory-item/). Nothing is made up
in advance, and availability follows whichever component is shortest.

The first suits a Christmas set you assemble once. The second suits a bundle
that is really just a discount.

## Pick before you launch

Switching later means recounting both the bundle and every component on the
same day, with selling stopped.

## Where it goes wrong

A bundle is built as its own product and the components are never deducted.
You now have twelve sets on the shelf and Shopify still thinks it has all
thirty-six items that went into them, so
[stock accuracy](https://storestandards.com/glossary/stock-accuracy/) drops on four lines at once.

The other one is a bundle sold at a good discount that quietly clears your
fastest [variant](https://storestandards.com/glossary/variant/). The set sells, the component runs out,
and the line that was funding the shop is gone for three weeks.

- [Variant](https://storestandards.com/glossary/variant/): A variant is one buyable version of a Shopify product, such as the blue medium. Stock, price and barcode all live on the variant.
- [Inventory item](https://storestandards.com/glossary/inventory-item/): An inventory item is the countable half of a variant. Stock levels attach to it, one per location, not to the variant itself.
- [Stock accuracy](https://storestandards.com/glossary/stock-accuracy/): Stock accuracy is how often the number on screen matches the number on the shelf, counted line by line rather than in total.
