Child & Parent items - How do I use component inventory in the UI?

JTPets — Sun, 21 Sep 2025 16:30:36 GMT

How can I do this in retail? I found it in the API but not sure how to do it in the UI
https://developer.squareup.com/docs/inventory-api/enable-stock-conversion

I want to sell a case of something for cheaper than individual items.

1 want to sell items, like chicken feet, they come in a bag of 55 units, if i have 115 individual units in stock you should be able to buy 2 cases at a reduce price, without me having to create a coupon everytime

And vice versa, if i have 2 full cases i can sell 60 individual units

Hi @JTPets , thanks for posting 🙂.

I'm playing around on my test account to see the best way to achieve this. Can you confirm if you'd want to apply a different price when your customers purchase 1 case or 2 cases at once?

Single unit would he different and whole cases would be different but I don't think I need a 3rd price

Thanks for clarifying @JTPets .

You can create a new unit directly when creating your item (or beforehand in Items > Units) .

Sign in to your Square Dashboard and click Items & orders > Items.
Select an existing item or create a new one.
Scroll down to Unit and click on Add Unit. Select a unit and set the precision.
Enter the unit cost under Variations.
Click Save.

I also took a screencast so it's easier to follow.
