how to manage one stock with same multiples items bundle

[krmb]

Hello everyone,

I would like to ask you a question about stock management on Shopify.
I have a stock of A products with 100 items
on my product page I'm selling 3 variants of product A
A1: 1 item
A2: 2 items
A3: 3 items
On my product page my stocks are therefore :
A1 : 100
A2 : 50
A3 : 33

When a customer buys A1, I would like the stock to be deducted by 1 unit in all variants, so A1: 99, A2: 49, A3: 33 (because 33x3=99),
Basically, I'd like any variant purchased to be deducted from the stock of all the other variants because the stock is common to all 3 variants.

I've tried channelup/bundleup but the application causes quite a few bugs when it modifies the orders.

Do you have a solution please?

thank you

Hi @krmb 

Yes, you need a custom APP which will allow to map variant I'd with product quantity.

Mapping will allow you to update sync quantity to all the variant or product from one location.

Let me know if you are willing to hire for this.
