How to manage stock control for product variants?

Hi, Looking for some help on an issue we are having:

We have setup various variants for our products… eg. buy 1 / buy 2 and save 10% / buy 3 and save 15%.. all done by variants so they can be picked / bought from the main product page.

We are now having issues on how to controle the stock properly of the product, eg if someone buys “3 and save 15%” how do we decrease the stock by 3, rather then 1?

Thanks!

Hi Dan

Is each variant a version of the main product e.g variant 2 is the 10% off containing two units? If this is how it has been done there is no easy way to control stock (theme customisation to add the correct individual units to cart or a system outside of Shopify to see the combined variant SKU and ship the correct individual units).

You could possibly use https://help.shopify.com/en/manual/discounts/discount-types/buy-x-get-y and also apply for combined discounts https://help.shopify.com/en/manual/discounts/combining-discounts so you can run more than one at a time.

The other way to do this is via Shopify Scripts https://help.shopify.com/en/manual/checkout-settings/script-editor/examples/line-item-scripts#tiered-product-discount-by-quantity and then display something on the product page to communicate the offer.

Cheers
