I’m desperately seeking a way to prevent all of our products from reaching below a threshold of x2-3 quantity. Need to implement a safety stock buffer, basically.
I am NOT looking to add cart limits or individual/grouped product limits – what I need is for the front end to prevent a client from being able to add any more quantity of a product to their cart IF said product is at the qty threshold we’ve set.
Seems like all the accessible apps I can find are only half-functional in the sense that the mechanism is strictly based on cart limits, which is not what I’m looking for – we need an app that specifically blocks a buyer from adding more copies of a product to their cart ONLY if the product is at 2 or less in stock. Suggestions for apps to achieve this ?
This sounds something that can be handled with custom code as well, So check if the available quantity is 2 or less than that than hide or disable the atc button and plus button to stop users from adding more
I’m looking for an automated solution, hence posting in 3rd party app thread. We have thousands of product variety–checking stock counts daily / manually coding each product page & keeping up with it like that is not an feasible option
Hi @kittenpix 
For reserved inventory, buffer stock, etc see unavailable inventory state :
https://help.shopify.com/en/manual/products/inventory/fundamentals/inventory-states#unavailable
yes it’s an incredibly dumb and confusing shopify calls it inventory “unavailable” on the merchant sid but that’s just shopify doing what shopify does and mangling tihngs into blurry concepts instead of what devs get like safety_stock

Backend inventory apps that can modify inventory or automations to work with the inventory api directly is prolly the way to go prolly, e.g. mechanic

Most apps are built with max cart items in mind not buffers.
But this can be done as an advanced theme customization of business logic you wouldn’t be updating theme pages when done properly you would be setting criteria in product/variant mfs or metaobjects etc.
Reach out to me to get something like that built.
For multichannel you’d combined it with an app that uses shopify-functions to prevent api/multichannel checkouts with improper checkout quantities ; possibly the validation functions but that just stops checkout it wont mutate quantities.
Hard fix do this literally and just remove the excess inventory from the inventory, storing the value of the excess amount else where where you do some sort of reconciliation on a fixed schedule so everyone understand when/why/where inventory has gone too.
Reach out if you need to do any of this and can’t find an off the shelf solution.
I may be misunderstanding exactly what it is you’re trying to accomplish, but I would think this could be done simply with some simple editing of the product form file. Specifically creating your own custom logic for the quantity selector and/or add to cart button. And maybe some additional Javascript that looks at inventory and does whatever math you’re looking for. You could code it to do whatever you want. Hide it, make it non-functional, greyed out, or whatever. Since you specifically don’t want a standard cart limit app.
You are probably right. But as I understand your situation you don’t really have to code for each product page since each product page follow a single template unless you created others. So you just update the code once to the template being used for your products.
But yes, you will need to check for inventory, so it will stop users form adding more to cart when that number is reached in your example 2 or less. But as I write this I am thinking you will anyway have to update inventory for your products, so yeah it’s not problem actually, atleast from what I understand. May be I am not getting the full picture.
