Our website sells thousands of items, mainly bulk to distributors, and our inventory changes frequently.
I am trying to find an APP that we designate a Minimum Quantity on Products using a TAG they need to purchase, example this being 24. Example, adding in "MIN24" in a product would enforce the minimum to purchase is 24, in increments of 24. If the stock quantity goes under the 24 threshold, then the APP should automatically be using increments of 1 instead of 24 as the new minimum, overriding the TAG that is set. There are certain products that we like to keep always at increments of 1 that would bypass any rule. So, you just wouldn't put a TAG in the product since the Default is 1. This rule should also be highly enforced in the Cart so they are unable to alter the number lower than the 24 threshold.
Some APP's I see, you have to maintain each and every item individually with a quantity.... and if the inventory falls below 24, you have to KNOW to go back into the APP and change the increment to 1 so people can actually buy the item, otherwise it will say you can't. Doing that to thousands of items is just way too time consuming.
