Multiple item quantity options from one main inventory?

[northwoodspets]

Hi -

I sell feeder insects for reptiles. I buy the insects in bulk and then give customers the options to purchase them in various quantities. I need the main bulk amount reduced by the various quantities as they are purchased.

Example:

I buy 1000 crickets.

I offer them in quantities of 100, 250 & 500.

Right now I have each quantity package set up as individual items.

I need the main stock of 1000 crickets to be reduced by the quantity purchased i.e. if one customer buys item #201 of 100 crickets, I now have 900 in stock then the next customer buys item #202 of 250 crickets I would then have 650 in stock.

The problem is I can't give all items 1000 crickets in inventory.

How can I set things up to have multiple items reducing the main inventory? Is there a way to set up options of the same item so the customer picks the quantity they want from a drop down list or something?

Thanks!

Hi @northwoodspets

Inventory is tracked on a per-item basis, so each item that you create will need to have its own inventory amount assigned to it. 

Unfortunately there isn't really a way to have a master inventory that reduces based on a bundle item. 

While item #202 may indicate that 250 crickets were sold, only the inventory of item #202 will be reduced.
