Miva Merchant only tracks Inventory at the product level. You can not enter quantities for different product types, i.e. you can not define the amount of green t-shirts and the amount of red t-shirts. Instead, you enter the total amount of t-shirts.
However, Order Manager allows Inventory Tracking at the Attribute level.
There are two (2) possible solutions that allow you to track Inventory at the Attribute level in your Miva store:
list products separately
use a third-party solution
