Need a recommendation on inventory management woocommerce plugin

I need to find an inventory solution to a problem Im sure others have but not sure how to solve.

I have a product, lets say I have 100 units of ProductA. If you buy them in bulk, say 25x, you get a discount.

The default solution though is that you can set a price and an inventory available on that "25x" but it acts like a different product than just 100 units of ProductA.

I need it so that if I tell woocommerce we have 100 units total of ProductA, someone can buy either:

100 units(/quantity) for $1 each

25x only 4 times for $.75 each

50x only 2 times for $.50 each

Does that make sense? Is this possible. Basically bundles pricing
