Pre-Sale Or Advance Order

Hi Folks,

I am looking at CS.cart as an option and was interested in knowing how the pre-orders actually work, pre-orders are the same as pre-paid correct?

I was curious if it is possible to switch from available on xx/xx/xxxx to available when ### quantity is on on order.

Basically I want to setup a system where I can secure a given number of quantity ordered before calling my supplier and ordering a new batch of the product.

I can't afford to keep the inventory on hand as a really small startup as the economy of scale just isn't there with small quantities.

Any help / clarifications would be greatly appreciated.
