Hey, I am a new developer who wants to use Zen Cart.

I am going to be using it for a real-estate, deed shopping.

Meaning that there will only be 1 given quantity of each item or deed I list. Is this possible to do with Zen Cart? Also if someone purchases the deed, will it automatically remove or update the site to reflect 0 inventory instead of inventory of 1?

Also, I need two purchasing options. One pay up front, and another to be able to hold the inventory?

Is Zen cart this flexible and can anyone help me out? I would truly appreciate it.

Thanks
