Inventory

This module is for anyone who wants to maintain stock on his localhost or on website.
After you enable this module ; you have to enable the block in blocks listing page.
When the inventory block is enabled then you can select from the menu in the block as to what operation to perform.

Add a Product :-
Initially you have to register a product so that you can sale or purchase it and maintain it in stock.
Note that just adding a product won't show up in stocks listing since you have not yet purchased it.

Purchase :-
You can purchase a product from the listing of products which you have registered.
After purchasing the product it will show in the Stocks page.

Sale :-
Pretty much like purchase but here you deduct the quantity from the stock.

Stocks :-
Table listing of all the products in inventory

As this is my first drupal module and project is still not complete. I would like you guys to comment on it and ask for more functionality which you think is missing (And i am sure there is much of missing stuff :) ) . Anyways i will try to develop the module to be one stop solution for common man's inventory management.
Cheers
