stock inventory

this file has been created by me from maybe two years ago, it helps me entering data about the company's products and raw materials stock and sales in and out, like if we produce one product we put like we produce 40 cans of one product, and if any customer come and buy lets say 10 cans , there is one sheet that shows final stock of this product ,, result will be 30.

names of products and material has been changed due to company privacy.
