Programme for Working with Goods

The task is to create the most simple program in which people of any age will be able to manage the goods in the green pharmacy. The program should allow you to add the income of the goods, sell the goods, add the goods to the catalogue, change the price and name of the goods, view the remains of the goods in the warehouse, create reports for the arbitrary date, write the goods, carry out the inventory of the goods (recount) and many other additional functions. Likewise, all operations of the administrator must be performed from any computer, from any point of the world, and all operations of the seller - only from the room of the pharmacy.
The program was implemented in 2 weeks, all the wishes of the customer were taken into account. HTML/CSS, PHP, minimum JavaScript and well-optimized, indexed SQL databases have been used, making data sampling operations happen quite quickly.
