Inventory System

Inventory - : As i click on inventory, it will display all of my inventory that was added from the beggining. I will also include the a button "Add Inventory" that will allow me to add inventory. The feilds for when adding inventory are: Purchase Date, SKU, Title, Supplier, Cost Price, Quantity, Total Cost(Quantity x Cost Price). There should also be a button called "Delete Inventory" in order to delete any entry. Create sales order: From the home page, there should also be a button called "Sales Order". After clicking "Sales Orders", Software will display all of the sales that was created from beggiing until now. After clicking "Sales Orders", there should be a button "Create Sale Order". After clicking "Sale Order", i should be able to enter in sales information. Fields are: Sale Date, SKU, Title, Supplier, Cost Price(It will display cost price automatically from Inventory database as per appropriate SKU), Sale Price, Quantity Purchased(Sale Price minus Cost Price). There should also have a button to delete sales order. Reports: From the home page, there should be a button called "Reports". After clicking reports, it will display all data possible. Then i should be able to choose which data i want to display. Whether i want to display sales orders from february 01 to february 13 etc. It will will display the date in the software and i would also like to be able to export it in an excel file (.xlsx format). Updates to be done: - To add Supplier ID in "Add inventory" window. - Should be able to add multiple SKU for one Supplier ID - Supplier ID should be viewable from the inventory list - Should be able to type in SKU in create sales order window instead of dropdown option...After clicking save, if SKU does not exist in inventory, it will be promt with an error saying that SKU does not exist. - "Create Sales Order" should also have Order ID - Order ID should be viewable from the Sales List. - When create a sale for sku(B0018A) for quantity of 3, SKU(B0018A) should be reduced by 3 in inventory LIST. - Create sales order window and Add inventory window should be aligned in the middle of the screen. After project is done, i will own the software. Source code as well as executable files should be handed to me.
