I need you to develop some software for me. I would like this software to be developed for Windows. A production system that the operator will enter how much raw material will be used on a specific day to produce certain products and an estimation of the quantity of products produced daily/monthly/yearly.
An order system, when entering an order from the clients, the system must print a receipt and a invoice order (optional for the operator) that will go directly to the general inventory and warehouse. There should be a payment option (cash, credit card [payment number], cheque [payment number] and deposit number) and an option for currier (shipping information, must print the client information after receiving the order).
Sale system, when performing a sale there should be a payment option (cash, credit card [payment number], cheque [payment number] and deposit number), with its own client database.
Purchase/expenses system, when buying and receiving raw material, with its own supplier database. A return and replacement system.
At the end of the day the program must create a spreadsheet of all the items produced/sold with its costs.
All the systems must be tied with the general inventory.
