Epan production application provides a management which starts from raw material and reaches to desired product by the best method.
The basic flow of production application goes like this, you receive an order with item[s], as soon as you approve that order a job card is created, a job card travels through different departments changing it's status from received to completed, and at last the product is dispatched to the customer.
For those item[s] which are already present in stock there is no production process involved and they can be directly dispatched.
If any production process is outsourced by your company then it can also be managed under epan production application.
