Creation:A manufacturing order is created when a request is placed for a product which has not yet been manufactured. On the other hand, a work order is completed when a customer requests a product already manufactured and in stock.
Specifications:While the manufacturing order contains the product's specifications that need to be produced, the work order includes the specifications of the required quantities and delivery dates.
Order: When a manufacturing order should be processed in the order it is received, a work order can be processed in any order.
