Systems, methods, and software products estimate cost of fulfilling an order for non-existing steel parts. A web site interacts with a customer to receive a request for quote containing a single MTO file defining the non-existing steel parts. The single MTO file is processed to generate at least one layout based upon stock information of a raw steel product. The layout defines (a) nesting of the non-existing steel parts on the raw steel product, (b) a cost of cutting the parts from the raw steel product, (c) a used portion of the raw steel product, (d) a waste portion of the raw steel product, and (e) a remaining usable portion of the raw steel product. A quote estimating the cost of fulfilling the order is generated based upon the at least one layout, and the quote is sent to the customer.
