　　The main problem with the argument is that the conclusion is based upon insufficient evidence. The fact that some of Windfall’s purchasing invoices contained errors might simply be attributable to the sloppy accounting practices of Windfall’s suppliers. Thus, rather than indicating a general problem, the invoice errors might simply be indicative of a problem that is specific to Windfall Ltd. In other words, the evidence drawn from Windfall’s experience is insufficient to support the conclusion that all purchasing invoices are subject to similar errors.

　　Secondly, the evidence offered in the argument suggests only that companies purchasing from the same suppliers that Windfall purchases from are likely to experience similar problems. If the firm’s clients do not purchase from Windfall’s suppliers, checking for errors might turn out to be a monumental waste of time.
