Maybe I'm using the term "accounting" a bit loosely. It's not the accountants job to monitor day-to-day cashflow, that's more a bookkeeper's or manager's job. If they're crooked, it's a bit harder to catch (especially if they are able to offset cash losses with by opening secret a line of credit with a supplier).
I'm pretty sure my Canadian accountant would be quite upset at your conclusion. Cash disappearing has nothing at all to do with accounting.
