Curious - How much emphasis do you put on verifying and tabulating the orders for your major fundraiser(s)?

I tend to believe that every order should be recorded and verified against the money sent in. We usually find some errors, but mostly it's a way to count, cross-check, and protect ourselves. Plus we can use the data to calculate all kinds of (meaningless!!?) statistics. To make it easier, we have developed a set of forms (order log, check log, etc.). I'd like to hear how other PTO's do it. Are we crazy?
