If everyone counts their chips when they buy in and when they cash out, and the banker does the same, it should be the rare case that the bank is short. If you do it for long enough, it will happen. The key is to not give anyone chips until they have paid the bank, even if they show up late and want to get right into the hand. A few bucks here and there is no big deal, but you don't want to be short an entire buy-in. I've had that happen once or twice.
