One other suggestion, if you're having to outfit a whole shop: Look at discounted gift cards. I personally use (and sell) on Raise.com, where Lowe's gift cards go for a pretty steady 8-9% off of their face value.
This is pretty far out of most bookkeepers' comfort zone, so I'd talk to them well in advance to handle their (legitimate) concerns before trying this. But if you can swing it, it might save you a couple hundred bucks over the season between shop equipment and hardware for the build.
(
Oh, and they have pizza cards too.)
