I know different bakers use different serving size charts or even create their own. I'm just trying to get an idea of what is most commonly used. If you were making a 3 tier cake to serve 100 (Including top tier in servings) would you use:
6, 9, 12 or 6, 10, 14 ?
I use the 6/10/14 and charge them for 128 servings. I don't own any odd size pans (no 9's, 15's, etc.)
Indy, go buy some fricken pans for crying out loud. Stick the cost on one of those detailed spread sheets of yours--you will make it back in no time.
You're doing fondant and scratch.
Now you can do odd cakes too. 
While you're in a buying mood--get some cheese for hubby's macaroni too, poor baby!!!

Oh come on! That would be THREE NEW THINGS in a single year! I can't take it, I tell ya, I can't take it! Don't make me!

Now now it'll be ok. You can wait till next quarter if you want but you are just delaying being able to plan a cake easier. But I do feel your pain.
You shoulda said,
"But Kate I don't wanna make odd cakes like yours.
Anyway--just attempting some humor.
Come on now Debi.... that little shell of yours has to explode sometime right??
