I buy the equipment in a different order than you do: I upgrade the shoes (2), I upgrade the dough maker (3), I do nothing (4), I upgrade the oven (5), I upgrade the cutting board (6), I upgrade the shoes again (7), and I buy a second cutting board and a second dough maker (

. So I have one upgraded oven, one upgraded cutting board, and one upgraded dough maker and one cutting board and one dough maker that are not upgraded (as well as twice upgraded shoes). You want to use the upgraded equipment for the bigger pizzas and the pizzas with more toppings since the upgraded equipment is faster. You really don't need the second oven at this point: the topped pizzas sit on the cutting boards while the oven is full, but I always get full tips.
The overall order of the pizzas are 1-2-4-4-2-1-1-2-4-4-4
The first three pizzas are a whole pizza with three toppings, a half with two toppings, and a quarter with one topping. I put the whole pizza on the upgraded cutting board and start topping it; when the half pizza is ready I put it on the regular cutting board (which is slower), so the whole pizza gets topped before the half pizza is done. When the whole goes in the oven, I prepare the quarter pizza, which has only one topping.
Then there are two more pizzas (a quarter and a half that both need to be topped), but those aren't a problem since the others are cooking.
As I remember, the tricky part concerns the next three pizzas: first you have two full pizzas (and the dough takes a while to make), so you want to be sure that the dough is being made while you are topping the previous two pizzas. (If you forget and see the first whole pizza with one topping in a customer's order, push the button for the second whole pizza at that point). Also, when the first whole pizza comes out of the dough maker, be sure to push the button for the half pizza that follows the two whole pizzas because it has three toppings, which get put on while you cook the first whole pizza (which has one topping) and then the second whole pizza (which is plain).
The rest of the pizzas are all 1/4 pizzas with two toppings, and they can get a little tricky because, as I remember, sometimes they are the same, but usually two pizzas have the same two toppings but the third has a different two toppings. After this round, I upgrade the second cutting board.
It really helps to know the order AND to know which pizzas get three toppings because you don't even have to see the order to start topping a pizza with three toppings. You have to see the orders for 1 and 2 toppings because they change every time you play the game.
By the way, the tricky (or, at least, unnerving) part of level 10 is that it starts when three customers appear at the same time asking for three 1/4 pizzas--the first has two toppings, the second is plain, and the third has three toppings. Start making the one with three toppings, then the one with two toppings, and then (as the first two finish), put the plain pizza in the oven, followed by the 2-topping pizza, and the 3-topping pizza in the oven (getting, of course, the orders of the new customers as you zip up and down; remember to dart over and start the doughmakers with the next pizzas....). The rest of that level isn't too hard.
Anyway, I hope that this explanation helps, and good luck!
