Option set for pizza sizes, different modifier prices for each size

[scottiespizza]

I've been selling only one size pizza (18") for 9 years, using Square the whole time, and I'm getting ready to add a small 10" pizza option. Thankfully Square's features have expanded quite a bit over the last decade, and so I was pleased to find that I can easily create a Pizza Size option set for "Large 18-inch" and "Personal 10-inch", allowing me to charge different prices for the two sizes of the same item with a simple drop down for online customers.

However, I can't figure out the best way to configure my toppings modifiers so that I can have different prices for toppings based on the selected pizza size. I've searched around here and I'm not seeing anything posted about this since years ago, so I thought I'd raise the issue again, hoping that Square has made some advancements since it's been aware of the need for many years.

I did some googling and found that Toast has this feature available: https://central.toasttab.com/s/article/Setting-Up-Using-Menu-Modifier-Pricing-Features-for-Your-Menu 

How does it work with Square?

What I would really prefer NOT to do is force my online ordering customers to scroll through multiple lists of the same pizza items in different sizes, or a huge list of modifiers for different sizes trusting that they won't order a "Large" pizza and choose a "Small" topping.  

Thanks!

With Square's built in features for item modifiers - I don't see how someone could order a LG pie and select SM or Personal Toppings.   Seems with either Square's POS App or Square for Restaurants, you should be able to have LG toppings associated with a LG pie and small toppings associated with a SM or Personal pie.  Or perhaps I'm missing something, if so I'm sure that another volunteer Community Member has some thoughts.

Thanks @JK_Fiber_Art, I feel like that *should* be the case, but I'm having trouble finding a clear path to setting that up, so that Small and Large are an option under a single item, with aptly priced toppings for each size, rather than having a menu twice as long due to the same items being listed separately for different sizes.

Here's an example of what the ideal setup would be:

Category: Pizza

Item: Margherita Pizza

Size Option: Small ($15) or Large ($20)

Toppings Modifier: Pepperoni ($2 for small, or $3 for Large)

So that a customer's online ordering flow is Margherita Pizza > Large > Add Pepperoni, and the final item price is $23.

If anyone knows how to do this I'd greatly appreciate some guidance!

I'm also trying to figure this out.  Can you please elaborate?  At the moment, I have sizes as options but cant figure out how to link different modifiers to each size. Right now, all modifiers show up for the item.  I.e.

Cheese Pizza

Option - Size: S, M, L

Modifiers - Toppings (s), Toppings (M), Toppings (L)

All 3 toppings modifiers show up on the item display page.  So customers can decide to select L pizza size and choose to select Toppings (s) instead of using the dropdown for Toppings (L).

How is everyone getting the number of pizzas to order under said pizza with out creating a ton of modifiers?
