Two tools, two jobs. Get them the right way round and your menu stays small.
Variations: the same dish at a different price
A variation is a version of the dish that costs something different. Half plate and full plate. Small, medium and large. Six pieces and ten pieces.
Add variations on the dish itself, each with its own price. The order screen then asks for the size when the item is tapped, and the bill prints the size alongside the name so the kitchen and the guest agree about what was ordered.
Modifier groups: the question the cashier asks
A modifier group is the question that follows an order. How spicy? How much sugar? Any extra cheese?
Build these under Menu then Modifier groups. Each group has a rule, such as pick one and must answer, or pick up to three and optional, and options that can add to the price or add nothing. Attach the group to every dish it applies to. One sugar group can serve your whole tea and coffee section.
Why not just make more dishes?
Because a price rise means editing one dish instead of nine, your sales report tells you how many teas you sold rather than splitting them five ways, and your cashier reads a short menu instead of hunting through near-identical names.
Notes are the escape hatch
Every line on a bill takes a free-text note for the one-off request, like "no onion" or "pack separately". Use notes for the exception and modifier groups for the question you ask every day.
