Arithmetic/Mathematical Values in Modifiers

[earthdiego]

This is a feature that Aloha POS has had for ages.

Use case: Shot Pours, Doubles, etc.

Situation: Guest asks for a double whiskey. Standard double whiskey pour is 3oz (two portions of a 1.5oz serving size)

Problems:

• The only way to ring in a double to indicate via KDS or printed ticket to the bartender is to ring in the whiskey twice, and either creating a $0 value double button or manually typing in "double" as a note to indicate that the guest has ordered a double and that is not two separate orders.
• The way we are using "Neat" (or "rocks)  modifier is to make it a $2 up-charge. The problem with this is that not all spirits are priced the same. For instance if there was a spirit that costs $100 to the guest, each 0.5 oz is worth $25. The difference between a standard pour ($100, 1.5oz) and a neat/rocks pour ($125, 2oz) is $25 whereas a drink that costs $10 to the guest obviously would be way less.

Solution: Allow mathematical values in the price input for modifiers.

Examples:

• Double Modifier: [ *2  ] -- this will take the price and multiply by 2
• Shot Modifier: [  /2. ] -- this will take the price and divide by 2
• Neat Modifier:[  ((x*0.25)/1.5)  ] -- this will calculate the ratio to increase the price per 0.25oz

Of course there can be buttons to make this step more user friendly such as a button to replace a value X with "item price" or use common symbols such as "%"

Other solution could be to have an option where you can designate Fluid Oz/Milliliter values for Standard Pour / Neat Pour / Rocks Pour / Shot Pour and have default built-in modifiers provided by toast that creates the calculation.

I believe the first solution would be the most flexible with perhaps even a way to toggle "advanced mode" so standard users cannot access it unless prompted.

You can use pre modifiers for this with a multiplication factor. The only problem is with reporting, that is sometimes an issue for some people when it comes to inventory tracking. It would be nice to just allow math on modifier pricing.

This is quite literally the reason that we need this. I am using craftable as inventory management but also pull reports via toast. We need to be able to see reports on modifiers as well.

When we used FuturePOS they set up all of our Liquor Mods based on shelf and those mods would be assigned to the each liquor - Shot, double, etc.  They were plus or minus $1.00 for example.  So if a Crown Royal cocktail (soda/coke/sprite) was $7.00 but a shot was $6.00 -  a "-1.00 mod SHOT"  was attached to that liquor.  It was very detailed.  But that was back in the day when trainers came on site, installed and trained.  When we went to Toast we simplified it all and we are manually making adjustments when needed.
