Overview

Modifiers are the add-ons a customer picks with a menu item: extra cheese, no onions, large size. On their own they add price. When linked to ingredients, they also deduct stock automatically — so an “Extra Cheese” modifier drops your cheese stock every time it’s ordered.

Modifier Groups

Manage groups (Sides, Size, Extras) and their options.

Links

Audit view: every modifier option and the ingredient(s) it deducts.

​
Linking a modifier to an ingredient

1

Open Inventory → Modifiers

Switch to the Modifier Groups view.
2

Pick a group and option

E.g. Group “Extras” → Option “Extra Cheese”.
3

Add ingredient link

Click Add ingredient. Select ingredient (Cheddar), enter quantity (30g), confirm unit.
4

Set deduct_quantity

Almost always true. Set to false only when the modifier changes price but not stock (e.g. “No cheese”).
5

Save

The link is active. Selling this modifier will now deduct 30g of Cheddar per order.

​
deduct_quantity semantics

Negative modifiers (“No onions”, “Sauce on side”) normally set deduct_quantity=false because they change preparation but don’t remove ingredients from stock — the recipe already deducted onions.

​
Multi-ingredient modifiers

A single modifier can link to multiple ingredients. E.g. “Family Upgrade” adds 2 chicken pieces, 200g chips, and 1 drink. Every sale deducts all three.

​
Tips

  • Audit the Links view monthly — modifiers get added, but links often forgotten.
  • Match modifier units to ingredient units (ingredient in kg → modifier in kg or g via conversion).
  • Test after linking: place a test order with the modifier, check Adjustments for the auto-deduction.
  • Use modifier groups for size upgrades so quantity scales linearly.

​
Common mistakes

  • No ingredient link. Modifier priced but stock unaffected — quietly loses margin visibility.
  • deduct_quantity=true on a negative modifier. Removes ingredients that were never added.
  • Double-counting via recipe and modifier. If a burger recipe already includes cheese and “Extra Cheese” also links to cheese, you deduct twice — which is correct. But confirm the intent.
  • Wrong unit. Ingredient in kg, modifier in g without converting — severe over-deduction.
