UMS = one unified menu at Manage Group. Price per country via Working Country. Stores merchandize after Sync Items — they don't invent a second catalog.
The cast
Menu section — category heading (Burgers, Drinks).
Item config — product family (not priced yet).
Variant config — what customers buy: photo, name; one variant can hold multiple region prices (one per country).
Modifier — choice group (pick your sauce).
Option — one choice inside a modifier.
Store item — live on the store menu = synced Item Config + Variant Config.
Working Country & multi-country prices
Before pricing: Manage Group → Settings → Working Country (which country/currency you are configuring).
Add a price for that country on the Variant Config; switch Working Country to price another market on the same Variant Config.
Sync Items for stores in country X only shows variants that have a price for X — otherwise they are invisible in that country's Sync Items tab.
Group vs store job
Group / UMS — build and price the unified menu once (managers).
Store — merchandising: hours, QR, Menu du Jour, section/item order, availability overrides, Live orders.
Group managers can do everything store partners can on every store, plus UMS + People.
