The costly restaurant mistakes happen in the gaps between your apps
Rented restaurant software handles the sale well and the hand-offs badly, and the hand-offs are where food, labor and guests get lost.
Inventory and ordering: counts live on a clipboard or a spreadsheet, the order guide lives in a supplier portal, and the chef places orders from memory and a quick look at the walk-in.
Catering and private events: the inquiry comes by email or phone, the deposit sits in one tool and the menu in a document, and the kitchen finds out only if someone remembers to tell it.
Staff scheduling across locations: each manager builds a schedule alone, without seeing the event booked at a sister location or the cook there who wants extra shifts.
Menu data across delivery apps: prices, descriptions, add-ons and sold-out items are edited by hand in each app, so they drift apart and guests order dishes you stopped serving.
