Wholesale Food Ordering App for Restaurant Teams

Kitchen ordering is repetitive but unforgiving: the same core products every day, from several suppliers, often for several restaurants at once, ordered in a rush at closing time. The app had to make reordering near-instant while handling exactly who — admin, manager-chef or collaborator — is allowed to order what, and where. It also had to onboard busy restaurant staff in minutes, with no desktop and no password in sight.

We chose Flutter over React Native to maximize development velocity, with Firebase powering app hosting, deployment pipelines and analytics, and all data flowing through a GraphQL API built by the client's backend team. Algolia delivers instant product search across supplier catalogs, filtered by the categories each restaurant can access — with locked categories requestable from the sales team directly in the app. Sign-in uses SMS and email one-time codes, and new users register their restaurant through a Google Places-assisted signup flow. Borrowing Slack's workspace paradigm, users switch between their restaurants in one tap, governed by role-based access control — admins, manager-chefs and collaborators — with invite-by-phone onboarding that assigns roles automatically. An order cockpit tracks active shipments along their routes alongside order history and downloads, while usual lists turn the daily reorder into a few seconds' work. A document viewer surfaces the restaurant's administrative records — bank details (RIB), SIRET number and KBIS documents — and a built-in concierge channel connects teams to customer service. The app keeps evolving through evolutive maintenance packages of 48 to 60 hours.
