More and more small and mid-sized businesses in Normandy are taking the leap and launching their own mobile app. Online booking, a loyalty program, a product catalog, appointment scheduling: a well-designed app becomes a genuine sales and loyalty channel, always available in your customers' pocket. But before getting started, you need to know where to begin.
The first question to ask is never technical, it's strategic: what problem does your app solve for your users? A shop that wants to sell on the go, a restaurant that wants to simplify bookings, a service business that wants to digitize appointment scheduling don't have the same needs, and therefore not the same app. Taking the time to clarify this goal avoids building unnecessary features that inflate the budget without adding value.
Next comes the specification document. List the features essential at launch (the well-known MVP, or minimum viable product) and those that can wait for version 2: authentication, push notifications, online payment, geolocation, syncing with your website or management software... Every feature adds development time, and therefore budget. A clear specification is the best guarantee of a project that stays on schedule.
Then comes the technical choice: native development (separate code for iOS and for Android) or cross-platform development with frameworks like React Native or Flutter, which let you build a single codebase for both platforms. For the vast majority of SME projects, cross-platform offers the best value: shorter timelines, simpler maintenance, controlled budget, for a result nearly identical to a native app in terms of user experience.
User experience (UX) and design (UI) deserve particular attention. A mobile app is judged within seconds: if navigation isn't intuitive, if buttons are too small, or if load times are too long, the user uninstalls it and doesn't come back. Careful mockup work, tested before development begins, avoids many costly back-and-forths once the code is written.
Development itself happens in several phases: setting up the technical architecture, building the screens and features, connecting to third-party services (payment, notifications, APIs), then a rigorous testing phase across different smartphone models before launch. Next comes publishing to the App Store and Google Play Store, which impose their own review rules and can add a few days to the schedule.
The budget for a mobile app depends directly on its complexity: a showcase app with a few static screens is nothing like an app with a user account, integrated payment, and a custom backend. That's why at La Casa de Com, every app project gets a free, personalized quote, built after a conversation about your goals, rather than a generic rate that wouldn't reflect the reality of your project.
Finally, a mobile app doesn't stop at launch. Operating systems evolve, app stores regularly impose new technical rules, and your users expect regular updates. Planning a maintenance budget from the start, even a modest one, ensures your app keeps working properly over the long term.
Launching a mobile app is a significant undertaking for a business, but it's no longer reserved for large corporations. With a clear method and a partner who understands the constraints of Normandy's small and mid-sized businesses, a professional, high-performing app is within reach of most budgets.
