Q: How much does an enterprise mobile app cost to build?
A: The cost of an enterprise mobile app, such as a field service tool or an ERP mobile extension, is driven by the number of platforms, backend integrations, offline-sync requirements, and device management needs. Cross-platform development with Flutter or React Native typically costs 30-40% less than building separate native iOS and Android apps. We provide a detailed fixed estimate after a free architect-led scoping call, with no obligation.
Q: How long does it take to launch an enterprise mobile app?
A: A production-ready cross-platform MVP typically takes 8-12 weeks from kickoff to app store submission; for reference, we shipped a production MVP in 10 weeks for WorkHire. Apps with heavy backend integration (ERP, CRM) or offline sync usually run 3-5 months. Enterprise app store review and MDM rollout add 1-2 weeks at the end, which we plan for from day one.
Q: Native or cross-platform: should we use Flutter, React Native, or Swift/Kotlin?
A: For most enterprise apps, cross-platform (Flutter or React Native) is the right call: one codebase, one team, near-native performance, and 30-40% lower cost than parallel native builds. Go native (Swift/Kotlin) only when you need deep hardware access, AR, or platform-specific UI polish that cross-platform cannot match. We recommend React Native when your team already lives in JavaScript/TypeScript, and Flutter when pixel-perfect custom UI across both platforms is the priority.
Q: How do you handle mobile security and MDM for corporate devices?
A: We build for enterprise device management from the start: compatibility with MDM/EMM platforms such as Intune and Workspace ONE, per-app VPN, certificate-based authentication, encrypted local storage, and remote-wipe-safe data handling. Authentication integrates with your identity provider (Azure AD, Okta) via OIDC/SAML. Security requirements are captured in the architecture phase, not bolted on before release.
Q: Can the app work offline for field teams with poor connectivity?
A: Yes, offline-first is standard for the field service and sales apps we build. We use local databases (SQLite, WatermelonDB, Hive) with background sync and conflict resolution, so technicians and reps keep working with no signal and data reconciles automatically when connectivity returns. The sync strategy is designed around your data model up front, because retrofitting offline support is one of the most expensive mistakes in mobile.
Q: How do you deploy apps privately to employees instead of the public app store?
A: We handle enterprise distribution end to end: Apple Business Manager with custom/unlisted app distribution or the Apple Developer Enterprise Program, and Google Play managed (private) channels for Android, plus direct MDM pushes to managed devices. Public App Store and Play Store releases are also fully managed if your app is customer-facing. You keep ownership of all developer accounts; we operate them on your behalf.
Q: Can you connect the mobile app to our ERP or CRM?
A: Yes, extending existing business systems to mobile is the core of our enterprise mobility practice. We integrate with SAP, Dynamics, Salesforce, and custom internal systems, usually through a dedicated API layer we build in Node.js/NestJS that handles authentication, caching, and offline queuing. This keeps the mobile app fast even when the underlying ERP is slow, and shields it from backend changes.
Q: What does a typical mobile project team look like?
A: A standard engagement includes 2-3 cross-platform engineers, a backend/integration engineer, and a designer for mobile UX, led by a senior engineer. Under our Guardian model, founder Deepak Jha, Technical Lead with 15+ years of experience, reviews the architecture and every release before it ships. You interact with the builders directly in your own Slack and project tools.
Q: We are a US/UK/UAE company: how do you handle timezones and communication?
A: Kosi Digital is headquartered in New Delhi, India, and works remote-first with scheduled overlap for US EST/PST, UK GMT, EU CET, and UAE GST hours. Mobile clients get builds pushed to TestFlight and Play internal tracks continuously, so stakeholders in the US, UK, Europe, UAE/Dubai, Australia, or Canada test each iteration on their own devices. Standups, demos, and escalation paths are agreed in your timezone during kickoff.
Q: Who owns the app source code and the app store listings?
A: You own 100% of the IP: source code, designs, CI pipelines, and signing certificates, and both Apple and Google developer accounts are registered in your company name. We sign an NDA as standard before any discovery work. If we part ways, you keep everything and any competent team can pick up the codebase.
Q: What about maintenance after the app ships: OS updates, store policies, crashes?
A: Mobile apps require ongoing care: annual iOS and Android OS releases, evolving store policies, and dependency updates can all break a neglected app. We offer maintenance retainers covering OS compatibility updates, crash monitoring and fixes, store compliance, and small enhancements. Most enterprise clients budget 15-20% of the initial build cost per year for this.
Q: Why hire a mobility agency instead of building an in-house mobile team?
A: An in-house mobile team means hiring iOS, Android or cross-platform, backend, and QA skills, which takes 4-6 months and rarely stays fully utilized after launch. Our dedicated team model gives you that full capability immediately and scales down to a maintenance retainer once the app is live. Many clients later hire one internal engineer whom we onboard onto the codebase we built.
