Cost & Timeline

What enterprise buyers ask about budget and delivery speed.

Enterprise mobile app development typically costs between $15,000 and $500,000 or more, depending on complexity, platform count, integrations, and compliance requirements. A simple single-platform MVP sits at the lower end of that range, while a multi-platform enterprise app with custom backend systems, security certifications, and offline sync sits at the higher end. Cost is driven mainly by the number of user roles, third-party integrations, and the level of security and compliance work required, not just screen count. See our engagement models for how pricing structures map to different project types.

Timelines generally range from 8-12 weeks for a simple MVP, 4-6 months for a medium-complexity app, and 6-12+ months for an enterprise-grade product, as general industry ranges. The variation comes from the number of platforms, backend complexity, third-party integrations, and compliance review cycles. A phased approach, shipping a core MVP first and layering in features afterward, is the most reliable way to hit the shorter end of these ranges.

An MVP (Minimum Viable Product) is the smallest version of an app that delivers real value to users and lets a team validate demand before investing further, while a full product build is the complete feature set planned for long-term scale. MVPs typically focus on one core user journey, one platform, and the minimum backend needed to support it. A full build adds secondary features, multi-platform support, advanced integrations, and the hardening needed for production scale.

Yes, building an MVP first is almost always cheaper in total cost of ownership because it validates the core idea before larger budgets are committed to features users may not need. An MVP narrows scope to the single most important user journey, which reduces design, engineering, and QA time. Feedback from real users after MVP launch then directs which full-product features are actually worth building, avoiding wasted spend on unused functionality.

Platforms & Technology

What buyers ask about iOS, Android, and AI capabilities.

Choose native development when the app needs deep hardware access, maximum performance, or platform-specific UI, and choose cross-platform frameworks like Flutter or React Native when speed to market and one shared codebase across iOS and Android matter more. Cross-platform typically reduces engineering time and cost since one codebase serves both platforms. Native remains the stronger choice for apps with heavy graphics, AR/VR, or complex background processing needs. See our iOS vs Android build guide for a deeper comparison.

iOS development targets a smaller set of Apple devices using Swift and a stricter App Store review process, while Android development covers a much wider range of device manufacturers and OS versions using Kotlin, with a more flexible Play Store review process. This means iOS testing is more predictable across fewer device configurations, while Android requires broader device and OS-version testing. Release cycles also differ: Apple's review can take longer, while Play Store updates typically go live faster. Read more in our iOS vs Android guide.

Yes, AI features such as personalization engines, chat copilots, document intelligence, and predictive workflows can be built directly into a mobile app's backend and connected to the client through standard APIs. This typically involves integrating an LLM or custom model behind a secure API layer, then surfacing results through the app's existing UI. The scope of AI work depends on whether the feature needs real-time inference, offline capability, or access to proprietary enterprise data. See AI + GenAI Solutions for our approach.

Security & Compliance

What regulated and enterprise buyers ask about data protection.

Compliance is handled through security controls built into the engineering process itself: encrypted data at rest and in transit, access controls, audit logging, and documented data-handling policies aligned to HIPAA, GDPR, and SOC 2/ISO frameworks. These controls are scoped during discovery based on which regulations apply to the client's industry and geography. Ongoing compliance also requires monitoring, periodic review, and a named point of accountability on both sides of the engagement. See Security & Compliance and the Trust Center for details.

The client owns all code, designs, and intellectual property produced during the engagement once final payment is made, as set out in the project agreement. This includes source code, documentation, and any custom assets created specifically for the project. Third-party libraries and open-source components used within the app retain their own original licenses, which are disclosed as part of delivery.

Data privacy requirements are scoped to the applicable regional framework: US clients are typically aligned to HIPAA, CCPA, or SOC 2 depending on industry, while European clients are aligned to GDPR, including data residency and lawful basis for processing. Architecture decisions, such as where data is stored and how it is transferred, are shaped by these regional rules from the discovery phase onward. The right framework depends on where the end users are located, not just where the company is headquartered. See Security & Compliance for our controls.

Working With Zetrixweb

What buyers ask before starting an engagement.

Zetrixweb offers three core engagement models: a Dedicated Squad starting from $1,000/month for ongoing product work, Fixed Scope projects starting from $5,000/project for defined deliverables, and Specialist Support starting from $15/hour for targeted, flexible help. The right model depends on whether the work is open-ended product development, a bounded project with clear milestones, or short-term specialist capacity. Teams can move between models as the engagement's needs change. Full details are on our Engagement Models page.

Yes, delivery teams are structured to provide meaningful working-hours overlap with both US and European time zones for standups, reviews, and stakeholder communication. Overlap windows are agreed during onboarding based on the client's core hours. This keeps decision-making and QA feedback loops fast regardless of where the client team is based.

Getting started begins with a discovery conversation through the Partnership Gateway, where scope, timeline, and the right engagement model are discussed before any commitment is made. That conversation typically covers current stage of the product, target platforms, compliance needs, and budget range. From there, a proposal and a recommended engagement model are shared before work begins. Start at the Partnership Gateway.
