Statement of Work
Ref: 2026-001 • Standard Business Template
Overview
This agreement stipulates that all source code, design assets, and intellectual property remain the sole property of the Developer until the final project milestone is paid in full. Upon receipt of final payment, a non-exclusive, perpetual license or full ownership transfer—as defined in the specific payment schedule—will be granted to the Client. Any additional features, platform updates (e.g., new iOS/Android versions), or third-party API changes requested after the signing of this document will be treated as a separate Change Order and billed at the Developer's standard hourly rate.
The Developer’s liability is strictly limited to the total sum of fees paid under this agreement. The Developer shall not be held liable for any indirect, consequential, or incidental damages, including but not limited to loss of data, loss of revenue, or security breaches resulting from third-party hosting or external library vulnerabilities. It is the Client's responsibility to provide all necessary API keys, store credentials, and third-party account access required for the successful deployment and maintenance of the application.
Third-Party API Deprecation
If Firebase, Stripe, or a specialized SDK updates their requirements mid-build, you could spend dozens of hours refactoring code that was already finished.
App Store Review Purgatory
Clients often blame developers for business-related rejections, such as Apple's 4.2 Minimum Functionality rule, leading to payment delays.
Hardware Fragmentation
Without specific constraints, a client may expect a complex UI to perform identically on a flagship iPhone and a low-end tablet from 2019.
What is a Mobile App Developer Contract?
A Mobile App Developer Contract template is a professional agreement covering software scope, platform requirements, and intellectual property rights. It protects developers by defining supported OS versions, limiting liability for store rejections, and setting clear payment milestones tied to specific deliverables like source code and production binaries.
Built from real freelance projects
This template is based on real-world scenarios across freelance projects where unclear scope, missing payment terms, and revision creep led to lost revenue. It is designed to protect your time, define expectations, and ensure you get paid.
Why Mobile App Developers need a clear contract
Mobile development is uniquely volatile due to the involvement of third party gatekeepers like Apple and Google. Unlike web development, a mobile app requires specific provisioning, certificates, and strict adherence to evolving store guidelines. A contract ensures the client understands that 'launch' is often dependent on third party approval, not just your code. It explicitly defines which physical devices are supported, preventing the client from demanding a perfect experience on an obscure five year old budget Android phone. Without a written agreement, the line between a bug and a feature request becomes blurred during the User Acceptance Testing phase. It also protects your intellectual property by defining exactly when the source code transfer occurs, usually only after the final milestone payment is cleared in your bank account.
Real-world scenario
A developer agrees to build a 'simple' social app for $10,000 on a handshake deal. Three months in, the client sees a new feature in TikTok and demands a similar video filtering tool, claiming it is part of any social app. Because there is no signed scope of work, the developer feels pressured to comply to get paid. Just as the app is ready, Apple releases a new iOS version that changes how location permissions work. The developer spends another week fixing the app for the new OS. The client then refuses to pay the final $5,000 because the app is 'delayed' and they want it tested on five different iPad models that were never discussed. The developer has now worked 300 hours for a project that should have taken 120, effectively losing money on the engagement while the client holds the final payment hostage over features that were never part of the original price.
🛡️ What this contract covers:
- ✓Phase 1: High-fidelity UI/UX wireframes and technical architecture documentation
- ✓Phase 2: Development of the Minimum Viable Product (MVP) including frontend, backend API integration, and alpha testing
- ✓Phase 3: Final cross-platform debugging, App Store and Google Play Store submission, and transfer of the production source code
Best practices for Mobile App Developers
Define Device Tiers
Explicitly list the specific hardware and OS versions used for QA testing to avoid endless optimization requests.
Account Ownership
Require the client to purchase their own developer licenses so they own the relationship with Apple and Google from day one.
Change Request Process
Establish a formal process where any feature not in the original spec requires a signed addendum and an additional invoice.

Frequently Asked Questions
What happens if the App Store or Google Play rejects the app?
The developer will address any technical bugs or non-compliance issues related to the original scope, but is not responsible for rejections based on subjective editorial decisions or changes in platform policy during development.
