An MVP development contract is your legal safeguard when turning an idea into working software. Without clear terms, you risk budget overruns, missed deadlines, and disputes over who owns what. Here's exactly what should be in that document before you sign.
Scope of Work and Deliverables
This is the foundation of every MVP contract. You need a detailed breakdown of what the developer will actually build—not vague language like "mobile app" but specific features, user flows, and platforms. State whether the MVP includes iOS only, Android only, or both. List core functionalities: user authentication, payment integration, database setup, or whatever applies to your project.
Include a definition of what counts as "complete." Does a feature need to be tested? Deployed to a test environment? Running in production? Be explicit. A typical MVP scope might include 5–8 core features, basic UI/UX, and deployment—nothing more.
Timeline and Milestones
Set realistic delivery dates with clear milestones. Most MVP projects run 8–16 weeks depending on complexity. Break it into phases: design (2–3 weeks), development (4–8 weeks), testing (1–2 weeks), and launch (1 week).
Include what happens if either party misses a deadline. Is there a grace period? Do delays trigger penalties, or is it just a rescheduled date? Specify how change requests affect the timeline—a new feature request could add weeks.
Budget, Payment Terms, and Change Requests
State the total cost upfront. MVP development typically ranges from $15,000 to $100,000+ depending on complexity and your location's developer rates. Clarify whether that price covers:
- Hosting setup
- Third-party API integrations
- Basic analytics setup
- Post-launch bug fixes (usually 30 days)
Define your payment schedule. Common structures include:
- 30–50% upfront, 50–70% on completion
- Monthly installments tied to milestone delivery
- 50% at kickoff, 25% at design approval, 25% at launch
Address scope creep explicitly. Any features or changes requested after contract signing should trigger a change order and additional cost. This protects both sides—you won't be surprised by surprise bills, and developers won't be expected to do free extra work.
Intellectual Property and Ownership
Clarify who owns the code and designs once you pay. You want full ownership of the final product—no licensing restrictions, no the developer retaining rights. This should state that all source code, databases, design files, and documentation transfer to you upon final payment.
If the developer uses any open-source libraries or third-party tools, document that clearly. Some frameworks (React, Flutter, Django) are free but come with specific license terms you should understand.
Technical Requirements and Standards
Specify the tech stack: which languages, frameworks, databases, and hosting platforms the developer will use. This prevents surprises where you end up with outdated or hard-to-maintain code. For example: "iOS app built in Swift using SwiftUI, backend in Node.js, database PostgreSQL on AWS."
Include testing requirements. Expect unit tests and basic end-to-end testing for core flows. Security considerations matter too—does the MVP handle user passwords, payments, or sensitive data? Specify that security best practices (HTTPS, encrypted storage, input validation) are non-negotiable.
Support and Maintenance Post-Launch
Define what happens after launch. Most contracts include 30–90 days of bug-fix support at no charge. After that, clarify hourly rates for ongoing maintenance or changes. A typical rate runs $50–150/hour depending on seniority and location.
Specify response times for critical bugs (server down, payment processor broken) versus minor issues (UI spacing, typo fixes).
Termination and Dispute Resolution
Include an exit clause. What happens if either party wants to walk away? Typically, the developer delivers what's been completed, you pay for work done, and you retain the code. Also specify how disputes get resolved—mediation, arbitration, or court jurisdiction—and whose laws govern the contract.
Frequently Asked Questions
Q: What if the MVP takes longer than expected? A: Your contract should include a change order process for scope changes that cause delays, and a realistic timeline buffer (usually 1–2 weeks) before penalties or renegotiation happen.
Q: Should I use a template or hire a lawyer? A: For MVPs under $30,000, a customized template (search "SaaS development contract template") works fine; above that, a tech lawyer review (typically $500–1,500) is worthwhile to avoid costly disputes later.
Q: How do I protect myself from abandonment? A: Require milestones with working deliverables, tie payments to completion, request the source code repository access mid-project, and choose developers with proven track records—Mercoly lets you compare and review vetted MVP developers side-by-side.
