Software Development Agreement for an MVP: Example and Key Clauses
An MVP development agreement sets out what the team will build, how the client will accept and pay for each milestone, who owns the deliverables, and what happens if the project ends early. This guide uses a U.S. mobile app project to show how those terms fit together.

TL;DR
A strong MVP agreement does three jobs: it defines "done," ties payment to milestones, and settles ownership and risk before any code is written, as Story LLP puts it.
Scope lives in a detailed statement of work (SOW), not in "build an app." Acceptance criteria must be testable.
Under U.S. copyright law, ownership generally starts with the author. Use a signed written assignment to specify what copyright transfers to the client and when.
A written change-order process protects both sides from scope creep, especially on fixed-price work.
Plan post-launch support in the contract itself, not after launch.
What an MVP development agreement actually does
An MVP is the smallest version of your product that can test a real market assumption. The contract behind it has to be just as focused. Sprintlaw describes a software development agreement as the contract between a client and a developer that sets the terms for building, customizing and maintaining software, including mobile apps.
Most agreements cover the same core ground. Story LLP lists scope and SOW, change control, payment, acceptance, IP assignment, background IP, confidentiality, warranty, liability, open source and termination. A KTS Law practice note adds staffing, insurance, non-solicitation and indemnification to the typical list.
For a founder, the agreement is the shared definition of the project. It gives both sides a reference for scope, decisions and invoices.
Example agreement outline for an MVP
Here is a working skeleton you can compare against any draft. The right-hand column shows what a good version of each section does.
Section | What it should say for an MVP |
|---|---|
Parties and recitals | Who is contracting, and the product goal in one or two sentences |
Statement of work (Exhibit A) | Features, platforms, integrations, design deliverables, out-of-scope list |
Milestones and schedule | Named deliverables with target dates and the payment tied to each |
Acceptance | Objective criteria, a review window, a cure cycle for rejected work |
Fees and expenses | Pricing model, deposit, milestone invoices, pre-approved expenses |
Change control | Written request, written impact on fee and schedule, approval before work |
IP ownership | Assignment of code and designs, carve-out and license for background IP |
Confidentiality | Covers trade secrets and customer data, survives termination |
Open source and third parties | Disclosure of components and their licenses |
Warranty and liability | Defect-correction period, liability cap with stated exclusions |
Support and maintenance | Post-launch terms and optional support packages |
Termination | Exit triggers, handover of code and design files, and transfer of account ownership or administrator access |
The rest of this article takes these sections in the order that causes the most disputes.
Scope and the statement of work
Vague scope is the single most common source of friction. Sprintlaw advises spelling out what the developer will deliver, ideally in a detailed specification or SOW, and avoiding descriptions like "build an app."
A useful SOW for an MVP includes:
Target platforms: iOS, Android, or both, and whether the build is native or cross-platform (for example Flutter or React Native).
Feature list: each feature written as a user story with its own acceptance criteria.
Design deliverables: user flows, wireframes, clickable prototype, final UI files.
Integrations: payments, analytics, authentication, third-party APIs.
Out of scope: an explicit list of things the MVP will not include, such as an admin dashboard or a second language.
Environments and hand-off: staging, production, app store submission responsibilities.
One structural detail matters more than it looks. Captain Legal's guidance recommends attaching the SOW as an exhibit incorporated by reference, with an order of precedence, so a sales deck cannot quietly expand the scope.
If your MVP also includes a public product page, put web specifics in the technical spec too. For example, SoftwareApplication schema markup is the kind of deliverable that is easy to forget unless it is written down.
Pro Tip: Write the out-of-scope list together with the in-scope list. Every item you name as "not now" is one fewer argument later, and it forces the MVP discipline that keeps budgets and timelines intact. Our MVP roadmap guide shows how to decide what goes on each side.
Milestones and acceptance criteria
Milestones turn a long project into checkpoints. For fixed-price work, Captain Legal recommends tying payments to named deliverables and defining objective acceptance criteria, a testing window and a period to correct rejected work.
Objective means testable. For a login feature, “User can log in” leaves the conditions for passing unclear. Specify that a registered user can sign in with a valid email and password and reach the home screen, and that an incorrect password returns an error. Terms.Law also outlines the review process, from delivery notice and defect reporting through correction, deemed acceptance if agreed, and the payment trigger.
An example milestone schedule for a typical MVP might look like this:
Milestone | Deliverable | Acceptance test |
|---|---|---|
1. Discovery and design | Flows, wireframes, clickable prototype | Founder sign-off on each core flow |
2. Core build | Sign-up, main feature, backend | Each user story passes its written criteria on staging |
3. Beta | Feature-complete build in TestFlight and Google Play internal testing | Open defects within the agreed severity threshold |
4. Store submission | Release builds and required store assets | Builds and assets are submitted to the agreed stores, and submission is documented |
If approval or release is also part of the engagement, state who handles review feedback and how a delay from Apple or Google affects the schedule and payment.
If the agreement includes deemed acceptance, missing the review deadline may mean the milestone is treated as accepted. The developer may then invoice if the agreement makes deemed acceptance a billing trigger. Name a primary and backup reviewer, and put the review deadline on the calendar.
Fees, payment milestones and expenses
MVP work is usually priced either time-and-materials or fixed-price. The KTS Law checklist notes that a payment section should state payment methods, when payment is due (for example 30 days from invoice), interest on overdue balances and collection costs, and should address ancillary costs such as out-of-pocket expenses, training and maintenance.
An illustrative fixed-price schedule could bill 30% at signing, 40% on acceptance of the beta build and 30% on acceptance of the store submission and any other agreed final deliverables. Define the acceptance criteria for each billed milestone and specify when each invoice is payable. Sprintlaw recommends tying payments to milestones and deliverables.
Choose percentages that reflect the risk and effort in your project. The signed agreement sets the actual amounts and due dates.
What to check in this section:
Pricing model: fixed-price gives you budget certainty if the SOW is tight. Time-and-materials gives flexibility if you expect the product to change, ideally with a cap or regular budget reporting.
Expenses: third-party fees such as app store accounts, cloud hosting, paid APIs and design assets should be listed, with pre-approval above a set amount.
Late payment terms: know the interest rate and what happens to work in progress if an invoice is disputed.

Who owns the code and designs
Under U.S. law, copyright generally starts with the author. Commissioned work qualifies as work made for hire only in limited circumstances. For custom deliverables the client is meant to own, specify which rights the developer assigns in a signed writing and when the transfer takes effect.
An IP clause should address the following.
Designate deliverables as works made for hire to the extent permitted by law.
Include a written assignment of the agreed rights in the custom deliverables, with a clear effective trigger such as receipt of payment for the applicable milestone.
Identify the developer’s pre-existing tools and reusable libraries as background IP. Specify the license the client needs to use that IP as part of the product, including the rights to maintain, modify and distribute the product and have another provider support it.
Require the developer to secure the necessary rights from employees and subcontractors so it can make the agreed assignment and grant the agreed license.
Identify who owns and administers the code repository, cloud hosting, app store and analytics accounts. Use each platform’s supported process to transfer ownership or grant administrator access as agreed.
An assignment transfers ownership of the specified rights. A license gives the client permission to use the covered IP within the agreed terms.
Confidentiality belongs next to IP. Sprintlaw recommends protecting confidential information, trade secrets and customer data, with obligations that survive the end of the contract. If you are sharing the idea before signing, read our checklist on what to check in an app development NDA, and see our five IP protections for app contracts for the wider picture.
Change control: how scope moves without a fight
An MVP will change once real users or investors see it. The contract should assume that and give change a lane. Freibrun Law describes a written mechanism for requesting, approving and implementing changes, in which the developer responds in writing with the effect on fee and schedule and is not obliged to proceed until both sides agree on the impact and revised specifications.
The same source stresses that this matters most in fixed-price projects: without a written process, scope changes can turn into open-ended arguments about whether extra work was already included.
A simple change-order clause has five parts:
A written request from the client, naming the change.
A written estimate of cost, schedule and any knock-on effects on other milestones.
Approval by a named person on each side.
An amended SOW exhibit, so the record stays current.
A rule that unapproved work is not billable and not required.
Pair this with an agile working rhythm and the process stays light. Our guide to agile app development explains how sprint reviews and the change process fit together.
Warranty, liability and termination
Warranty. Define when coverage starts, which defects qualify and how quickly the developer will respond. For example, one agile contract template uses a 60-day period after final delivery for material defects. State whether correction of covered defects is included in the project fee.
Liability. Review and negotiate the cap, any exceptions to it and any exclusions for categories of damages. Discuss how the agreement treats confidentiality breaches, IP infringement and indemnity obligations. Consider whether the proposed terms fit the size of the project and the risks associated with what the app handles, such as payments or personal data.
Termination. Look for these elements:
Termination for uncured material breach, with a notice and cure period.
Termination for convenience, and how work completed to date is paid.
Handover duties, including when the developer delivers source code, design files and documentation, and transfers account ownership or grants administrator access through each platform’s supported process.
Survival of confidentiality and IP clauses.
Open source. Ask for a disclosure of open-source components and their licenses. Some licenses place conditions on how your own code can be distributed, and you want to know that before an investor's diligence does.
Because liability, IP and indemnity language can carry real consequences, have a licensed attorney in your state review the final agreement before you sign.
Post-launch maintenance and support
Spell out what the project fee covers after launch. Legal 500 discusses defining post-delivery support and offering separate packages for work beyond the agreement’s scope.
In practice, define the following.
Defect coverage. State when the warranty starts, how long it lasts and which defects the developer will fix under the project fee.
New requests. Define how the team evaluates and approves changes to the agreed functionality.
Ongoing support. Set the scope, pricing and response times for work such as OS updates, dependency upgrades and monitoring.
Optional retainer. Describe what an ongoing support package includes and how additional work is approved.
Our perspective
Most contract trouble we see between founders and agencies is not about law. It is about communication that the contract failed to structure. When the people writing the SOW are not the people building the product, requirements get lost in translation, and the acceptance criteria turn into guesses.
That is why we work the other way. Senior developers and designers speak with you directly from kickoff to launch, so the scope you sign is the scope the builders understand. Questions get answered in hours, not passed down a chain, and that shortens decision latency on both sides.
Our advice is to treat the agreement as a communication tool first. Name the decision-makers. Write testable acceptance criteria. Put the change process in writing. Then insist on the assignment language that makes the code yours. A partner confident in its work will welcome all four.
Finally, plan for life after launch while you are still drafting. Apps keep evolving, and having support terms in place from day one means the team that built your MVP can keep improving it.
What to review before using any template
Templates are a starting point. Before you adapt one, run through this checklist:
Governing law and venue: does it match your state and your agency's?
SOW attached: a template without a specific exhibit is a shell.
Order of precedence: which document wins if the SOW and the agreement conflict?
IP language: present assignment, background IP license, subcontractor assignments.
Acceptance mechanics: review window, cure period, deemed acceptance, named reviewer.
Payment triggers: tied to deliverables, with a reasonable deposit.
Account ownership and access: identify who controls the repository, cloud hosting, app stores and analytics accounts at handover, and how ownership or administrator access is granted.
Security and data duties: especially if you will store user data.
Warranty and support length: stated in days with a defect definition.

FAQ
Can I just download a free software development agreement template?
Yes, a template is a reasonable starting point, but it needs a project-specific SOW, the right governing law and IP language that matches your goals. Have an attorney licensed in your state review the adapted version before you sign.
Do I own the app code automatically if I pay for it?
Under U.S. law, copyright generally starts with the author. Payment alone leaves ownership with the existing rights holder. To acquire copyright in the agreed deliverables, specify the rights being assigned and when the transfer takes effect in a signed writing.
Should an MVP contract be fixed-price or time-and-materials?
Fixed-price suits a well-defined SOW and gives budget certainty, while time-and-materials suits work where requirements will evolve. Whichever you choose, add a written change-order process so scope changes are priced and approved before work begins.
How should I tie payments to progress?
For fixed-price work, specify the signing payment, the acceptance criteria for each billed milestone and when each invoice is payable. For time-and-materials work, specify the rates, how hours are recorded and approved, and the billing schedule.
What support should the agreement include after launch?
Specify when defect coverage starts, how long it lasts, which defects qualify and how quickly the developer will respond. Set separate terms for ongoing maintenance such as OS updates, monitoring and new features.
