Stop losing money on
App Developer projects.
Without a clear maintenance boundary, a 'quick bug fix' inevitably evolves into an unpaid weekend of feature building. If you don't define where support ends and development begins, you are essentially providing a lifetime warranty for a one-time fee.
Pro Tip
Include a 'Change Request' clause that stipulates any request requiring more than two hours of logic restructuring automatically converts from a 'maintenance task' to a 'paid project' under a separate Statement of Work.
API and OS Rot
Mobile OS updates can deprecate code overnight. Without this agreement, you may be forced to rewrite core logic for free just to keep the app on the App Store.
Scope Creep via Support
Clients often mask new feature requests as 'bugs.' Without defined exclusions, you lose the leverage to charge for new development work.
Liability for Downtime
If a server fails and there is no agreement defining your responsibilities and response times, you could be held liable for the client's lost revenue.

What is a App Developer Maintenance Agreement?
An App Developer Maintenance Agreement is a legal contract that defines the ongoing technical support, security updates, and bug fixes provided after an app's launch. It distinguishes routine upkeep from new feature development, ensuring developers are paid for continuous monitoring and compatibility updates.
Quick Summary
This page provides a comprehensive framework for app developers to transition from project-based work to recurring maintenance. It emphasizes the legal necessity of separating 'maintenance' (keeping the app functional) from 'new development' (adding features). By utilizing this template, developers can protect their time, secure recurring revenue, and set clear Service Level Agreements (SLAs) that prevent client disputes over OS updates, API changes, and emergency support requests.
Why App Developers need a clear maintenance agreement
For app developers, software is never truly 'finished'—it is merely 'released.' Mobile ecosystems are volatile; iOS and Android update their requirements annually, APIs evolve, and security vulnerabilities emerge daily. An App Developer Maintenance Agreement is the only thing standing between a profitable recurring revenue stream and 'death by a thousand updates.' This document legally distinguishes between 'keeping the lights on' (OS compatibility, security patches, and server monitoring) and 'building a new room' (new features or UI overhauls). Without it, clients often expect free labor for any issue that arises post-launch, regardless of whether the cause was a bug or a third-party platform change. Formalizing this relationship protects your hourly rate, sets realistic client expectations regarding response times, and ensures you are compensated for the constant vigilance required to keep a modern application functional in a changing digital environment.
Do you need an invoice or a contract?
Invoices help you get paid, but they do not define scope, revisions, or ownership. For most projects, professionals use both a contract and an invoice to protect their work and cash flow. MicroFreelanceHub bundles both into a single link.
Real-world scenario
Developer Marcus finished a food delivery app for a client. Three months later, Google Maps updated its API, breaking the app's tracking feature. Simultaneously, the client asked to add a 'loyalty points' system, claiming it was just 'minor maintenance.' Because Marcus had a solid Maintenance Agreement, he could clearly show that the API fix was covered under the monthly retainer (Maintenance), but the loyalty system was an 'Excluded Service' requiring a new $3,000 quote. The client, seeing the clear distinction in the signed contract, paid the invoice without argument. Marcus saved 40 hours of unpaid labor and maintained a professional relationship because the boundaries were established before the conflict arose.
🛡️ What this maintenance agreement covers:
- ✓Security patch installation and dependency updates
- ✓Operating System (iOS/Android) compatibility checks
- ✓Minor bug fixes (defined as corrections to existing logic)
- ✓Database optimization and regular cloud backups
- ✓Server uptime monitoring and hosting management
- ✓Monthly performance and health reporting
Pricing & Payment Strategy
Standard app maintenance is typically priced as a monthly retainer, usually 15-20% of the initial development cost per year. This can be structured as a flat monthly fee for 'up to X hours' of support, with an overage rate for additional time. For high-stakes apps, developers may charge a premium for 24/7 monitoring or guaranteed 4-hour response times (SLAs).
Best practices for App Developers
Define 'Bug' vs 'Feature'
Explicitly define a bug as 'code not performing as originally specified' and a feature as 'new functionality.'
Establish Tiered SLAs
Set different response times for 'Critical' (app down) vs 'Minor' (UI glitch) issues to manage client expectations.
1. Included Maintenance Tasks
The Developer shall provide the following ongoing support services to ensure the Application remains functional and secure: (a) Monitoring of server uptime and performance; (b) Installation of security patches and critical updates to third-party libraries; (c) Testing and minor code adjustments to ensure compatibility with new versions of iOS and Android; and (d) Correction of documented bugs where the software fails to perform according to original specifications.
2. Excluded Services (New Paid Work)
Services not specifically listed in Section 1 are considered 'New Work' and are subject to separate billing. Excluded services include, but are not limited to: (a) Creation of new features or significant changes to existing functionality; (b) Graphic design and UI/UX overhauls; (c) Integration with new third-party APIs; and (d) Data entry or content management services. Any work requested in these categories will require a separate Statement of Work (SOW).
3. Response Times & Service Levels (SLA)
The Developer will respond to support requests based on the following severity levels:
- Critical (App Down): Initial response within 4 hours; status updates every 2 hours.
- Major (Core Feature Broken): Initial response within 12 hours.
- Minor (Cosmetic/Non-Essential): Initial response within 3 business days.
4. Payment for Ongoing Support
The Client shall pay a recurring monthly fee (the 'Retainer') as specified in the pricing schedule. This retainer covers up to [X] hours of maintenance per month. Hours are not carried over to subsequent months. Any maintenance work exceeding the allotted hours will be billed at the Developer's standard hourly rate of $[Amount], provided the Client gives written approval for the overage.
5. Cancellation Policy
Either party may terminate this Maintenance Agreement by providing at least thirty (30) days' written notice to the other party. In the event of termination, the Client shall pay for all services rendered up to the effective date of termination. Upon final payment, the Developer will provide the Client with all necessary credentials and documentation required to transition maintenance to a new provider.

Frequently Asked Questions
What happens if a new iOS update breaks the app?
Under this agreement, updating code for OS compatibility is considered 'Standard Maintenance,' provided it falls within the allotted monthly hours. Total rewrites due to major OS shifts may trigger additional fees.
Can I cancel a maintenance agreement if a client becomes difficult?
Yes, our template includes a 'Termination for Convenience' clause, allowing either party to end the agreement with 30 days' notice.
