Stop losing money on Mobile App Designer projects.
Send your first 3 milestone approval agreements for free. Designing app screens without signed milestones means a client can demand an entire UI overhaul right before handoff, claiming they 'never approved' the initial user flows. Without a locked-in milestone approval, you risk losing weeks of Figma design hours to infinite, unpaid revision loops.
No credit card required. Setup takes 30 seconds.
Build the agreement, add your deposit amount, and send one secure client link for signature and payment.

Mobile App Design Milestone Approval Agreement
This Milestone Approval Agreement ("Agreement") formalizes the review, acceptance, and payment release for the specific mobile app design deliverables detailed below.
1. Deliverable Review & Phase Identification
The Designer has submitted the following specific deliverables for formal client review:
- Project Phase: [e.g., Phase 2: High-Fidelity iOS/Android UI Screens]
- Figma Review Link: [Insert View-Only Figma Link]
- Interactive Prototype Link: [Insert Interactive Prototype Link]
- Scope of Deliverables: [e.g., 12 Core Screens, including Onboarding, User Profile, Checkout Flow, and UI Kit/Design System Components]
2. Acceptance Criteria
By signing this document, the Client acknowledges that the deliverables meet the following technical and aesthetic criteria:
- The user flows align with the wireframes approved in the previous milestone.
- UI components conform to standard mobile design guidelines (iOS Human Interface Guidelines / Android Material Design).
- Typography, color palettes, and component states (default, active, disabled) are fully represented in the design system.
- Interactive prototype accurately demonstrates transition behaviors and user journeys.
3. Revision Limits & Feedback Scope
To keep the project on schedule, feedback and revisions are governed by the following rules:
- The Client is entitled to a maximum of [Number, e.g., 2] rounds of consolidated feedback based on this submission.
- All feedback must be submitted via Figma comments or a unified feedback document. Scattershot feedback via Slack, text, or email will not be processed.
- Revisions must align with the agreed-upon scope. Design changes that contradict previously approved wireframes or user flows are considered out-of-scope.
4. Approval & Feedback Deadline
The Client has [Number, e.g., 5] business days from the date of submission to either sign this milestone approval or submit their consolidated revision request. If no feedback or signature is received within this window, the deliverables will be deemed automatically approved, the milestone payment will be triggered, and the Designer may pause further work until communication resumes.
5. Milestone Payment Authorization
Upon digital signature of this document:
- The milestone payment of $[Amount] is immediately due and authorized for billing.
- The client authorizes the release of funds via the MicroFreelanceHub secure payment link.
- Designer-ready asset exports (SVGs, PNGs, Lottie JSONs) and Figma developer handoff files will be unlocked and shared only after this payment has cleared.
6. Post-Approval Changes (Change Orders)
Once signed, this milestone is locked. Any subsequent requests to modify, redesign, or restructure the layouts, user flows, or components approved in this phase will be subject to a formal Change Order. Post-approval design changes will be billed at the Designer's hourly rate of $[Amount]/hour or as a flat-fee addendum, requiring a separate deposit before work begins.
Infinite Revision Loops
Clients treat high-fidelity UI designs as infinite drafts, constantly tweaking button placements, colors, and fonts without triggering extra fees.
Retroactive UX Redesign
A client signs off informally on wireframes, but once high-fidelity screens are built, they demand a complete change of the underlying user journey and app architecture without paying for redesign time.
Hostage Source Files
The client demands the Figma source files and asset exports for developer handoff while stalling on the final design milestone approval and payment.
What is a Mobile App Designer Milestone Approval Agreement?
A Mobile App Designer Milestone Approval Template is a formal, phase-by-phase sign-off document that secures client approval on specific UI/UX deliverables (like wireframes or interactive prototypes), locks in revision limits, and authorizes milestone payments before the designer moves to the next phase or releases Figma handoff assets.
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 Designers need a clear milestone approval agreement
For Mobile App Designers, the gap between interactive prototypes and final developer handoff is a high-risk zone. Without formal milestone sign-offs, clients frequently treat high-fidelity mockups as drafts, requesting major UX architecture changes after UI patterns have already been established. A Mobile App Designer Milestone Approval Template protects your revenue by forcing the client to formally sign off on specific design phases—such as User Flows, Wireframes, High-Fidelity UI, and Design Systems—before moving to the next. It establishes clear acceptance criteria, limits the scope of revisions to the current phase, and triggers the release of milestone payments. By documenting that a signed milestone represents final approval of that phase, you prevent backward-looking disputes, stop 'scope creep' disguised as feedback, and ensure you are paid for every design sprint before investing more hours.
Real-world scenario
Elena, a freelance UI/UX designer, was hired to design a fintech app. After completing the interactive prototype, the client verbally praised the work but immediately sent a list of "quick tweaks" that actually required restructuring the entire onboarding flow. Instead of diving into Figma and wasting 20 hours of unpaid work, Elena used her Mobile App Designer Milestone Approval Template. She sent a secure approval request detailing the finalized user flows and UI kit. The document clearly stated that changing the onboarding flow at this stage constituted a Post-Approval Change Order billed at $150/hour, while signing off would release the 40% milestone payment. Seeing the clear terms, the client realized the cost of their late request, signed the milestone approval, authorized the payment, and deferred the onboarding changes to Version 2 of the app.
🛡️ What this milestone approval agreement covers:
- ✓Phase-specific Figma link and interactive prototype demonstration record.
- ✓Comprehensive UI Kit / Design System component sign-off list.
- ✓Explicit revision cutoff clause (e.g., maximum of 2 rounds of feedback per design sprint).
- ✓Developer handoff asset checklist (SVGs, Lottie animations, font files).
- ✓Milestone payment authorization and billing release trigger.
- ✓Post-approval change order fee structure for retrofitted design updates.
Best practices for Mobile App Designers
Never design ahead
Stop work on Phase 2 (High-Fidelity UI) until the client has digitally signed off on Phase 1 (Wireframes) and paid the associated milestone invoice.
Record prototype walkthroughs
Embed a 3-minute Loom video walking through the interactive prototype alongside the approval template to eliminate 'I didn't understand how this worked' excuses later.

Frequently Asked Questions
What if the client refuses to sign the milestone but wants to see 'just one more' design version?
Do not send new mockups. Point to the Acceptance Criteria in this template and state that additional versions outside the agreed-upon revision limit require a Change Order. Make it clear that your schedule cannot accommodate subsequent design sprints until the current phase is formally closed and paid.
Should I hand over Figma editing access before the final milestone approval is signed?
Absolutely not. Keep the client on 'View Only' access in Figma during the review process. Only transfer project ownership or invite developers with edit access once the final milestone sign-off is completed and the final payment has cleared.
