Below are polished, client-ready versions of both documents. The proposal is written to establish confidence with a new referral client while setting clear expectations. The invoice mirrors the proposal exactly to reduce ambiguity and protect both parties. # Project Proposal ## Mobile Banking App Onboarding Flow Redesign **Prepared for:** Nexova **Prepared by:** Sarah Amelia – UI/UX Designer (Indonesia) **Project Duration:** 3 Weeks ### Opening A strong onboarding experience is one of the biggest drivers of user activation and long-term retention, especially for a mobile banking product where trust and clarity matter from the very first interaction. This project is focused on reducing user drop-off by redesigning the onboarding flow into a simpler, more intuitive experience that helps more users successfully complete registration. ### Proposed Solution Rather than simply producing new interface screens, this project is designed to improve the overall onboarding experience through thoughtful UX decisions backed by clear visual design. At the end of the engagement, you'll receive a refined onboarding flow that is easier for users to complete, along with an interactive prototype that can be tested internally, demonstrated to stakeholders, or handed directly to development. The work emphasizes usability, consistency, and implementation readiness while keeping the project focused on the agreed objectives and timeline. ### Deliverables * **8 High-Fidelity UI Screens** — Complete visual designs for the agreed onboarding flow only. * **1 Interactive Prototype** — Clickable prototype demonstrating the complete user journey across the delivered screens. * **2 Rounds of Revisions Included** — Feedback applied to the agreed deliverables after presentation of the initial design. **Out of Scope** * Additional screens beyond the agreed 8 screens * UX research, user interviews, or usability testing * Design system creation or expansion * Developer implementation or front-end development * Copywriting, illustration, or custom icon creation unless otherwise agreed * Additional revision rounds beyond the included two ### Timeline **Week 1** * Project kickoff * Review existing onboarding flow * UX direction and visual exploration **Week 2** * Delivery of the first design draft * Interactive prototype preparation * First revision round **Week 3** * Final refinements * Second revision round (if required) * Delivery of final design files and prototype **Payment Milestones** * **50% (IDR 6,000,000)** due before project commencement to secure the project schedule. * **50% (IDR 6,000,000)** due upon delivery of the final approved project files. ### Investment **Fixed Project Fee:** **IDR 12,000,000** The fee includes all deliverables listed above and **two rounds of revisions**. Additional revision requests beyond the included scope will be billed at **IDR 500,000 per additional revision round**, subject to approval before work begins. ### Closing If everything looks aligned, simply reply with your confirmation and the project can begin as soon as the upfront payment is received. Any questions or adjustments to the scope can be discussed before work starts to ensure expectations are aligned from day one.
