FinTrack aims to help young professionals in India understand spending, set goals, and build better money habits without spreadsheet complexity. The MVP must validate retention through fast onboarding, reliable expense capture, and clear monthly insights.

Stacklane Labs proposes an eight week delivery program using React Native, Node.js, and PostgreSQL with milestone based billing and a dedicated product trio: engineering lead, mobile developer, and QA.

This document defines feature scope, sprint plan, commercial terms, success criteria, and assumptions required to ship to both app stores with a maintainable codebase your team can extend in Phase 2.

Our understanding of your current challenges, based on discovery calls and shared data:

• Users abandon finance apps when onboarding exceeds three minutes or bank linking fails on mid tier Android devices.
• Competing products overwhelm first time users with features before core habit loops are established.
• Founders need store ready builds with privacy compliant data handling aligned to Indian regulations.
• Without a documented API and admin tooling, support teams cannot resolve user issues efficiently at launch.

We recommend the following approach to address these challenges and deliver measurable outcomes within the timeline below.

• Deliver a focused MVP covering auth, expense entry, budgets, insights, exports, and account management with DPDP conscious defaults.
• Execute in four two week sprints with demoable increments, shared backlog in Linear, and weekly stakeholder reviews.
• Host infrastructure on managed cloud with staging and production environments, monitoring, and crash reporting from day one.
• Provide technical documentation, API specification, and knowledge transfer so internal hires can continue development post handoff.

• Production ready mobile apps submitted to App Store and Google Play
• Node.js API with OpenAPI documentation and environment configuration guides
• PostgreSQL schema migrations and seed scripts for staging
• Basic admin dashboard for user lookup and support actions
• CI/CD pipeline with build, test, and deploy to staging
• Security checklist covering auth, storage encryption, and data deletion flows

Exclusive of GST. Each sprint invoiced at start. Payment due Net 7 via NEFT or Razorpay.

• 12 shipped consumer apps in fintech and health with average 4.8 store rating
• India first QA matrix including popular Xiaomi, Samsung, and OnePlus devices
• Fixed sprint scope with transparent change request process and weekly burn down reports

“Stacklane hit every sprint demo on time. Our MVP reached five thousand installs in the first month without critical incidents.”

• •Client provides Figma designs, copy, and store accounts by Sprint 1 day three or timeline shifts accordingly.
• •One dedicated product owner available for daily async questions and sprint review attendance.
• •Scope changes triaged to backlog. Change requests billed at ₹3,800 per engineering hour with written estimate.
• •Source code delivered to client GitHub organization. Thirty day warranty for defects in delivered scope only.
• •Out of scope for MVP: bank aggregation, UPI auto import, multi currency, and web client. Quoted separately for Phase 2.
