Cross-Platform Accounting App Development

I need a full-featured business accounting application that runs seamlessly on both iOS and Android. The build can be native (Swift/SwiftUI and Kotlin/Java) or a proven cross-platform stack such as Flutter or React Native—whichever lets us ship quickly without sacrificing performance, security, or maintainability.

Core functionality must include:
• Expense tracking
• Invoice generation
• Financial reporting
• Inventory management and stock-up payment flows

Role-based access is essential. Admin, Accountant, and Employee users each require tailored dashboards, permissions, and data scopes.

I will supply branding assets and the high-level process maps; you will take them from wireframes through polished UI, hook up a secure backend (cloud-hosted SQL or NoSQL, PCI-compliant payment gateway, and REST/GraphQL APIs), and deliver thoroughly tested builds to the App Store and Google Play. Clean, well-documented source code and deployment scripts are part of the hand-off.

Acceptance criteria will be a staging release that matches the feature list above, passes unit/UI tests, and earns sign-off from our in-house accountant on financial accuracy.
