Pursenal is a free and open-source personal and business finance manager built with Flutter, designed to help users track income, expenses, and budgets across multiple profiles and currencies. Unlike simple expense trackers, Pursenal implements a robust double-entry accounting system to ensure financial accuracy while supporting offline use. It targets individuals and small business owners who need a unified, cross-platform solution to manage their finances without relying on cloud-dependent apps. With support for Android, Windows, and Linux, Pursenal offers a local-first approach to financial data privacy and accessibility.
Built using Flutter and Drift, Pursenal leverages the power of Dart to deliver a responsive UI across platforms while maintaining efficient local data persistence. The app is ideal for users who value transparency, control over their financial data, and the ability to operate without internet connectivity. Its open-source nature under GPL v3 encourages community contributions and ensures long-term sustainability.
What You Get
- Multi-Platform Support - Pursenal runs natively on Android, Windows, and Linux using Flutter, allowing seamless access to your financial data across devices without requiring cloud synchronization.
- Multi-Profile Support - Users can create and switch between separate profiles for personal and business finances, keeping transactions and budgets isolated and organized.
- Multi-Currency Support - Track income and expenses in multiple currencies, enabling global users to manage finances across borders with accurate conversions.
- Double-Entry Accounting System - Record transactions with debits and credits for accurate financial tracking, suitable for users familiar with basic accounting principles.
- Budget Management - Create custom budgets and monitor spending against them using visual charts that update in real time.
- Visual Analytics - Generate detailed charts and reports to analyze spending patterns, income sources, and budget adherence over time.
- Notifications & Reminders - Set daily alerts to remind users of upcoming bills, budget limits, or financial tasks to maintain consistency.
- Project-Based Tracking - Assign income and expenses to specific projects for granular financial analysis, useful for freelancers or small business owners managing multiple clients.
Common Use Cases
- Building a personal finance dashboard for offline use - A user without reliable internet access tracks daily expenses and income on their Linux laptop, using Pursenal’s local storage to maintain accurate records without cloud dependency.
- Managing small business finances across currencies - A freelance designer based in Germany invoices clients in USD and EUR; they use Pursenal to log payments, categorize them by client project, and monitor profit margins in real time.
- Problem → Solution flow: Overwhelming expense tracking → Centralized, categorized reporting - A user struggles with scattered bank statements and cash receipts; they use Pursenal to log every transaction with categories and tags, then generate monthly reports to identify overspending.
- Team/workflow scenario: Freelancers managing multiple clients - A solo consultant uses separate profiles for personal and business finances, assigns project-based expenses to client invoices, and sets budget reminders to avoid overspending on tools or software subscriptions.
Under The Hood
This project is a personal finance management application built with Dart and Flutter, designed to provide a cross-platform solution for tracking and organizing financial data. It adopts a structured approach grounded in domain-driven design principles and emphasizes clean separation of concerns through modular architecture.
Architecture
The codebase follows a multi-layered structure that clearly separates presentation, business logic, and data access components.
- The architecture employs a layered pattern with distinct modules for core functionality, data handling, and UI elements
- Abstract repositories define contracts for data operations, enhancing testability and reducing coupling across modules
- Domain models are cleanly separated from database entities, with mapper extensions facilitating smooth data transformations
- Extension methods and dependency injection are used to manage cross-cutting concerns effectively
Tech Stack
The project leverages Dart and Flutter as its core development stack, enabling multi-platform deployment.
- Built with Dart and Flutter, supporting both mobile and web platforms from a single codebase
- Relies on drift for database operations, provider for state management, and flutter_gen for code generation
- Integrates Gradle and CocoaPods for native builds alongside standard Flutter workflows
- Testing practices are minimal, indicating a reliance on integration or manual testing over extensive unit test coverage
Code Quality
The codebase reflects moderate quality with a focus on structured development and reusable components.
- Type annotations are consistently applied, contributing to improved code clarity and maintainability
- Reusable extensions and domain-driven design patterns support clean, DRY implementation practices
- Error handling is basic in scope, with limited use of advanced exception management strategies
- The directory structure is well-organized, promoting ease of navigation and modularity
What Makes It Unique
This project distinguishes itself through thoughtful architectural choices and a focus on developer experience.
- Extensive use of Dart extensions enables clean handling of cross-cutting concerns without bloating core logic
- A robust repository pattern ensures a clear separation between domain logic and persistence concerns
- The implementation emphasizes consistency in code organization and utility extensions for enhanced developer productivity
- Domain-driven design principles are applied consistently, setting it apart from generic finance tools
