Invoice Maker is a Flutter-based mobile application designed to help freelancers, small businesses, and service providers create, manage, preview, and share professional invoices with ease.
Creating invoices manually is time-consuming and often error-prone. This app simplifies the process by providing a streamlined workflow for:
- creating invoices quickly from reusable client and item data
- previewing invoices before sending them
- generating PDF/print-friendly documents
- organizing invoices and business details in one place
- tracking invoice-related activity from a central dashboard
- Flutter
- Dart
- GetX for state management and navigation
- BLoC Cubits for UI-related state handling
- GetStorage and SharedPreferences for local persistence
- PDF and Printing packages for document generation
- Intl for date and formatting utilities
The app follows a simple user flow:
- Splash screen initializes the app and checks the current session.
- Users log in or continue from a saved session.
- The dashboard provides an overview of recent invoices and quick actions.
- Users can manage clients, items, and invoices from the main navigation.
- A new invoice can be created, previewed, and exported as a PDF or printed.
- Settings, profile, analytics, and templates are available from the more menu.
