Introduction: System Architecture

System Architecture Overview

🏛️ High-Level Architecture

1. Presentation Layer

  • Web Interface: Intuitive and user-friendly web application for desktop users.
  • Mobile App: Cross-platform native apps for Android and iOS to enable on-the-go access.
  • Admin Dashboard: Comprehensive dashboard with visualizations for analytics and management.

2. Application Layer

  • Authentication Service:
    • Secure login with two-factor authentication (2FA).
    • Role-based access control for users (admin, accountant, viewer).
  • Accounting Engine:
    • Handles double-entry bookkeeping and ledger management.
    • Automates journal entries, profit & loss, and balance sheet generation.
  • Tax Compliance Module:
    • GST invoicing and tax filing integration.
    • Support for TDS calculations and filing.
  • Inventory Management Module:
    • Tracks stock levels, purchase orders, and sales orders.
    • Generates low-stock alerts and inventory reports.
  • Notifications Service:
    • Automated email and SMS alerts for overdue payments, low stock, and reminders.

3. Data Layer

  • Relational Database:
    • Stores structured data such as financial transactions, user information, and inventory records.
    • Optimized for high-volume read and write operations.
  • NoSQL Database:
    • Manages unstructured data like logs, analytics, and user activity.
  • Backup & Recovery Service:
    • Daily automated backups to ensure data safety.
    • Disaster recovery mechanisms for business continuity.

4. Integration Layer

  • API Gateway:
    • Facilitates secure communication between modules and third-party services.
    • Supports RESTful APIs for integrations with banks, tax portals, and payment gateways.
  • Third-Party Services:
    • Payment Gateway for online transactions.
    • Government APIs for GST and TDS filing.
    • SMS/Email Service Providers for notifications.

5. Security Layer

  • Encryption:
    • Data encrypted at rest and in transit using industry standards like AES-256 and TLS.
  • Firewall and Threat Monitoring:
    • Protects the system against unauthorized access and cyber threats.
  • Access Control:
    • Implements least-privilege access and regular audits.

🌟 Deployment Model

  • Cloud-Based Hosting:
    • Scalable architecture deployed on AWS/Azure/GCP for flexibility and reliability.
  • Microservices Architecture:
    • Independent modules for scalability and fault tolerance.

By integrating modular components and robust security measures, this architecture ensures a scalable, secure, and user-friendly accounting solution.
