VECA (Virtual Executive for Chartered Accountants) is a full-stack, AI-powered practice management platform built specifically for CA firms and finance professionals. It automates the end-to-end workflow of a CA office — from client onboarding and compliance tracking to automated document collection, HR management, and AI-assisted data extraction — all within a single, secure, web application.

The platform is built on Django 5 (backend) and React 18 (frontend), secured by JWT authentication with OTP-based registration, and powered by Anthropic Claude and Google Gemini AI APIs for intelligent document processing and task automation.

CA firms juggle hundreds of compliance deadlines, client documents, staff assignments, and government portal credentials simultaneously. The traditional approach relies on spreadsheets, WhatsApp reminders, and manual follow-ups — leading to missed deadlines, lost documents, and unproductive staff hours. VECA replaces all of this with a unified automated platform.

1. Dashboard: Real-time stat cards (total clients, pending tasks, overdue count, today's due), upcoming task table, analytics, and system health monitoring.
2. Client Management: Full CRUD with bulk Excel import, work-type assignment per client, client portal token generation for self-upload, and client-level document tracking.
3. Work Types (Task Categories): Configurable compliance categories (e.g., ITR, GST, TDS) with period options, reminder schedules, subtask structures, AI extraction prompts, and auto-driven pipeline configuration.
4. Task Management: Task creation, assignment, due-date tracking, subtask completion, document attachments, built-in timer (start/pause), task transfer between staff, and completion workflow with document upload.
5. Auto-Driven Workflow: Fully automated email reminder pipeline: sends reminders to clients, monitors Gmail for replies, uses AI (Claude/Gemini) to extract data from attached documents, generates Excel output, and escalates on non-response.
6. Document Vault (DMS): Organised document management system with ICAI file-type classification, engagement category groupings, upload, download, and compliance document tracking.
7. Credential Vault: Encrypted storage of client portal credentials (income tax, GST, MCA, etc.) with reveal-on-demand access control, per-portal-type organisation, and client-linked lookup.
8. HR Module: Employee profiles, holiday calendar, leave types and balances, leave request → approval → appeal workflow, attendance dashboard, and payroll management.
9. Google Sync Hub: Multi-account Google integration: sync tasks to Google Tasks, compliance deadlines to Google Calendar, client documents to Google Drive, and Gmail monitoring for incoming client replies.
10. Reports: Configurable report templates with PDF generation (via ReportLab + Matplotlib), ad-hoc PDF download, scheduled email delivery, and report preview.
11. Email System: Email template library, multi-sender account management, full email log (sent/failed/pending), delivery analytics, and test-send capability.
12. Compliance Tracker & PMLA: Compliance status tracking across clients, PMLA (Prevention of Money Laundering Act) module for CA firms, and checklists for engagement management.
13. Audit Trail: Immutable log of all significant actions within the platform for accountability and regulatory compliance.
14. Notifications & Alerts: Real-time in-app notification centre, smart alert configuration, webhook delivery for external integrations, and WhatsApp/Telegram bot notifications.

The Auto-Driven Workflow is VECA's most distinctive capability. It turns every compliance task into a fully automated pipeline that runs without staff intervention:

1. End-to-end automation: VECA is not just a task tracker — it actively chases clients, reads their documents with AI, and generates outputs without human intervention.
2. CA-specific design: Work types, reminder cadences, TDS extraction prompts, GSTR1 processing, PMLA module, and client portal upload links are all purpose-built for CA practice.
3. Multi-LLM flexibility: The AI provider is configurable — switch between Anthropic Claude and Google Gemini without code changes.
4. Unified platform: Client management, compliance, HR, documents, credentials, Google sync, reports, and messaging — all in one login.
5. Granular permissions: Staff access can be restricted to specific modules and actions (e.g., can upload documents but not delete clients).
6. Real-time monitoring: The Auto-Driven Monitoring dashboard shows every task's pipeline stage, last action, and allows instant intervention.
7. Client self-service: Client Portal upload links allow clients to submit documents directly without needing a login or account.
8. Audit-ready: Every action is logged; email delivery is tracked; extraction history is preserved — giving a complete paper trail for any compliance query.

Document Data Extraction

When a client emails a TDS certificate, Form 26AS, GST document, or bank statement, Claude/Gemini reads the attachment and extracts structured fields (deductor name, PAN, amount, period, etc.) based on a configurable extraction prompt.

TDS-Specific Extraction

Pre-built extraction prompts for TDS Form 16, Form 16A, and Form 26AS are included, with support for multi-deductor extraction and discrepancy detection between expected and extracted values.

Excel Auto-Population

Extracted data is mapped to columns in a pre-uploaded Excel template, producing a ready-to-use working file automatically.

Configurable Prompts

Each Work Type can have a custom AI extraction prompt, making the system adaptable to any document type a CA firm receives.

AI Usage Tracking

The platform tracks AI API usage (tokens consumed, cost estimate, success/failure rate) per task and organisation, visible in the AI Usage dashboard.

VECA implements Anthropic Claude's Tool Use API following the Model Context Protocol (MCP) pattern. The backend defines 21 structured tools that expose VECA's full data layer to Claude (and other LLMs). This allows the AI to read from and write to VECA — tasks, clients, attendance, leave, payroll, documents — through natural language conversations on Telegram.

The tool definitions are explicitly designed as MCP-compatible: each tool has a name, description, and typed parameter schema — the same structure an MCP server exposes to Claude. The LLMService class converts these definitions into the provider-specific format for Anthropic (input_schema), OpenAI/Groq (function calling), and Google Gemini (functionDeclarations) — making the bot provider-agnostic.

How the Bot Conversation Works

The AI assistant system prompt instructs Claude to act as "VACA AI Assistant" — a CA practice management assistant that is concise, uses bullet points, formats amounts in Indian Rupees, and clarifies ambiguous requests before taking action.

VECA delivers measurable operational improvements for CA practices:

1. Zero missed deadlines: Automated task generation and escalating reminders ensure no compliance due date is overlooked.
2. Reduced manual follow-up: The auto-driven pipeline eliminates the need for staff to manually chase clients for documents.
3. Faster data entry: AI extracts and populates data from client-submitted documents directly into Excel, replacing hours of manual typing.
4. One login, everything: Staff no longer switch between spreadsheets, email, WhatsApp, and multiple tools — everything is in VECA.
5. Transparent accountability: Every task has an owner, a timer, a due date, and an audit log — managers can see exactly what is happening.
6. Client self-service: Clients submit documents via a secure portal link — no accounts, no app installs required for them.
7. Compliance confidence: Compliance Tracker, PMLA module, Audit Trail, and Checklists give firms the documentation needed for peer reviews and regulatory queries.
8. Scalable practice: Multi-tenant architecture means one deployment serves multiple firm sizes; the platform scales with the practice.
