AI-POWERED CA AGENT FOR SMALL BUSINESSES

Abstract

The CA Agent is a full-stack, cloud-native web application designed to democratise professional accounting and taxation services for small businesses, freelancers, and sole proprietors in India. The system integrates a React/Typescript single-page application with a Supabase-managed PostgreSQL backend and an n8n-orchestrated multi-agent AI pipeline powered by Google Gemini 2.5 Flash, delivering expert-grade financial consultation through a conversational chat interface. The platform addresses three critical pain points: inaccessible and expensive CA consultations, time-consuming manual invoice processing, and the complexity of navigating Indian taxation regulations. Users can submit natural language accounting queries, upload invoice documents in image or PDF format for automated field extraction, and receive regulation-grounded taxation advice through a RetrievalAugmented Generation pipeline built over digitised Indian tax law documents stored in a Pinecone vector database. The system achieves sub-4-second end-to-end latency for text queries, 93% factually accurate taxation responses, and up to 96% invoice field extraction accuracy on structured documents. All user data is secured through Row Level Security policies enforced at the PostgreSQL layer. The CA Agent represents a scalable, cost-effective alternative to traditional accounting consultations for routine financial queries and bookkeeping tasks.
