The dilemma it solves

GST compliance is a tax on every Indian business.

Manual invoice handling. Manual data entry into Tally and Zoho. Manual GSTR-2B reconciliation. Vendor follow-ups for missing invoices. Audit trail panic. The cost is paid in finance team hours that should be spent advising the business, not chasing mismatches.

40+ hrs/mo

spent by an average mid-market tax team on manual reconciliation. Compressed to hours with the co-pilot.

₹13–17 L/yr

spent on GST compliance overhead per business. Most of it is rework that disappears when reconciliation is governed.

162 tests

in the AI service. 88% coverage. Engineering rigor designed for an audit, not a demo.

How it works

Four agents, one supervisor, one filing.

An orchestrator agent reads intent, routes work, and escalates to a human reviewer above a configurable threshold. Four domain agents do the work. Every action is logged, every output is traced, every override is recorded.

AGENT 01

Ingestion

Pulls invoices from email, drives, and ERP exports. SHA-256 deduplication, file-type validation, vendor hint extraction.

AGENT 02

Extraction

Vision-language models extract line items, GSTIN, HSN, taxable values, and tax splits from PDFs and scans. Outputs a structured invoice record with confidence scores.

AGENT 03

Reconciliation

Match engine compares purchase register lines against GSTR-2B. Probabilistic matching, fuzzy GSTIN handling, period-shift tolerance, ITC eligibility checks.

AGENT 04

Resolution

Drafts vendor follow-ups, generates exception summaries, escalates above the human-review threshold. Hands the CFO a filing-ready summary at month end.

Who uses it

Three roles, three reasons it matters.

CFOs · Heads of Finance

Stop month-end being a fire drill. Get a filing-ready summary with exceptions named, reasons surfaced, and human review only where it matters.

CA firms and AP teams

Triple your throughput per analyst. Spend the saved hours on advisory work, not on chasing GSTR-2B mismatches.

CIOs · CTOs

A reference architecture for governed agentic AI in production. Adapt the same pattern to AP, vendor risk, audit readiness.

Why it matters as proof

What governed agentic AI looks like in production.

GST Co-Pilot is not a prototype. It is the same pattern we use for every governed agentic engagement, applied to a domain we know cold. Everything ClarityAI scores, GQData feeds, and GQ Agents runs is visible here, end to end, on a real workload that already moves money.

Other live verticals

Same pattern, different domain.

GST Co-Pilot is one of several vertical accelerators we ship. Each one applies governed agentic AI to a specific industry.

Get this month's GST done without the all-nighters.

We'll walk you through a real reconciliation cycle on your own data, in a controlled environment. You see exactly where the hours go.
