Why GSTAgent is Different

Not matched or unmatched.
Nine levels of certainty.

Every other GST reconciliation tool gives you two outcomes. GSTAgent gives you nine — each with a confidence score and a plain-English action. Plus two separate portals for two completely different users.

🎯

9-Status AI Engine

MATCHED, SOFT_MATCH, INV_CONFLICT, MISSBOOKS, UNREPORTED, TIMING_PENDING, SERIES_ANOMALY, DUPLICATE_PR, BLOCKED_2B. Each with an exact action.

Only tool in India
🔐

Invoice Data Never Leaves

All file processing happens in your browser. Your GSTR-2B and Purchase Register are never uploaded to any server. Privacy by architecture, not policy.

Privacy-first

AI Confidence Scoring

Every matched invoice gets a 0–100% confidence score. Fuzzy matching normalises INV/001, INV001, and 001 as the same. 15+ format variants handled.

Levenshtein + AI
📊

Two Portals, One Engine

CA firms get multi-client management. Business owners get a direct single-GSTIN portal. Completely different interfaces — same powerful engine underneath.

CA + Direct B2C
📈

Supplier Health Tracking

After 3 months of data, GSTAgent shows which suppliers are chronically non-compliant, their filing rate, and cumulative ITC at risk month-over-month.

Multi-month patterns
🤖

AI Agent Roadmap

Q3 2026: Predictive ITC risk alerts. Q4: Auto supplier follow-up. 2027: Autonomous agent that reconciles without any file upload. A platform, not a tool.

Platform vision
The Reconciliation Engine

Every invoice classified.
Every rupee accounted.

The engine processes GSTR-2B and Purchase Register together, normalises 15+ invoice number formats, and assigns one of nine statuses — each with the exact action needed.

MATCHED
Perfect match — claim ITC confidently
SOFT_MATCH
Invoice variant matched — verify amount
INV_CONFLICT
Invoice found but amounts differ
📥
MISSBOOKS
In 2B not in books — recoverable ITC
UNREPORTED
In books, supplier not filed — blocked
TIMING_PENDING
Prior month invoice — await next 2B
📋
SERIES_ANOMALY
Invoice breaks supplier numbering series
DUPLICATE_PR
Same invoice booked twice in books
🔒
BLOCKED_2B
2B flags ITC unavailable — do not claim
MISSBOOKS alone — invoices in 2B not yet booked in Tally — accounts for 2–5% unrecognised ITC. GSTAgent surfaces every one automatically.

GST Audit Engine

Every CA does reconciliation.
Nobody does GST audit.

Rule 37, Rule 42/43, GSTR-9, Supplier Risk — in one engine. No other platform in India offers all four. The tool that protects your client from a Section 73/74 notice before it happens.

Full Story →CA Portal →Business Portal →
01
Rule 37 — 180 Day ITC Tracker
Section 16(2) CGST Act

Upload Purchase Register. Every invoice tracked against the 180-day payment deadline. Auto-flags overdue invoices, computes DRC-03 interest at 18% p.a., generates GSTR-3B Table 4(B)(2) entries.

Missing this = interest liability + ITC reversal
02
Rule 42/43 — ITC Reversal Calculator
Rules 42 & 43 CGST Rules

Enter monthly turnover and ITC. Computes D1 reversal for exempt supplies (Rule 42) and capital goods reversal over 60 months (Rule 43). Annual reconciliation figure for September return.

Miscalculation = wrong GSTR-3B filing + scrutiny
03
GSTR-9 Annual Working Sheet
Annual Return GSTR-9

Enter all 12 months of GSTR-3B data. Auto-populates GSTR-9 tables, cross-checks ITC claimed vs 2B, detects discrepancies, and flags Section 73/74 notice risk before you file.

Undetected discrepancy = demand + ₹10,000 min penalty
04
Supplier Risk Score
Section 16(2)(aa) compliance

Upload reconciliation export. Scores every supplier by filing rate, consecutive missed months, and ITC at risk. Generates priority follow-up queue with WhatsApp templates.

High-risk suppliers = ITC permanently lost

Privacy Architecture

Your invoices never
leave your device.

We made an architectural decision no other Indian GST software has made: all file processing runs in your browser. Your GSTR-2B and Purchase Register are processed locally — the engine runs on your machine, not our servers.

What we store: reconciliation results and ITC summaries only — never your raw invoice data. We cannot be compelled to produce your invoice details because we do not have them.
