India's First & Only AI-Native GST Audit Platform
Stop Losing Crores to GST Compliance Gaps
PersivAI Assist runs 7 deep-audit modules across your entire purchase register in minutes - not weeks. Recover blocked ITC, catch RCM leakage, fix HSN mismatches, and reconcile GSTR-2B - all powered by deterministic rules and AI judgment working together.
The problem
Indian Businesses Bleed ₹2.5 Lakh Crore Annually in GST Leakage
Blocked ITC Goes Unnoticed
Section 17(5) has 8+ categories of ineligible credit. Manual teams routinely miss blocked items buried in thousands of line items.
RCM Liability Missed
Reverse Charge under S.9(3) and S.9(4) is complex. Unregistered vendors, notified services, imports - each has different rules that slip through.
GSTR-2B Mismatches Pile Up
Supplier non-filing, amount differences, component mismatches - reconciling line-by-line against 2B is a nightmare at scale.
Wrong Tax Type Applied
CGST/SGST charged on inter-state supplies (or IGST on intra-state) creates demand notices, interest, and penalties during assessments.
Why PersivAI
Not Just Another Compliance Tool.
An AI Audit Partner.
Deterministic Rules + AI Judgment
Hard rules catch the obvious. AI catches the nuanced - ambiguous descriptions, edge-case HSN codes, borderline RCM scenarios. Two layers, zero gaps.
3-Tier Confidence Scoring
Every row gets a 0-100 confidence score. FLAGGED (high confidence issue), REVIEW (needs human eye), CLEAN (verified OK). Your auditors focus only where it matters.
AI Verification Layer
Flagged rows go through a second adversarial AI pass to catch false positives. Reduces noise significantly before your team even sees results.
Pluggable Engine Architecture
Adding a new audit type requires zero frontend changes. Write the engine, register it, configure in DB - the UI adapts automatically. Future-proof by design.
Penalty Exposure Calculator
Instant estimates of tax liability + interest + penalty for every flagged row. Know your exposure before the department does.
Complete Audit Trail
Immutable timeline per row - AI decisions, auditor verdicts, remarks, timestamps. Fully defensible in assessment proceedings.
Audit modules
7 Deep-Audit Engines. One Platform.
Each module is purpose-built for a specific GST compliance area. Run them individually or all together on a single upload.
Ineligible ITC
8 deterministic rules identify blocked credit - motor vehicles, food, health, works contract, composition vendors, time-barred invoices. AI triage handles ambiguity.
RCM Validation
Archetype-routed rules + bidirectional AI semantic classification. Catches missed RCM on notified services, unregistered vendors, and imports.
ITC vs GSTR-2B
6-tier matcher with autonomy bands. Flags missed-in-books, NOT_IN_2B (supplier non-filing), amount mismatches, ISD credits, and blocked credits.
GSTR-1 vs Books vs E-Invoice
IRN/STRICT/LOOSE/PAN cascade matching across books, GSTR-1 mirror, and IRN log. Adversarial verifier with hard-block guards.
HSN/SAC Audit
AI maps descriptions to correct HSN codes, validates rates against historical rate schedules. Catches rate mismatches and wrong classifications.
Tax Type Audit
Detects CGST/SGST vs IGST misapplication using AI-generated branch-state mappings. Prevents demand notices from wrong tax type.
GST Compliance Agent
Autonomous deep-dive audit using DuckDB + multi-iteration OpenAI reasoning loops. Covers 8 GST audit points with auto-generated PDF/Excel reports. The future of audit - today.
How it works
From Excel Upload to Audit Report in 3 Steps
Upload Your Data
Drop your purchase register Excel file. Our AI auto-discovers schema - no rigid templates, no column mapping needed.
AI Runs the Audit
Deterministic rules fire first. Then AI handles edge cases, verifies flags, scores confidence, and calculates penalty exposure. Real-time logs stream progress.
Review & Act
Virtualized table shows all rows with color-coded status. Filter by error type, bulk-review, export to Excel. Your auditors handle only what AI couldn't resolve.
