  1. GST Analysis

Analysis Via Credentials

GST Analysis (Credentials) retrieves and analyses a borrower's GST return data using their GST portal login credentials, giving you structured insights into their business health and compliance without any manual portal work.
It evaluates:
Filing behaviour - GSTR filing patterns, timeliness, compliance-health scoring, active/inactive status
Sales & purchase analysis - B2B/B2C/export breakdowns, Input Tax Credit (ITC) trends, customer and supplier concentration
Reconciliation & risk - GSTR-1 vs. GSTR-3B variance detection, Reverse Charge Mechanism (RCM) flags, state-wise transaction mapping
Workflow: Generate Session (with username, Base16 - encoded password, and consent) → Start Analysis → Check Status → Retrieve Report
Use this flow when you already hold the customer's GST portal credentials and consent, and want a direct, single-step authentication into their GST data.
