GST Calculation & Compliance Automation
Automated GST calculation engine that validates HSN/SAC codes, checks supply criteria, performs invoice-level reconciliation against government registers, and generates audit reports.
The Business Problem
Complex institutional procurement across multiple research grants, laboratory equipment imports, and interstate vendor invoices made monthly GST calculations and GSTR-2B ITC reconciliations extremely error-prone and labor-intensive.
The Engineering Solution
Implemented a high-throughput GST calculation and compliance engine. The system extracts invoice-level line items, verifies HSN/SAC codes, checks statutory tax brackets, reconciles purchase registers directly against government portal registries via APIs, and flags mismatches before filing.

Architecture & Security Inquiries
Specific questions regarding this deployment's integration, data privacy, and exception handling.
How does the GST engine handle multi-state and exempt supplies?▾
The engine contains configurable tax rule tables that automatically determine whether a supply is inter-state (IGST), intra-state (CGST+SGST), or exempt based on vendor GSTIN and place of supply.
Can the engine process thousands of invoices simultaneously?▾
Yes, the batch processing engine uses parallel chunking to reconcile over 10,000 line items in under 3 minutes.
