The problem

What the customer was facing.

GST compliance spanned multiple state registrations, and preparing sales and purchase data for GSTR filings was a slow, error-prone manual exercise. Invoice matching for GSTR-2 reconciliation was the worst of it — vendor discrepancies surfaced late, ITC slipped, and filings consistently missed the comfortable end of the deadline.

How we engaged

The approach we ran.

We built a configuration-driven GST integration inside Oracle NetSuite covering GSTR-1, GSTR-3B, and GSTR-2 reconciliation. Zero hardcoded logic: the integration reads NetSuite’s data structures dynamically, so it absorbs future ERP-config changes without a rebuild. Automated validation catches discrepancies before filing, not after.
