India GST Compliance Transformation
The Challenge
A pharmaceutical manufacturer operating across 10 plants and 14 states was processing roughly 45,000 invoices a month against India's statutory e-invoicing regime — and doing much of it by hand. Manual IRP submission consumed two to four hours daily per plant, invoices were being dispatched without a valid IRN, GSTR-2B reconciliation across 28,000 AP invoices took eight FTE-days every month, and E-Way Bills were tracked in Excel. HSN code data quality was a persistent blocker, with around 30% of codes blank.

Shvintech delivered an end-to-end SAP compliance architecture
SAP S/4HANA integrated through SAP BTP CPI, with SAP DRC Cloud Edition for statutory filing, a Datasphere ITC reconciliation model, and SAP Analytics Cloud for oversight. Three CPI iFlows carried the load:
Real-time IRN generation against the IRP for every outbound invoice.
Automated E-Way Bill generation and tracking, replacing the manual Excel process.
Scheduled GSTR-2B retrieval feeding the Datasphere ITC reconciliation model.
● HSN code data quality lifted from ~30% blank to 100% complete ● IRP rate-limit throttling at month-end resolved by redesigning 8,000-invoice batches with 14-GSTIN parallel processing ● GSTR-2B timing differences that were blocking ITC reconciled through the Datasphere model
Less than 8 min IRN automated, INR 24.8 Cr. ITC recovered in Year 1, Zero manual IRP submissions and Same-Day audit evidence
