Case Study: Indian Oil and Gas Company achieves GST compliance and automated SAP integration with Cygnet Infotech

GST Compliant SAP Integrated Solution For An Indian Oil And Gas Giant

Indian Oil and Gas Company, a large Indian oil and gas giant with operations across the hydrocarbon value chain, needed to transition from older tax regimes to GST while keeping its SAP ECC 6.0 environment compliant. The company faced challenges in determining the correct GST tax types and rates, handling point-of-supply mapping, managing exempt scenarios, preventing duplicate invoices, and ensuring mandatory GSTN data was available for filing. Cygnet Infotech was brought in to support the SAP-based GST integration.

Cygnet Infotech implemented a GST-compliant SAP integrated solution across SD, MM, FI and ABAP, migrating the client from TAXINJ to TAXINN and adding automated validation, invoice capture, reconciliation, dashboards, alerts, and multi-channel access through portal, mobile, APIs, and on-premise tools. The solution streamlined GSTR processing, improved GSTR-2A and purchase register matching, and supported diverse taxable scenarios for sales and purchases, including exports and imports. As a result, manual intervention was reduced by 80%, data security and compliance improved, and the client gained a scalable end-to-end solution for SAP-to-GSTN reporting and filing.
