ISD & IMS Features in OptiGST
OptiGST empowers businesses with intelligent automation for both Input Service Distribution and Invoice Reconciliation through a unified, AI-enabled platform.
The ISD module identifies eligible purchases at the head office level and distributes Input Tax Credit (ITC) to branch units with distinct GSTINs under the same PAN based on turnover ratio. It auto-generates ISD Annexure and Challan and supports accurate, API-based GSTR-6 filing in compliance with GSTN guidelines.
The IMS Recipient Dashboard offers an AI-powered single-screen cockpit for end-to-end reconciliation. Users can extract and verify SAP purchase data, fetch invoices and GSTR data from the portal, and perform rule-based reconciliation with drill-down views. The system intelligently suggests actions (Accept/Reject/Pending), handles missing entries, and supports automated communication with vendors. Finalized records are stored and pushed to the portal with a single click.
Together, these features streamline GST compliance, reduce manual effort, and improve accuracy through smart automation.
