Any tax-based transaction that happens within the state (Intrastate) then CGST & SGST were applicable. Any tax-based transaction that happens across the state (Interstate) then IGST was applicable. Also, under the new tax policy, the government had allowed all the Registered taxpayers to offset their output liabilities (Revenue) with their input tax Credits (Suppliers Invoices).
The new GST law insisted only on the chargeability of Taxes on the sale/purchase of goods & Services and there was no restriction imposed on any movements of goods & services across states. Hence Hathway business entity had to undergo a few minor changes in their business process. It was also prudent that the modifications had to be done on all applications (including Financials systems) wherever the business transactions are generated. Hathway accounted for all their transactions in various systems.
Oracle ERP EBS was the financial system used by Hathway as a single source of truth for their financial reporting. Other systems viz. OBRM, MQ, UPAAS, and Hathway Connect were used for other tasks like billing on individual Customers, generating invoices, and receipts for collections. All these transactions were updated on the Oracle EBS at regular intervals on a consolidated basis or as individual entries.
Due to the introduction of GST Policies, all these systems had to be changed to accommodate the GST requirements.
