The purpose of GST-HSN (Harmonized System of Nomenclature) in an ERP system is to classify goods and services under the correct HSN/SAC code to ensure accurate GST rate determination and statutory compliance. It enables the system to automatically calculate GST, display mandatory HSN/SAC details on invoices, and generate HSN-wise GST reports for return filing. GST-HSN helps prevent tax errors, supports audit traceability, and ensures compliance across purchase, sales, and service transactions.
