For any business to conduct its operations in a GST compliant fashion, it is important to be aware of the HSN / SAC codes of the goods and services that it deals in, and also the corresponding GST rates. Given the extensive list of goods and services which have been classified as taxable supplies under GST, it may not be feasible for a business, at least in the transition phase, to operate by committing the rates and codes to memory and use them appropriately while raising a GST invoice . And the GST rate finder is one such tool in such direction.
