GST done right, without thinking about it
Set your shop's state, GSTIN and GST scheme once. Every item carries its HSN or SAC code and GST rate.
When you bill a customer in your own state, The Ray splits tax into CGST and SGST. When the customer is in another state, it charges IGST instead. You never pick the tax type by hand.
Purchases record the input GST you paid, so the output and input sides of GST are both covered. At month end, GSTR-1 and GSTR-3B are laid out the way the GST portal organises them, ready to export for your CA.
Need a quick number? Our free GST calculator adds GST to a price or takes it out of an inclusive one, with the CGST, SGST and IGST split.
