What is GST invoicing software?
GST invoicing software is an application that creates GST-compliant tax invoices for Indian businesses: it splits CGST and SGST or IGST from place of supply, checks GSTIN format, prints HSN or SAC and the amount in lakh and crore, and reports on the Indian financial year (April–March). One Stop Invoice is GST invoicing software. It also stores clients, inventory, and expenses, and can email a scheduled pack to your Chartered Accountant. It does not generate an IRN on the NIC portal and it does not file GSTR-1. Free to start, no credit card. A watermark and a monthly document limit of 20 apply until you unlock at ₹1,499/year or ₹199/month (GST included). No per-user fees.
