Do you generate an IRN or file GSTR-1?

No. One Stop Invoice does not generate an IRN on the NIC portal and does not file GSTR-1. Use CA Sync to email a scheduled pack to your Chartered Accountant.

Is this useful if I'm not GST registered?

Yes. Create professional invoices without GST fields if you are below the registration threshold. Enable GST fields when you register - no migration needed.

Can I filter invoices by Indian Financial Year (April–March)?

Yes. Dashboard and reports follow the Indian FY (April–March). Filter by any FY and export data for your CA.

GST invoices, clients, debit notes, quotations, expenses, inventory, analytics, cloud storage, templates, and API access. No per-user charges.

GST invoicing software
for CGST, SGST, and IGST

Q: What is GST invoicing software?

GST invoicing software 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 reports on the Indian financial year (April–March).

Q: Does One Stop Invoice generate GST-compliant invoices?

Yes. Every invoice includes supplier and buyer GSTIN, HSN/SAC codes, place of supply, CGST/SGST/IGST breakdown, and sequential invoice numbering for B2B and B2C GST filing in India.

Q: How does CGST vs IGST get decided?

When you create an invoice, specify intra-state or inter-state supply. One Stop Invoice automatically applies CGST + SGST for intra-state and IGST for inter-state transactions.

Q: Can I validate my client's GSTIN before invoicing?

Yes. GSTIN format is validated in real time as you type, catching errors before the invoice is created.
