Step-by-step GST invoice process

  1. Add your business name, address, contact details, and GSTIN.
  2. Add the buyer name, address, and GSTIN if available.
  3. Enter invoice number, invoice date, due date, and place of supply.
  4. Add each product or service with description, HSN/SAC, quantity, and rate.
  5. Choose the right GST mode: CGST + SGST for same-state billing, IGST for interstate billing.
  6. Preview the invoice, check totals, and save the PDF.

Common mistakes to avoid

  • Using IGST for a same-state sale by mistake.
  • Leaving place of supply blank on a GST invoice.
  • Forgetting HSN/SAC details when they are needed for your business.
  • Sending a quotation as if it were a final tax invoice.
