📖 Frequently Asked Questions (FAQ)

A GST invoice is a legal document issued by a seller to a buyer showing sale details, GST rate, and GST amount charged. It serves as proof of taxable supply under GST law.

A proforma invoice is a preliminary bill issued before the final sale. It’s not a tax invoice, but an estimated cost used for quotations or customs.

  1. Enter seller & buyer details (name, GSTIN, address).
  2. Add invoice number & date.
  3. Add items (HSN/SAC, qty, rate, GST%).
  4. Calculate CGST/SGST or IGST.
  5. Generate and print / save as PDF.

GST means Goods and Services Tax — a single tax on supply across India that replaced multiple indirect taxes like VAT, Service Tax, and Excise Duty.

GST-registered businesses must issue GST invoices for taxable sales (traders, manufacturers, service providers). Thresholds generally apply (often ₹20L / ₹10L for special category states).

GST Amount = (Original Price × GST Rate) / 100

Example: ₹1,000 at 18% GST → GST = ₹180

Use our GST Calculator to split CGST/SGST/IGST quickly.

There is no minimum amount. For sales below ₹200, a consolidated invoice can be issued instead of separate invoices.

  • CGST – Central GST (centre)
  • SGST – State GST (state)

  • Invoice number & date
  • HSN/SAC + tax rates
  • CGST/SGST/IGST amount
  • Total invoice value
  • Exports (zero-rated supply)

To claim: GST portal → Form RFD-01 + supporting documents.

GST is borne by the end consumer. Businesses collect it and deposit to the government. Under RCM, some GST is paid directly by the recipient.

At the time of supply. For goods: delivery/transfer. For services: completion (as per GST time-of-supply rules). Prompt invoicing improves compliance.

A unique consecutive serial number (max 16 characters). It can include alphabets, digits, and separators like dash or slash and must be unique for the financial year.

It provides legal proof of supply, helps buyer claim input tax credit (if eligible), and supports transparent, compliant business records.

GST invoices for business purchases can help claim eligible input tax credit, potentially reducing effective procurement cost.

It lists goods/services, quantity, taxable value, GST rate (CGST/SGST/IGST), and total payable—helping both seller and buyer track transactions for GST compliance.

Discounts before/at sale reduce taxable value. Post-sale discounts must be linked to the invoice and agreed by both parties, as per GST rules.

Once issued, it shouldn’t be altered. Corrections are typically done via a credit note or debit note, as applicable.
