📖 Frequently Asked Questions (FAQ)

A GST Invoice is a legal document issued by a seller to the buyer containing details of the sale, tax rates, and the amount of GST charged. It serves as proof of a taxable supply of goods/services under the Goods and Services Tax (GST) law.

A Proforma Invoice is a preliminary bill issued before the final sale. It is not a legal tax invoice but provides an estimated cost of goods/services. It is often used for quotations or customs purposes.

To generate a GST invoice, follow these simple steps:

  1. Enter Seller & Buyer Details (Name, GSTIN, Address).
  2. Add Invoice Number & Date.
  3. List the Items Sold (HSN Code, Quantity, Price, GST Rate).
  4. Calculate CGST, SGST, or IGST.
  5. Click “Generate Invoice” and print or save it as PDF.

GST stands for Goods and Services Tax. It is a single tax applied on the supply of goods and services across India, replacing multiple indirect taxes like VAT, Service Tax, and Excise Duty.

Any registered business under GST law must issue a GST invoice for taxable sales. This applies to traders, manufacturers, service providers, and businesses with annual turnover above ₹20 lakhs (₹10 lakhs for special category states).

GST is calculated using the formula:

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

For example, if a product costs ₹1,000 and GST is 18%, the GST amount will be:

₹1,000 × 18% = ₹180

There is no minimum amount for issuing a GST invoice. However, for sales below ₹200, a consolidated invoice can be issued instead of separate invoices for each sale.

There are three types of GST in India:

  • CGST – Central Goods and Services Tax (collected by the central government).
  • SGST – State Goods and Services Tax (collected by state governments).
  • IGST – Integrated Goods and Services Tax (collected for interstate transactions).

Yes! You can create your own invoice manually or using GST invoice generator tools. However, a GST invoice must follow the government-prescribed format, including:

  • Seller & Buyer GSTIN
  • Invoice Number & Date
  • HSN Code & Tax Rates
  • CGST, SGST, or IGST Amount
  • Total Invoice Value

You can claim a GST refund if:

  • You export goods/services (zero-rated supply).
  • You paid excess tax due to miscalculation.
  • You received a refund order from GST authorities.

To claim, log in to the GST portal, fill Form RFD-01, and submit supporting documents.

GST is paid by the end consumer. However, businesses act as collectors and deposit the collected tax to the government. Some businesses under Reverse Charge Mechanism (RCM) pay GST directly.
