Proforma Invoice Format India — What It Is, When to Use It & Free Template
A proforma invoice is a preliminary bill issued before a sale is confirmed — it is not a GST tax invoice and does not create a tax liability. Here is everything you need to know about proforma invoice format India, when to use one, and how it differs from a regular invoice.
A proforma invoice is one of the most commonly confused documents in Indian business. Many small business owners use the term interchangeably with 'estimate' or 'quotation' — but a proforma invoice has a specific meaning, especially in the context of exports and advance payments. Understanding when to issue a proforma invoice versus a tax invoice can save you from GST compliance errors.
What Is a Proforma Invoice?
A proforma invoice is a preliminary invoice sent to a buyer before goods are shipped or a service is delivered. It states the expected cost of the goods or services, quantity, and terms — but it is not a final tax invoice. A proforma invoice does not create a tax liability under GST and cannot be used by the buyer to claim Input Tax Credit (ITC).
Key distinction
A proforma invoice is an offer or estimate — it becomes a binding tax invoice only when the seller raises a formal GST tax invoice after delivery or payment. Do not use a proforma invoice as a substitute for a tax invoice in your GST returns.

What Must a Proforma Invoice Contain?

- Your business name, address, and GSTIN
- Buyer's name, address, and GSTIN (if applicable)
- Description of goods or services with quantity, unit price, and total
- Applicable GST rate and estimated tax amount (marked as indicative)
- Validity period (e.g., 'Valid for 30 days')

Is a proforma invoice the same as a quotation?
They are very similar — both are preliminary documents issued before a sale. The key difference is that a proforma invoice typically includes specific pricing, payment terms, and is used in more formal B2B or export contexts. A quotation is more commonly used in domestic service contracts and project bidding.
Can a proforma invoice be used for export customs clearance?
Yes. Indian customs and foreign buyers' customs departments accept proforma invoices for pre-shipment documentation. After the goods are shipped, you must raise a formal export invoice (commercial invoice) for the actual customs declaration.
Do I need to register a proforma invoice number in my GST returns?
No. Proforma invoices are not tax invoices and are not included in GSTR-1 or GSTR-3B. Only actual tax invoices, debit notes, and credit notes are reported in GST returns.
Can the buyer claim GST ITC on a proforma invoice?
No. Only a proper GST tax invoice can be used to claim Input Tax Credit. Proforma invoices, estimates, and quotations carry no ITC claim eligibility.
