What is a Proforma Invoice?
A Proforma Invoice is a preliminary commercial document issued by a seller to a buyer before goods are supplied or services are delivered. It provides an estimate of the products, services, pricing, taxes, shipping charges, and payment terms that will appear on the final invoice.
Unlike a tax invoice, a proforma invoice is not a demand for payment and does not create an accounting transaction. Instead, it serves as a quotation in invoice format, helping buyers understand costs before placing an order.
Businesses across India use proforma invoices for domestic sales, exports, custom orders, project-based services, advance approvals, and international trade transactions.
Why Businesses Use Proforma Invoices
A proforma invoice helps both buyers and sellers establish clarity before a transaction is finalized.
- Provides detailed cost estimates before confirming an order.
- Helps customers secure internal approvals and budgets.
- Reduces misunderstandings regarding pricing and taxes.
- Supports import-export documentation requirements.
- Allows sellers to communicate terms before issuing a tax invoice.
- Improves transparency in B2B transactions.
When Should a Proforma Invoice Be Issued?
1. Before Confirming a Sales Order
Many businesses issue a proforma invoice after price negotiations but before order confirmation.
| Stage | Document Used |
|---|---|
| Price Discussion | Quotation |
| Order Approval | Proforma Invoice |
| Supply of Goods | Tax Invoice |
2. For Advance Payments
Businesses often send a proforma invoice before collecting advance payments from customers.
3. For Import and Export Transactions
International buyers frequently require a proforma invoice to obtain import licenses, arrange financing, calculate duties, or complete customs documentation.
4. For Custom Manufacturing Orders
When products are manufactured according to customer specifications, a proforma invoice helps document agreed pricing and requirements before production begins.
5. For Service-Based Projects
Consultants, agencies, software companies, and contractors use proforma invoices to communicate project costs before commencing work.
Is a Proforma Invoice Valid Under GST?
Yes, businesses can issue proforma invoices under GST for quotation and estimation purposes.
However, a proforma invoice:
- Is not a GST tax invoice.
- Does not create GST liability.
- Cannot be used to claim Input Tax Credit (ITC).
- Cannot be reported in GST returns.
- Must be replaced by a valid tax invoice when the supply occurs.
GST becomes applicable only when the actual supply takes place and a tax invoice is issued.
