When purchasing products or services, you may encounter two similar-looking documents: a proforma invoice and an invoice. Although they often contain similar information, they serve different purposes and have different legal implications.
Understanding the difference between these documents is important for both businesses and individual customers.

What Is a Proforma Invoice?
A proforma invoice is a preliminary document issued before a sale is completed. It informs the customer about the products or services being offered, their prices, payment terms, and other transaction details.
A proforma invoice is not an accounting document and does not confirm that a sale has taken place. It is commonly used as:
- A quotation or price offer
- A request for advance payment
- An order confirmation
- A document used during international trade transactions
Because a proforma invoice does not document an actual sale, it cannot usually be used for accounting or tax purposes.
What Is an Invoice?
An invoice is an official accounting document issued after a product or service has been sold. It confirms that a transaction has taken place and specifies the amount owed by the buyer.
Depending on local regulations, an invoice may include:
- Invoice number
- Issue date
- Seller and buyer details
- Description of products or services
- Quantity and unit prices
- Tax information
- Total amount due
- Payment deadline
Invoices are used for bookkeeping, tax reporting, and financial settlements.
Key Differences Between a Proforma Invoice and an Invoice
| Proforma Invoice | Invoice |
|---|---|
| Preliminary document | Official accounting document |
| Issued before the sale is completed | Issued after the sale or service |
| Does not create a tax obligation | May create a tax obligation depending on local regulations |
| Cannot usually be used for accounting purposes | Used for accounting and tax records |
| Often used to request payment | Confirms payment is due or has been requested |
| Does not prove a transaction occurred | Confirms a transaction took place |
When Should a Proforma Invoice Be Used?
A proforma invoice is commonly used when:
- Requesting payment before delivery
- Preparing custom orders
- Selling products internationally
- Providing customers with a detailed quotation
- Confirming order details before issuing a final invoice
When Should an Invoice Be Used?
An invoice should be issued when:
- Goods have been sold
- Services have been provided
- A transaction must be recorded for accounting purposes
- Tax regulations require transaction documentation
Summary
While a proforma invoice and an invoice may look similar, they serve different purposes. A proforma invoice is an informational document used before a transaction is completed, while an invoice is an official financial document that confirms a sale and can be used for accounting and tax purposes.
Businesses often use proforma invoices to provide payment information before delivery, then issue a final invoice once the transaction has been completed.
