Proforma invoice is like a preparation for the sale. Before the sale, business needs to share the prices, product details and other product related information. Proforma invoice helps them add those details into the sheet before the final invoice.
It is commonly used in international trade, but it can also be useful for local sales, advance payments, and large orders.
What is a Proforma Invoice?
A proforma invoice is a document a seller sends to a buyer before a sale is completed. It shows the expected cost of goods or services, along with important details such as quantities, delivery conditions, and payment terms.
The meaning of a proforma invoice is quite simple. It gives the buyer an idea of what they will receive and how much they may need to pay.
Unlike a regular invoice, a proforma invoice is not usually a request for payment for a completed sale. It is closer to a detailed price quotation.
How Does a Proforma Invoice Work?
It starts with a client or potential client asking for a price. Let’s say a customer approach you to buy 500 pieces of shirts from you and asks for a price, you prepare a proforma invoice showing the product details, shipping costs, payment conditions and other details that are completing the process.
Then customers review the document and decide whether to buy. If sale happens, invoice happens as a next stage. This makes the buying process clearer for both parties.
When to Use a Proforma Invoice?
Businesses use proforma invoices in several situations.
International Trade and Customs Clearance
Importers and exporters often need a proforma invoice before goods are shipped. It helps buyers estimate costs and arrange shipping or import documents.
However, customs authorities may require a commercial invoice or other documents for final clearance.
Advance Payments and Prepayments
Some suppliers ask customers to pay before production or shipping starts.
A proforma invoice shows what the payment covers. This is particularly helpful when products are made to order.
Import Licenses and Letters of Credit
Importers may need a proforma invoice when applying for an import license or arranging trade finance.
Banks may use its information during the application process. However, a proforma invoice cannot normally replace the commercial invoice required under a letter of credit unless the terms specifically allow it.
Price Quotes and Sales Agreements
When customers need detailed pricing, a proforma invoice is often more useful than a simple quote.
It brings product descriptions, delivery costs, and payment terms together in one document.
What Should a Proforma Invoice Include?
There is no single format of a proforma invoice used by every business. Still, most documents include these details:
- Seller and buyer details: Business names, addresses, and contact information.
- Proforma invoice number and issue date: A reference number and the date the document was created.
- Description, quantity, and unit price: Details of the goods or services being offered.
- Estimated total amount: Product costs, applicable taxes, shipping fees, and the total price.
- Payment terms and validity period: Accepted payment methods, deadlines, and how long the offer remains valid.
- HS codes and country of origin: Important product information for international shipments.
Adding clear details helps prevent misunderstandings later.
Format of a Proforma Invoice
A good proforma invoice should be simple to read.
Place the seller’s information at the top, followed by the buyer’s details and invoice number.
Use a table to show products, quantities, and prices. Below the table, include shipping charges, taxes, and the estimated total.
Finally, add payment and delivery terms.
Make sure the document is clearly titled “Proforma Invoice” so nobody mistakes it for a final tax invoice.
How to Create a Proforma Invoice? (Step-by-Step)
You don’t need complicated software to prepare a proforma invoice. A basic template or invoicing tool is usually enough.
Step 1: Confirm Order Details With the Buyer
Check what the customer wants to purchase, including quantities, product specifications, and delivery location.
Step 2: Add Seller and Buyer Information
Enter both companies’ names, addresses, and contact details. Include tax identification numbers where needed.
Step 3: List Goods or Services With Estimated Prices
Add each product or service, its quantity, unit price, and total amount.
Make sure the prices match the offer discussed with the customer.
Step 4: Specify Taxes, Shipping and Payment Terms
Include any estimated taxes, delivery charges, and payment conditions.
For international orders, mention the currency and agreed shipping terms.
Step 5: Clearly Mark the Document as “Proforma Invoice”
Write “Proforma Invoice” at the top. You can also add “Not a Tax Invoice” to avoid confusion.
Step 6: Send to the Buyer and Convert to a Final Invoice After Shipment
Send the document for review. Once the sale moves forward, issue the required commercial or tax invoice at the appropriate time.
This may be before or after shipment, depending on the transaction and local rules.

Proforma Invoice vs Commercial Invoice: Key Differences
Although these documents look similar, they serve different purposes.
| Proforma Invoice | Commercial Invoice |
| Issued before the sale is finalized | Issued for an actual sale |
| Shows proposed or estimated amounts | Shows confirmed transaction amounts |
| Used for quotations and planning | Used for billing, accounting, and trade documentation |
| Not normally a tax invoice | May serve as a tax invoice if legal requirements are met |
| Usually does not record a completed sale | Records the actual transaction |
In simple terms, a proforma invoice explains what the buyer is expected to purchase. A commercial invoice records what is actually sold.
Is a Proforma Invoice Legally Binding?
A proforma invoice is generally not legally binding by itself.
It is usually an offer or estimate rather than a final sales document.
However, if the buyer accepts its terms, it may become part of a binding agreement. This depends on the contract and applicable law.
Businesses should therefore make sure all prices and conditions are correct before sending one.
Do Proforma Invoices Fall Under e-Invoicing Mandates?
Generally, proforma invoices are not covered by the same e-invoicing requirements as official tax invoices because they do not normally record completed sales.
However, rules depend on the country and the type of transaction.
For example, e-invoicing in Europe is developing through national regulations and EU-wide changes. Businesses must check which documents need to be issued electronically.
A proforma invoice does not normally replace a compliant electronic invoice.
For proper tax compliance, businesses should also distinguish proforma invoices from commercial invoices and transport documents such as an e-waybill.
FAQs About Proforma Invoices
Can you pay against a proforma invoice?
Yes. A buyer can make an advance payment based on a proforma invoice if both parties agree. The seller must still issue the required final or tax invoice according to local rules.
Does a proforma invoice include VAT?
A proforma invoice may show estimated VAT when applicable. However, showing VAT does not make it a valid VAT invoice.
Can a proforma invoice be used for VAT deduction or bookkeeping?
Normally, no. A proforma invoice alone is not sufficient for VAT deduction or recording a completed purchase. Businesses generally need a valid tax invoice and appropriate supporting records.
Can a proforma invoice be changed after it is issued?
Yes. Since it is usually a preliminary document, the seller can update prices, quantities, or delivery details before the final sale. Changes should be communicated to the buyer.
How long is a proforma invoice valid?
There is no universal validity period. The seller can set a deadline, such as 15 or 30 days, depending on pricing and business conditions.
A clear validity date helps both parties understand how long the offer remains available.
