Proforma Invoice for Export: Format, Mandatory Fields and Common Mistakes
The proforma invoice is the first document your buyer sees, and the one their bank uses to open a letter of credit or release an advance. Here is what it must contain, how it differs from a commercial invoice, and the errors that come back to haunt the shipment.

Quick facts
- A proforma invoice is a quotation in invoice form: it confirms what will be supplied, at what price and on what terms, before the goods are shipped.
- It is not a demand for payment and is not used for customs clearance of the export shipment.
- Buyers use it to arrange an advance payment, open a letter of credit or apply for an import licence or foreign-exchange approval in their country.
- Every figure on it — description, quantity, price, Incoterm, payment terms — should carry through unchanged to the commercial invoice.
- A mismatch between the proforma and the LC or commercial invoice is a common cause of LC discrepancies and payment delays.
- Give it a number, a date and a validity period, and revise it with a new version number rather than editing the old one.
A proforma invoice for export is a preliminary invoice the exporter sends before shipment, stating the goods, quantities, prices, Incoterm, payment terms and delivery time. The buyer uses it to pay an advance, open a letter of credit or obtain an import licence. It is not a tax invoice and does not replace the commercial invoice used for customs and payment.
This guide covers the fields a proforma invoice needs, how it differs from the commercial invoice, and the small mistakes that become expensive once a letter of credit is opened against it. ExportCRM wrote it for exporters who prepare these every week.
What a proforma invoice is used for
A proforma invoice tells the buyer exactly what they will receive and pay before anything is shipped. Its main uses are: confirming the commercial terms of an order, letting the buyer pay an advance, giving the buyer's bank the details to open a letter of credit, and supporting import licence or foreign-exchange applications in countries that require them.
Because the buyer's bank may copy the proforma's wording into the letter of credit, anything vague or wrong on the proforma tends to reappear as an LC term you then have to meet exactly. That is why it is worth preparing as carefully as the commercial invoice.
Proforma invoice format: the fields to include
| Section | Fields |
|---|---|
| Header | Words "Proforma Invoice", PI number, date, validity date, version number if revised |
| Exporter | Legal name, address, IEC, GSTIN, contact person, email, phone |
| Buyer and consignee | Buyer name and address; consignee if different; notify party if known |
| Goods | Item description, HS code, quantity, unit, unit price, line total, packing details |
| Commercial terms | Currency, Incoterm with named place (e.g. FOB Nhava Sheva), payment terms, delivery or shipment period |
| Shipping | Port of loading, port of discharge, final destination, mode (sea/air), partial shipment and transhipment allowed or not |
| Bank details | Beneficiary name, bank, account number, SWIFT code, and AD code details if requested |
| Totals | Subtotal, freight and insurance if CIF/CIP, total amount in figures and words |
| Terms | Tolerance on quantity (e.g. ±5%), inspection, warranty, governing terms, signature |
Keep the description specific enough that the same text can be used on the commercial invoice, packing list and shipping bill. A product called "cotton fabric" on the proforma and "100% cotton woven fabric, 140 cm, dyed" on the commercial invoice invites questions from the buyer's bank and from customs.
Proforma invoice vs commercial invoice
| Proforma invoice | Commercial invoice | |
|---|---|---|
| When | Before the order is confirmed or produced | At shipment |
| Purpose | Confirm terms; advance; LC; import licence | Customs, payment, incentives, accounting |
| Legally a demand for payment? | No | Yes |
| Used for customs clearance? | No | Yes |
| Can change? | Yes, with a new revision | Should match goods actually shipped |
The commercial invoice should normally follow the proforma line for line. When the final shipment differs — a partial shipment, a changed quantity within tolerance — the difference should be explainable from the proforma and any amendment, not a surprise.
Mistakes that cause trouble later
- Incoterm without a named place. "FOB" alone is incomplete; write "FOB Mundra, India" (Incoterms® 2020).
- No tolerance on quantity. If you cannot ship exactly 10,000 pieces, say ±5% on the proforma so the LC allows it.
- Wrong beneficiary name. The beneficiary on the LC must match your bank account and invoices exactly.
- Unrealistic shipment date. The LC's latest shipment date usually comes from the proforma; leave room for production and booking.
- Editing a sent proforma. Issue PI-123 Rev 1 instead, so everyone knows which version the LC was based on.
- Different units on different documents. If the proforma says pieces, the invoice and packing list should not switch to dozens.
Making proforma invoices faster and consistent
Most exporters build proformas in Excel or Word, then retype the same data into the commercial invoice and packing list. That is where mismatches start.
In ExportCRM a proforma is created from the lead or quotation, and when the buyer confirms, the same record becomes the order — so the commercial invoice and packing list are generated from the data the buyer already approved. Revisions are versioned, and multi-currency totals use the current DGFT exchange rate. See proforma invoice software.
Frequently asked questions
What is a proforma invoice in export?
It is a preliminary invoice sent before shipment that sets out the goods, quantities, prices, Incoterm, payment terms and delivery time. The buyer uses it to pay an advance, open a letter of credit or apply for an import licence.
Is a proforma invoice a legal document?
It is not a demand for payment or a tax invoice, but once the buyer accepts it — especially if an LC is opened on it — its terms effectively become the agreed terms of the sale, so it should be accurate.
Is a proforma invoice needed for customs clearance?
No. Indian customs clears exports on the commercial invoice, packing list and shipping bill. The proforma is a pre-sale document.
Can the commercial invoice differ from the proforma invoice?
It should match unless the order was formally amended. Small differences allowed by agreed tolerances are fine; unexplained differences cause problems with LCs and buyers.
Should GST be shown on an export proforma invoice?
Exports are zero-rated. The proforma usually shows the foreign-currency price without GST; the GST treatment (LUT or IGST paid) is reflected on the export tax invoice at shipment.
How long should a proforma invoice be valid?
Most exporters state 15 to 30 days, depending on how volatile raw material prices and exchange rates are. State the validity clearly on the document.
