Pro Forma vs Commercial Invoice: Differences

A pro forma invoice is a preliminary invoice sent before goods or services are delivered. It states what the final invoice is expected to look like but it is not a demand for payment. A commercial invoice is the final, legally relevant invoice for a sale, and for international shipments it is also the document customs authorities use to value the goods.

Quick answer: Pro forma = “this is what the invoice will be” (before delivery, not a bill). Commercial invoice = “this is what you owe” (after or at delivery, and the document used for customs in international trade).

Pro forma vs commercial invoice at a glance

	Pro forma invoice	Commercial invoice
Issued	Before shipment or delivery	At or after shipment or delivery
Purpose	Quote, confirm order details, obtain advance payment, prepare customs or import licences	Request payment and declare the sale to customs
Is it a bill?	Not a final demand for payment	Yes, a real invoice
Accounting entry	Not recorded as a sale	Recorded as a sale and a receivable
Tax invoice?	No	It can serve as one if it has the required details
Binding?	Not on its own	Records the completed sale
Marked as	“Pro forma invoice”	“Invoice” or “Commercial invoice”

What is a pro forma invoice?

“Pro forma” is Latin for “as a matter of form”. A pro forma invoice looks like an invoice but is marked as a preliminary document. It tells the buyer exactly what they would be charged, based on the order as it currently stands. Sellers use it in situations like these:

1. International orders. The buyer needs a document to apply for an import licence, arrange a letter of credit or obtain foreign currency from a bank.
2. Advance payment. The seller wants payment before producing or shipping, and the buyer needs a document to support the transfer or to get internal approval.
3. Customs. For samples, gifts and goods shipped without a sale, a pro forma invoice shows value for customs even though no money changes hands.
4. Quote confirmation. The buyer wants to see the final price, including delivery and taxes, before committing.
5. Budget approval. A buyer’s finance team needs a document before it can raise a purchase order.

Because it is preliminary, a pro forma invoice should say so clearly: for example “This is a pro forma invoice. It is not a request for payment and is issued for information and customs purposes.” Many businesses also include a validity date, since prices and exchange rates move.

What is a commercial invoice?

A commercial invoice is the invoice that records a completed sale between a seller and a buyer. In domestic trade, people simply call it an invoice. In international trade, “commercial invoice” is a specific document that accompanies a shipment, usually in multiple copies, and is used by customs authorities to:

• Verify the value of the goods for duties and taxes
• Identify the goods and their classification
• Confirm origin, parties and terms of sale

Customs rules differ by country, but a typical commercial invoice includes the seller and buyer names and addresses, the date, an invoice number, a full description of goods, quantities, unit prices and total value, the currency, the Incoterms (shipping terms), the country of origin and shipping details.

What a pro forma invoice should contain

A pro forma invoice is judged by whether the person who receives it can act on it: raise a purchase order, apply for a licence, pay an advance or clear a sample through customs. That means it needs nearly everything a final invoice has, plus a few items that make its preliminary status unmistakable.

Item	Why it matters
The words “Pro forma invoice” in the title	Prevents it being mistaken for a final bill
A statement such as “not a request for payment”	Protects both sides from double payment
Pro forma number	Lets you refer to it later on the commercial invoice
Issue date and validity date	Prices and exchange rates change, so say how long it holds
Seller and buyer names, addresses, tax or registration numbers	Banks and customs often ask for them
Full description of goods or services	Needed for licences, finance and classification
Quantity, unit price, line totals	Lets the buyer check the arithmetic
Currency	Avoids disputes over which currency is meant
Estimated freight, insurance, packing, taxes	The buyer wants the landed cost, not only the goods
Incoterms and delivery place	Defines who pays and who carries the risk
Payment terms and bank details	Shows how an advance should be paid
Country of origin and reason for issue (if relevant)	Often requested for customs and samples

You do not need to fill every row for every use. A pro forma sent only to confirm a domestic price can be shorter. A pro forma sent to a bank for a letter of credit should be as complete as you can make it.

What a commercial invoice should contain for customs

A commercial invoice has two readers: the buyer, who pays it, and customs, who values the goods with it. Customs officers are looking for consistency. The description should match the goods in the box, the quantity should match the packing list, and the value should match what was really paid or is payable.

Item	Notes
Title “Commercial invoice”	Distinguishes it from a pro forma or a sample invoice
Invoice number and date	Unique, sequential and traceable
Exporter and consignee details	Full legal names and addresses, with tax or customs identifiers where required
Description of goods	Plain, specific language: “men’s cotton shirts, woven” rather than “clothing”
Tariff classification (HS code)	The first six digits are international; your country adds more
Quantity and unit of measure	Pieces, kilograms or metres, matching the packing list
Unit price and total value	In one stated currency
Country of origin	Where the goods were made, not where they were shipped from
Incoterms and place	For example DAP Toronto or FCA Rotterdam
Freight and insurance	Shown separately, so customs can value the goods correctly
Reason for export	Sale, sample, gift, repair or return
Signature and declaration	Many authorities expect a signed statement that it is true and correct

Some countries also require extra statements, language requirements or specific forms. A freight forwarder or the customs authority’s website for the importing country is the safest source of the final list.

Incoterms in plain language

Incoterms are standard three-letter trade terms published by the International Chamber of Commerce. They say who arranges and pays for transport and insurance, and at which point the risk passes from seller to buyer. They belong on both the pro forma and the commercial invoice, because they change the numbers on the page.

Term	Rough meaning	Who pays main carriage
EXW	Buyer collects from the seller’s premises	Buyer
FCA	Seller hands over to the buyer’s carrier at a named place	Buyer
FOB	Seller loads the goods on board the ship (sea freight only)	Buyer
CFR	Seller pays freight to the destination port, risk passes at loading	Seller
CIF	As CFR, plus seller buys minimum insurance	Seller
CPT	Seller pays carriage to a named place	Seller
DAP	Seller delivers to the named place, ready for unloading	Seller
DDP	Seller delivers and also pays import duties and taxes	Seller

If you are a small exporter, DAP and FCA are common starting points because they are easy to price. DDP can be attractive to buyers but puts import duties and local compliance on you, so it needs more care. Always write the term with a named place, such as “DAP Toronto”, because the place is part of the term.

Key differences explained

1. Timing

A pro forma comes first, a commercial invoice comes with the shipment or after delivery.

2. Legal status

A pro forma is not normally treated as a demand for payment and is not a tax document. A commercial invoice is a record of sale and, in many countries, a tax document.

3. Accounting treatment

You do not record a pro forma as revenue. You record revenue on the commercial invoice (or according to the applicable accounting rules). A buyer should not pay a pro forma twice: once in advance, and again on the final invoice. The final invoice should credit the advance payment.

4. Changes

A pro forma may change if the order changes. A commercial invoice should match the actual shipment and prices.

From enquiry to delivery: how the documents fit together

It helps to see the documents in order, because the pro forma and commercial invoice are only two points on a longer path. The steps below describe a typical export of goods that are made or bought to order.

1. Enquiry. The buyer asks for a price. You answer with a quote or a price list.
2. Order confirmation. The buyer accepts. You confirm quantities, price, delivery term and payment terms in writing.
3. Pro forma invoice. You issue a pro forma with the confirmed details. The buyer uses it to arrange funds, licences or internal approval.
4. Advance payment. If agreed, the buyer pays a deposit or the full amount against the pro forma. You record the receipt and, where required, issue a receipt or an advance invoice.
5. Production and packing. You make or pick the goods and prepare a packing list showing cartons, weights and dimensions.
6. Shipment. The carrier issues a transport document, such as a bill of lading or air waybill.
7. Commercial invoice. You issue the final invoice that matches the shipment, deducts any advance and carries its own number.
8. Customs clearance. The buyer or their broker presents the commercial invoice, packing list and transport document.
9. Balance payment. The buyer pays whatever remains under the agreed terms.

Notice that the numbers should carry through. The pro forma gives an estimate, the order confirmation fixes it, and the commercial invoice records what was actually shipped. If the quantity changes because of a short production run, the commercial invoice follows reality and the difference is explained, ideally by a short email that you keep with the file.

Tax and accounting treatment of advance payments

A pro forma invoice by itself is not an accounting event. You do not record revenue, you do not charge tax on it, and it does not appear in your sales ledger. Money is a different matter. When the buyer pays an advance against a pro forma, you have received cash for goods you have not yet delivered.

• Bookkeeping. Most small businesses record the advance as a customer deposit or unearned revenue, a liability, until the goods are delivered.
• Sales tax and VAT. In many VAT systems, tax becomes due when you receive an advance payment or issue an invoice, even before delivery. Rules differ, so confirm with your tax adviser or authority.
• Documents. Where required, you may issue a receipt or an advance payment invoice for the amount received. The final invoice should then show the full value and subtract what has been paid, so that the net amount due is correct.
• Export zero-rating. Some jurisdictions apply a zero rate or an exemption to exports, but they usually require proof of export. Keep the commercial invoice, transport document and customs records.

This is a general description only, not tax advice. The rules depend on the country, the goods and whether the buyer is a business.

Samples, gifts and returns

Pro forma invoices are used for shipments that are not sales. Customs still needs a value, a description and a reason for the shipment, even when no one is paying.

Shipment	What to show	Typical wording
Free samples	Real or estimated value, “no commercial value” where allowed	“Samples, no commercial value, not for resale”
Gifts	Value of the goods and a clear gift statement	“Gift, value for customs purposes only”
Goods for repair	Value and the intention to return	“Returned after repair, no sale”
Goods for an exhibition	Value, temporary export or import	“Temporary export, to be returned”
Returned goods	Original invoice reference and reason	“Return of goods, original invoice 0112”

Be accurate. Understating the value of a shipment to reduce duties or delay is a serious offence in many places, and it can lead to seized goods, fines and trouble with future shipments. The value you declare should be what you would charge for the goods, even if you are giving them away.

Wording that avoids confusion

The most common problems with pro forma invoices are not legal. They are misunderstandings: a buyer pays twice, a customs officer treats a pro forma as a final invoice, or an accountant records a sale that never happened. Clear wording prevents almost all of them.

Place	Suggested wording
Title	“PRO FORMA INVOICE” in capitals, never just “Invoice”
Under the title	“This is not a request for payment unless stated”
Validity	“Valid until 12 November 2026. Prices may change after this date.”
Advance	“50% advance requested on order confirmation to start production.”
Link to the final invoice	“A commercial invoice will be issued at shipment. Any advance will be deducted.”
Customs	“Issued for customs and licensing purposes only.”
Samples	“No commercial value. Samples for evaluation only.”

Keep the pro forma number and the commercial invoice number separate, and refer to the first from the second: “Pro forma PF-0007, advance received 2 November: $2,085.00.” That reference gives the buyer’s accounts team a clear trail.

Digital copies, signatures and stamps

International trade still relies on paper habits, and some banks, agents or customs offices expect a signed or stamped copy. Many accept a PDF with a typed name and date, but not all do. If you are told a signature is needed, sign the printed copy and scan it, or add an electronic signature if the recipient accepts it. Always keep the same version in your records that you sent.

Working out the numbers: a landed-cost example

A pro forma is most useful when the buyer can see the total cost of getting the goods to their door. Here is how the numbers for the wallet order above could be built, so that the pro forma total is not a guess.

Line	Basis	Amount (USD)
Goods	200 wallets at $18.00	3,600.00
Export packing and labelling	Flat charge	150.00
Subtotal, ex works		3,750.00
Freight to Toronto	Quote from forwarder, 2 cartons	420.00
Insurance	0.5% of goods and freight, rounded	21.00
Estimated total, DAP Toronto		4,191.00
Import duty and taxes	Paid by the buyer on arrival	Not included

Two points matter here. First, the “estimated” label is honest: the freight was quoted, not yet booked. Second, the document says clearly which costs are included and which are not. If you were quoting DDP instead, the duty and tax line would move into your total, and you would need to check the rates before you promise a price.

How long should a pro forma stay valid?

There is no fixed rule, but the validity should reflect how fast your costs move. Thirty days is common for physical goods. For goods tied to volatile commodity prices or currencies, 7 to 14 days is safer. Always print the date in full, such as “Valid until 12 November 2026”, so nobody has to count days from an issue date.

What if the buyer asks for changes?

Treat a changed order as a new pro forma. Issue a revised document with a new number or a revision suffix, such as PF-0007-R1, and mark the earlier one as superseded. This avoids two documents with different totals both looking current, which is a common cause of overpayment and customs queries.

When should you use each?

Situation	Use
A buyer wants to see the final price before agreeing	Quote or pro forma invoice
A buyer needs paperwork to arrange import licences or finance	Pro forma invoice
You want payment before you start production	Pro forma invoice, then an invoice for the advance (check local rules)
Shipping samples with no sale	Pro forma invoice, marked “no commercial value” where applicable
Goods are shipped and sold	Commercial invoice
A domestic sale	Standard invoice

Pro forma vs quote vs proposal

A quote is a price offer that may become binding when accepted. A pro forma invoice is shaped like an invoice and often confirms an order that is already agreed. They overlap, and in many industries they are used interchangeably. If your buyer asks for a “pro forma”, ask what they need it for: customs, finance, approval or payment. See quote vs estimate vs invoice.

Countries differ: what to check before you ship

Customs systems are not uniform. The summary below is not a substitute for local advice, but it lists the questions that matter in almost every country.

Question	Why it matters	Where to look
Is a commercial invoice required, and in what language?	Some destinations require a particular language or translation	Importing country’s customs website or your freight forwarder
Is a certificate of origin needed?	Preferential duty rates often depend on it	Chamber of commerce or trade authority
Are there import licences or restricted goods?	Missing licences stop the shipment	Customs authority, trade department
What duty and tax will the buyer pay?	Affects whether DAP or DDP is sensible	Tariff database for the importing country
Are there value thresholds for informal clearance?	Low-value consignments may follow simpler rules	Customs authority
Does the destination need a registration number?	Some require tax or importer IDs on the invoice	Buyer or broker

Ask your buyer, too. They often know exactly what their broker will want, and a short question before you ship saves days at the border.

The document set that travels with a shipment

The commercial invoice is rarely alone. Customs and carriers usually expect a small bundle of documents that agree with one another.

Document	What it does	Who usually prepares it
Commercial invoice	States the sale and value	Seller
Packing list	Lists cartons, contents, weights and dimensions	Seller
Bill of lading or air waybill	Contract of carriage and receipt for goods	Carrier
Certificate of origin	Confirms where goods were made	Chamber of commerce or authority
Insurance certificate	Evidence of cover, where required	Insurer
Export declaration	Records the export with customs	Exporter or agent
Import declaration	Records the import and duties	Importer or broker

The documents must agree. If the commercial invoice says 200 wallets and the packing list says 190, the shipment can be held while someone explains the difference. A two-minute cross-check before sending the bundle is worth far more than the time it takes.

Real-world situations

The same two documents behave differently in different situations. These short scenarios show how to choose and word them.

Situation	What to send	Key point
A new overseas buyer wants to pay before you ship	Pro forma with bank details and validity	Show the total, any fees and the date the offer ends
A bank needs paperwork for a letter of credit	Detailed pro forma with Incoterms and origin	Match the wording the bank asked for exactly
You send a replacement part under warranty	Pro forma marked “no charge, replacement”	Declare the real value for customs
A domestic customer wants an advance before custom work	Pro forma or a deposit invoice	Check local rules on advance invoices and tax
You ship goods to your own warehouse abroad	Pro forma or proforma-style invoice for transfer	Value and purpose must be consistent with your records
A trade fair exhibitor sends goods temporarily	Pro forma marked temporary export	Keep documents to prove the goods came back

If a recipient asks for a “pro forma” and is not clear why, ask one question: what will you do with it? The answer tells you whether they need a quote, an advance invoice, a customs document or just a price confirmation, and each has a slightly different form.

Records to keep

Keep the pro forma, the order confirmation, the commercial invoice, the packing list, the transport document and proof of payment together in one folder for each shipment. Customs authorities and tax offices can ask for them years later, and retention periods for trade documents are often longer than for ordinary invoices. Check the period in the countries involved, and keep digital copies that are easy to find. Naming files with the invoice number and the customer name, such as PF-0007_UmarImports.pdf, makes the archive far easier to use.

Which document does your buyer actually mean?

When a buyer asks for a “pro forma invoice”, they may mean any of four different things. Asking one short question saves a revised document.

What they say	What they probably need	What to send
“Send me a pro forma so I can pay”	A payment request before shipping	Pro forma with bank details, or an advance invoice if your tax rules require one
“Our bank needs a pro forma”	A document to support a transfer or a letter of credit	Detailed pro forma with Incoterms, origin and validity
“Customs asked for a pro forma”	A value declaration for goods that may not be sold	Pro forma or customs invoice stating the reason for shipment
“I need it for approval”	A document to raise a purchase order	Pro forma or quote with total and terms

A short email helps: “Thanks. To make sure the document works for you, could you tell me whether it is for payment, a bank, customs or internal approval?” The answer usually takes one line, and it tells you which details to include and which tax treatment to follow.

Frequently asked practical questions

Can I change the total after sending a pro forma?

Yes, but only by issuing a new version that clearly replaces the old one. If the buyer has already paid an advance against the earlier total, your revised document must show that payment so the balance is right.

Should the pro forma show tax?

Show it if tax will apply and the buyer needs the total. Mark it as estimated if the rate depends on the final shipment, and say whether it is included or excluded in the total. Never show a tax number you are not entitled to use.

What if the buyer never pays the advance?

A pro forma that is unpaid is simply an expired offer. Do not start production or ship until the agreed advance arrives, and let the validity date lapse. Keep a copy in your records with a note that it was not accepted.

Can the pro forma become the commercial invoice?

You can reuse the content, but not the number or the title. Issue the commercial invoice as a new document that matches what was actually shipped, and refer to the pro forma and any advance paid.

Mistakes to avoid

• Not marking the document clearly. An unlabelled pro forma may be treated as a final invoice, causing double payments or tax reporting issues.
• Using wrong values for customs. Declaring a lower value than the real price is a serious offence in many countries. Be accurate.
• Reusing the pro forma number for the invoice. Issue the commercial invoice with its own number and refer to the pro forma.
• Omitting terms of sale. State Incoterms and who pays freight and insurance.
• Ignoring the advance payment. When the final invoice is issued, show the advance as a credit.
• Letting the validity lapse. A pro forma with no expiry may be used months later at outdated prices.

A checklist before you issue either document

Check	Pro forma	Commercial
Correctly labelled in the title	Yes	Yes
Unique number, not reused	Yes	Yes
Date and validity or terms stated	Validity date	Date of issue
Seller and buyer details complete	Yes	Yes
Goods described specifically	Yes	Yes, matching the packing list
Quantities, prices and currency stated	Yes	Yes
Incoterms and named place	Yes	Yes
Freight and insurance shown separately	Estimated	Actual
Advance payments shown	Requested	Deducted
Reason for issue and origin	If relevant	Yes
Total checked	Yes	Yes

Currency, exchange rates and bank fees

International documents mix currencies more often than domestic ones, and the pro forma is the point at which to settle which one applies. Quote in one currency and state it plainly. If you quote in the buyer’s currency, say how long the price holds, because the exchange rate moves between the pro forma and the date the advance arrives.

Bank fees are another common source of short payments. International transfers can lose a share along the way to intermediary banks. Write on the document who bears them: “All bank charges are for the buyer’s account” or “Charges shared”. If your buyer uses a different currency from yours, name the currency of the payment and the amount you expect to receive, not only the amount they should send. For more on this topic, see invoicing international clients.

Frequently confused terms

Term	What it usually means
Proforma invoice	Same as pro forma invoice, spelled as one word
Commercial invoice	Final invoice for a sale, used by customs
Customs invoice	A specific customs form some countries require, often with a commercial invoice
Tax invoice	An invoice meeting local tax rules, used to claim or account for tax
Sample invoice	A pro forma-style document for no-charge samples
Advance invoice	An invoice issued before delivery for a deposit or prepayment, treated as a real invoice for tax
Sales order	The seller’s internal confirmation of an order
Packing list	A list of packages and contents with no prices

Two of these deserve a warning. An advance invoice is a real invoice in many tax systems, so it is not the same as a pro forma, even though the two can look alike. And a customs invoice is not always the same as a commercial invoice, so check what your destination requires.

International shipping tips

If you export, read invoicing international clients for currency, bank fee and tax points. For tax rules and customs forms, rely on the authorities in the exporting and importing countries or a freight forwarder, since requirements vary by destination and goods.
