What a pro forma invoice should include
Put “Pro Forma Invoice” at the top, assign a reference number, and give it an issue date and validity date. Then identify the seller, buyer, ship-to party and any buyer reference.
Describe each proposed item with quantity, unit, unit price and extended amount. For goods, include weights, dimensions, country of origin and commodity details when they are part of the proposed shipment. State the currency, discounts, freight or other agreed charges, payment terms, estimated ship date, delivery point and applicable Incoterm. Keep every amount visibly provisional until the transaction becomes final.
- Seller and buyer names and addresses, plus the buyer’s reference.
- Items quoted and their prices, including per-item prices and extended totals.
- Product weights and dimensions, where relevant to the proposed export order.
- Any applicable discounts.
- Terms of sale or Incoterm and the delivery point, along with the payment terms.
- Estimated shipping date and validity date for the quotation.
Scenario: requesting a prepayment or deposit
A seller may issue a pro forma before production or reservation of stock when the agreement requires money in advance. The document can show the proposed order total, the deposit or prepayment requested, the currency, the payment deadline and the remaining amount expected later. It should describe the trigger plainly: “30% prepayment to begin production” is more useful than a line that simply says “deposit.”
Once the seller receives the money, the payment belongs in the transaction record. The later final invoice can show the full delivered amount and credit the prepayment by date and reference. The pro forma itself does not become a receipt merely because it carried payment instructions; the receipt records money received, while the final invoice records the completed sale and remaining balance.
Scenario: giving the buyer details before a purchase order
Some buyers need a structured supplier document before their purchasing team can raise a purchase order. A pro forma can supply the proposed item descriptions, quantities, prices, freight, delivery date, supplier details and quote validity in a format that accounts payable can route internally.
Seller sends the pro forma; buyer reviews the proposed terms and creates a purchase order; seller accepts or resolves differences; goods or services are supplied; seller issues the final invoice with the purchase-order reference. The purchase order remains the buyer’s ordering document. The pro forma does not replace it, and the final invoice should reflect the transaction actually completed rather than copying obsolete proposed lines.
Scenario: arranging an export order
For a hypothetical export proposal, a U.S. seller offers a foreign buyer 100 units at $18 each. The pro forma identifies the product, unit count, quoted price, package count, gross and net weight, proposed Incoterm, payment terms, estimated ship date and the date the offer expires. The buyer can use that structured proposal while arranging an import licence, pre-shipment inspection, letter of credit or currency transfer.
Trade.gov says changes should not be made without the buyer’s consent. That makes revision control important. Keep the original reference, add a revision number or date, and state which earlier version the new document replaces. A changed quantity, ship date or delivery term can affect the buyer’s arrangements even when the grand total stays the same.
Scenario: supporting a letter of credit or currency transfer
A bank or buyer may use the pro forma to understand the proposed commercial terms before funds move. The names, addresses, currency, bank reference, goods description, amount and shipping terms should match the proposal the parties are discussing. Consistent spelling and reference numbers reduce avoidable mismatches between the pro forma, purchase order and later shipping documents.
When the transaction proceeds, the seller prepares the final commercial documents from the actual shipment and sale. That distinction matters when quantities change, a partial shipment leaves, freight is recalculated or the buyer accepts a substitution. The final invoice records what was sold; the pro forma records what was proposed.
Scenario: personal effects shipping
A carrier handling personal effects may ask for a pro forma-style inventory when there is no retail sale. The document can identify the sender and recipient, reason for shipment, package count, item descriptions, quantities, country of origin where known and a realistic declared value for each item. Use “personal effects — not for resale” only when that accurately describes the shipment.
Avoid a single line such as “used household goods.” A line-by-line inventory—used books, clothing, kitchen items and a personal laptop—gives the carrier a clearer record. A declared value is not a sales price and the document should not invent a buyer, purchase-order number or payment term when none exists. The carrier’s shipping documents remain separate from this descriptive inventory.
Scenario: samples, replacements and no-charge shipments
A shipment can have no customer charge and still need a useful description and declared value. Samples, warranty replacements and goods sent for demonstration can be listed with quantity, unit description, country of origin, reason for export and value used for the shipment record. Label the commercial reason accurately, such as “sample — no customer charge” or “warranty replacement.”
Do not force the extended amount to zero when the logistics record needs a declared value, and do not present that declared value as an amount payable. Separate columns—declared value and amount due—make the difference visible. If the transaction later becomes a sale, issue the final invoice for the actual sale rather than relabelling the no-charge pro forma.
How to convert a pro forma to a final invoice
Start from the accepted version of the proposal, then replace assumptions with actual transaction facts. Confirm the delivered items or services, quantities, unit prices, discounts, freight, currency, shipment date and payment already received. Give the final invoice its own invoice number and invoice date, while keeping the pro forma and purchase-order references for traceability.
Remove the “Pro Forma” label and any statement that the amount is provisional. Credit a deposit or prepayment as its own dated line. If only part of the proposed order was supplied, invoice the delivered part and leave the unsupplied balance out of that final invoice. If the price changed with the buyer’s consent, the final invoice should show the agreed final price rather than preserve superseded proposal math.
Keep both records. The pro forma documents the proposal used before the transaction; the final invoice documents the completed sale or billable delivery.
Worked handoff: from proposal to final invoice
Suppose PF-2026-014 proposes 40 display units at $25 each, $120 estimated freight and a $1,120 proposed total. The buyer agrees to a $336 prepayment and issues purchase order PO-804. The seller records that payment by date and reference but keeps the pro forma labelled as preliminary while production and shipping details are still open.
The completed shipment contains 36 units because four are deferred. Actual freight is $105. The final invoice therefore lists 36 × $25 = $900, adds $105 freight, credits the $336 prepayment and shows $669 due. It receives a new invoice number and date, cites PF-2026-014 and PO-804, and describes the four deferred units outside the billed lines. The seller retains the accepted pro forma and payment record with the final invoice so the change from proposal to completed sale remains visible.
This handoff keeps each document tied to its own event: the pro forma records the proposed 40-unit transaction, the payment record confirms the amount received, the purchase order records the buyer’s instruction, and the final invoice bills the 36 units actually shipped. A later shipment can receive its own invoice instead of reopening the completed one.
Pro forma invoice compared with nearby documents
Name the document for the stage of the transaction and keep its status visible.
| Document | Role in the transaction |
|---|---|
| Pro forma invoice | A quote in invoice format used as a negotiating tool before an export shipment. |
| Commercial invoice | Records the goods sold and amount payable after the transaction proceeds. |
| Quote | A price and scope proposal; it may be shorter and may not carry shipment-style fields. |
| Purchase order | The buyer’s document ordering the proposed goods or services. |
| Receipt | Confirms that money was received; it does not replace the proposal or final invoice. |
Numbering, validity and revisions
Use a reference series that cannot be confused with issued invoices, such as PF-2026-014. Add a validity date so the buyer knows how long the proposed price, exchange-rate basis, lead time and availability remain open. When a term changes, issue a dated revision and identify the version it replaces instead of overwriting the sent file.
A clean revision history might read PF-2026-014 Rev 2, replacing Rev 1 dated 4 May. Keep the buyer’s consent with the revised document. When the order becomes final, the resulting purchase order and final invoice can cite PF-2026-014 without reusing its number as the legal invoice number.
Common pro forma invoice mistakes
Put “Pro Forma Invoice” at the top and include a validity date. Do not add “Paid” unless a separate payment record supports it, and do not give the final invoice the same number.
Other failures are operational: vague item descriptions, no currency, no delivery point, totals that omit freight, a revision sent without marking the old version superseded, or a personal-effects inventory reduced to one generic line.
