Yes, a proforma invoice is the document sellers typically use to request an advance payment, and buyers use it to authorize the transfer. It is a preliminary, non-binding statement of what the sale will cover, and it gives the buyer’s bank the details needed to send funds before production starts or goods ship. Using a proforma invoice for advance payment works well when the document is written tightly and both sides understand what it does and does not commit them to.
What the Proforma Must Contain to Trigger Payment
A proforma will only move money if it carries the information the buyer’s bank, customs broker, and accounting team all need. Every proforma should list the full legal names and registered addresses of the seller and buyer, a clear description of each line item with quantities and unit prices, and a total in the agreed currency.1International Trade Administration.

For advance payment specifically, several fields matter more than the rest:
- Payment terms stated explicitly. “100% advance payment required prior to production” or “30% deposit due upon acceptance, balance due before shipment” leaves no room for the buyer’s bank to hesitate. Vague wording is the most common reason a wire gets stuck.
- Complete banking details for the seller: bank name, account number, SWIFT code, and IBAN. Missing any of these forces back-and-forth email that delays the transfer.
- Shipping terms referenced by Incoterms rule, such as FOB or CIF. These define who pays for freight and insurance and where the risk of loss passes. They do not govern when ownership transfers; that belongs in a separate sales agreement.2International Trade Administration. Know Your Incoterms
- A validity period, typically 30 to 60 days, after which the quoted prices no longer apply.
- Harmonized System codes for each product on international shipments. Use the universal six-digit HS code; the country-specific ten-digit extensions vary and a mismatch can get customs paperwork rejected.
Label the document clearly as “Proforma Invoice.” The buyer’s accounting department needs to distinguish it from a commercial invoice, and customs authorities treat the two very differently.
How the Advance Payment Moves
Wire transfers are the standard method for international advance payments and the most secure from the seller’s side.3International Trade Administration. Cash-in-Advance Once both sides agree on the proforma, the buyer logs into their bank’s portal, enters the seller’s banking information, and uses the proforma invoice number as the payment reference. That reference is how the seller’s accounts receivable team matches incoming funds to the right order.
After the transfer is submitted, the bank assigns a tracking identifier (in the U.S. Fedwire system, a Federal Reference Number). Save that confirmation. It is proof the transfer was initiated and it is what either bank uses to trace the payment if it stalls.
International wire transfers typically cost around $45 for outgoing transfers, though fees vary by bank and rise for certain currencies or expedited processing. Funds generally arrive within one to five business days depending on the banks and currency involved.4Bank of America. How to Send Wire Transfers in Online Banking or Mobile App Intermediary banks along the route may deduct handling fees, so the seller sometimes receives slightly less than the invoiced amount. Ask your bank about the total cost chain upfront and send enough to cover any deductions if the seller expects the full figure.
Once the transfer clears, email the bank’s transaction receipt to the seller. That notification is what signals production or shipment preparation can begin.
Buyer Risk and How to Reduce It
Advance payment is the riskiest arrangement for the buyer. The money leaves your account before you receive anything, and if the seller fails to deliver, recovering funds across international borders is difficult and expensive. Sellers face almost no risk, which is why they prefer it.3International Trade Administration. Cash-in-Advance
That imbalance makes advance payment fraud persistent. Watch for sudden changes in the seller’s bank account details mid-transaction, invoices with only round-figure totals and no itemized breakdown, urgent payment demands that pressure you to skip verification, and any discrepancies between the proforma and earlier communications about specifications or pricing.
Several practical steps reduce exposure:
- Negotiate a partial advance rather than 100% upfront. A 30% deposit on acceptance with 70% due before shipment or upon inspection gives the seller enough commitment to begin work while limiting what you have at risk.
- Use an escrow service. A third party holds the funds until the seller meets agreed conditions such as shipping the goods, and if the goods fail inspection within a predetermined window, the funds return to you.3International Trade Administration. Cash-in-Advance
- Verify the seller independently before wiring a large sum to a new supplier. Confirm business registration, check references, and verify that the bank details match the registered business name. A phone call to the bank can sometimes confirm the account belongs to the company you think you are paying.
- Anchor the proforma in a separate purchase agreement covering delivery deadlines, quality standards, and refund terms. The proforma itself is non-binding, but referencing it in a signed contract makes obligations around the advance payment enforceable.
Sellers should also weigh the cost of insisting on full advance payment. Competitors willing to offer partial payments or letters of credit often win deals that rigid advance-only sellers lose.3International Trade Administration. Cash-in-Advance
Validity Periods and Price Protection
Because a proforma is not legally binding, the prices it quotes are estimates that can change before the commercial invoice is issued. A clear validity period, usually 30 to 60 days from the document date, protects both sides. Sellers in volatile industries sometimes use shorter windows. The document should state when the period begins, especially when hard copies travel by mail.
Sellers dealing with commodities or materials with sharp price swings sometimes include a price adjustment clause. This provision explains what happens if raw materials, freight rates, or tariffs change significantly between the proforma date and production. Common approaches tie the final price to a commodity index, cap adjustments at a stated percentage, or require the seller to issue a revised proforma if costs cross a threshold. Read these clauses carefully before wiring an advance payment, because loose wording can make the quoted price meaningless.
If a proforma expires before the buyer acts, the seller is under no obligation to honor the original terms. The buyer would need to request a new proforma, which may carry updated pricing.
What Replaces the Proforma Once Goods Ship
A proforma has a limited shelf life. Once goods are ready to ship, the seller issues a commercial invoice that replaces it for customs, accounting, and tax purposes. Customs authorities require the commercial invoice to clear goods across borders and to calculate duties and taxes on the actual shipment.5DHL.

The two documents rarely match line for line. The commercial invoice reflects final quantities (a run of 500 units might yield 498), the actual shipping date, confirmed freight costs, and any adjustments triggered by clauses in the original agreement. Where the proforma estimated, the commercial invoice locks in exact numbers.
The commercial invoice should reference the original proforma number so both parties and their banks can trace the transaction history. If the buyer paid the full amount in advance, the commercial invoice notes that payment was received and shows a zero balance due. If only a partial advance was paid, the remaining balance appears with its own payment terms.
How the Advance Payment Is Booked
A proforma is not a real invoice in the accounting sense and should not be recorded as an account payable. The buyer’s bookkeeper logs the advance payment as a prepaid asset on the balance sheet, not as an expense, until the goods arrive and the commercial invoice is issued. At that point the prepayment converts to a cost of goods or an expense in the normal course of accounting.
Tax authorities generally do not accept a proforma for sales tax or VAT reclamation. The commercial invoice is the document that supports any tax credit or deduction claim, and booking a proforma as a tax-deductible expense before the final invoice exists creates problems during an audit.
For U.S. sellers receiving advance payments, tax treatment depends on the accounting method. Accrual-method businesses generally must include the advance payment in gross income for the tax year it is received, with a limited one-year deferral election available under 26 U.S.C. ยง451 if the business also defers recognizing that revenue on its financial statements.6Office of the Law Revision Counsel. 26 USC 451 – General Rule for Taxable Year of Inclusion Cash-method businesses report the income when they receive the payment. The proforma itself does not create a tax event; the receipt of funds does.
