A pro forma invoice looks similar to an invoice but is generally issued before the final transaction details are complete. Sellers use it to communicate expected products, quantities, prices, shipping, and terms so the buyer can approve, arrange financing, or prepare import steps.
It is not a substitute for the final commercial or tax invoice where those documents are required. Requirements and legal effects vary, particularly in international trade. Label the document clearly and obtain trade or tax advice for the jurisdictions involved.

When a pro forma invoice is useful
It can support a buyer’s internal approval, advance payment, bank or foreign-exchange process, import permit, or planning before shipment. It also provides a more invoice-like summary than a simple sales conversation.
The seller should use the best available information while showing what remains provisional. A validity date is helpful when prices, freight, exchange rates, or availability may change.
- Pre-shipment transaction summary
- Buyer approval or budgeting
- Advance-payment information
- Import and logistics planning
What to include
Common fields include seller and buyer details, a pro forma number and date, product or service descriptions, quantity, unit price, total, currency, estimated tax or charges, payment terms, delivery details, origin, and validity period.
For international goods, include shipment and classification information requested by the importer, freight forwarder, bank, or authority. Do not represent estimated values or codes as final when they remain subject to confirmation.
- Clear “Pro Forma Invoice” label
- Parties, items, quantities, and values
- Currency, terms, and validity
- Delivery and trade information
Pro forma invoice versus quote
Both can present a proposed price before a sale. A quote often functions as an offer for a defined scope, while a pro forma invoice presents transaction details in a format closer to the expected final invoice. Industry practice and document wording matter more than the title alone.
Use the document the buyer and process require. Avoid sending both without explaining their relationship. Reference the quote or sales order when a pro forma invoice follows it.
- Quote: proposed scope and price
- Pro forma: preliminary transaction statement
- Commercial invoice: final international sale document
- Final invoice: actual request and accounting record
Convert preliminary data carefully
When the transaction is completed, create the required final invoice using actual quantities, shipment, price, tax, and dates. Do not simply rename the preliminary PDF if details changed. Preserve both documents and connect them with references.
Confirm how advance payments are recorded and shown on the final invoice. Pocket Invoice creates standard custom PDF invoices; specialized pro forma or commercial workflows may require additional fields and review.
- Update every provisional field
- Use the final invoice numbering process
- Apply advances and credits visibly
- Retain linked transaction records
