Request for Proforma Invoice (RFI)

A Request for Proforma Invoice (often abbreviated as RFI) is a formal request made by a buyer to a seller asking for a provisional invoice before the actual sale is finalized. The proforma invoice serves as a quotation, outlines the terms of the transaction, and provides essential details such as product description, price, shipping, and payment terms. This document helps both parties confirm expectations, assess customs duties, arrange financing, and reduce misunderstandings.

Why a Proforma Invoice Is Important

Unlike a regular commercial invoice, a proforma invoice is not a demand for payment; rather it is a preliminary bill of sale. It is particularly useful in the following scenarios:

• International trade Customs authorities often require a proforma invoice to calculate import duties.
• Bank financing Buyers can present a proforma invoice to banks for letters of credit or trade finance.
• Price negotiation Sellers can clarify pricing, discounts, and incoterms before finalizing the deal.
• Project budgeting Clients can include provisional costs in project budgets and get internal approvals.

Key Elements of a Proforma Invoice

A wellstructured proforma invoice should contain the following information:

• Sellers details: Company name, address, contact person, phone, email, and tax identification number.
• Buyers details: Same set of information as the seller.
• Invoice number and date (often prefixed with PRO).
• Reference to purchase order or contract (if applicable).
• Description of goods or services: Quantity, unit of measure, unit price, and total amount.
• Incoterms (e.g., FOB, CIF, EXW) specifying who bears transportation costs and risk.
• Shipping details: Port of loading, destination port, expected shipment date.
• Payment terms: Advance payment, letter of credit, net30, etc.
• Validity period of the quotation.
• Bank details of the seller for payment (SWIFT/BIC, IBAN, account number).
• Any applicable taxes, duties, or fees that the buyer should anticipate.

Common Mistakes to Avoid

• Leaving out incoterms Without clear terms, both parties may assume different responsibilities for shipping costs and risk.
• Ambiguous product description Include model numbers, specifications, and any optional accessories.
• Missing validity period Prices can change quickly; always state how long the quotation remains valid.

• Use a distinct proforma invoice number (e.g., PRO202600123).

• Contract formation The proforma can become part of the contract if both parties accept its terms in writing.
• Record keeping Companies often store proformas for audit trails and tax documentation.
