What is a Proforma Invoice (PI)? Buyer & Seller Decision Guide

1. Issue PI after quotation acceptance.
2. Buyer checks Incoterms, MOQ, lead time, bank details.
3. Deposit / L/C per PI.
4. Produce → ship → issue commercial invoice matching shipped reality.

PI locks currency, price tiers, and deposit %. FX moves after expiry create renegotiation. Never pay against expired PI without revision.

Main risks: cash lock, document rejection, duty surprise, shipment delay, and relationship damage from unclear terms.

• Using PI as customs invoice
• Bank name ≠ legal seller
• PI ≠ later commercial invoice values without amendment
• No validity date
• Missing named Incoterms place

A Proforma Invoice (PI) states goods, prices, Incoterms, payment, and validity before shipment. Buyers use it to approve and pay deposit; banks may use it to open L/C. Customs clearance requires a commercial invoice for the actual shipment.

Keep definitions operational: name places/ports, dates, document triggers, and cash milestones — avoid naked acronyms in contracts.

Sales PI · Sample PI · Revised PI (versioned) · PI for L/C opening. Always version-control revisions.
