Proforma Invoice vs Invoice: Key Differences & When to Use Each
A Proforma Invoice is a preliminary bill showing what a sale will cost; an Invoice is the final demand for payment after goods or services are delivered.
People confuse them because both list prices and look official, yet only one triggers actual payment. Sales teams often send the Proforma version for approval, while accounting waits for the real Invoice to book revenue—timing that can feel identical to an outsider.
Key Differences
Proforma Invoice: issued before delivery, no accounting impact, negotiable. Invoice: issued after delivery, records revenue, legally enforceable. One forecasts; the other finalizes.
Which One Should You Choose?
Use Proforma when buyers need cost confirmation, customs clearance, or internal approvals. Switch to Invoice once goods ship or services render to trigger payment and update books.
Examples and Daily Life
An exporter emails a Proforma to a German buyer for import permits; once the container arrives, she mails the Invoice for bank transfer. A freelancer sends a Proforma for a website quote, then converts it to Invoice upon launch.
Can a Proforma Invoice become an Invoice?
Yes—update the date, reference, and status; most accounting apps let you convert in one click.
Is a Proforma legally binding?
No, it’s a good-faith estimate; only the final Invoice creates a debt.
Do I pay tax on a Proforma?
No taxes are due until the final Invoice is issued and recorded.
