Easy Proforma Invoice: Everything You Need to Know (2025 Guide)

 What is a Proforma Invoice?

A proforma invoice is a preliminary bill of sale sent to a buyer before a shipment or delivery of goods and services. It outlines the expected costs, terms, and conditions — but it’s not a legally binding invoice.

Think of it as a quotation with invoice formatting. It gives the customer clarity on what they’ll be paying, while allowing the seller to confirm pricing, shipping, and custom duties in advance.

📖 Definition: A proforma invoice is a formal document that declares the seller’s commitment to provide specified goods or services at a stated price. Read More 

🧠 Why Do Businesses Use Proforma Invoices?

• 💳 Help clients get internal purchase approvals

• 🧾 Maintain clarity before issuing the final commercial invoice

• 📦 Avoid disputes related to product, quantity, or price

In some industries, especially manufacturing, logistics, and B2B services, a proforma invoice is a standard part of the sales process.
