🟢 Introduction
In global trade, documentation is everything. Among the essential papers, the Proforma Invoice and Commercial Invoice play a crucial role — yet many businesses confuse them. While they may look similar, their purpose, legal power, and timing differ significantly. This article explains the differences clearly, with real-world applications and practical tips for exporters and importers.
📄 What is a Proforma Invoice?
A Proforma Invoice is a preliminary bill of sale sent to buyers before shipment or production. It’s not a demand for payment but rather a quote or offer. It’s used for customs estimates, internal approvals, and starting import processes.
🔹 Key Features:
- Not legally binding
- Sent before goods are shipped
- Helps apply for import licenses or foreign exchange
- Includes estimated prices, shipping terms, and quantities
🧾 What is a Commercial Invoice?
A Commercial Invoice is a final, legally binding document used for customs clearance and payment collection. It confirms the actual transaction after the goods are shipped.
🔹 Key Features:
- Legally enforceable
- Used by customs for duty calculations
- Required for international payments and LC (Letter of Credit)
- Includes actual price, Incoterms, and shipment details
