The commercial invoice is the most important document in most export shipments. Customs authorities use it to assess duties and taxes, banks use it for payment, and the buyer uses it for their accounts. An accurate commercial invoice clears smoothly; an inaccurate one causes delays, extra costs, and sometimes penalties.
What a Commercial Invoice Must Include
Parties
- Seller / exporter: full legal name, address, and contact details
- Buyer: full name and address
- Consignee: if different from the buyer — the party receiving the goods
- Notify party: if applicable, often the buyer's customs broker
Invoice Details
- Invoice number and date
- Buyer's order or contract reference
- LC number, if paying by letter of credit
Goods Description
- A clear, specific description of each item — not "garments" but "men's 100% cotton knitted T-shirts, crew neck"
- HS code for each product line — see HS codes explained
- Quantity and unit of measure
- Unit price and total price per line
- Country of origin
Commercial Terms
- Incoterm and named place — for example "FOB Karachi"
- Currency
- Payment terms
- Total invoice value, with any freight, insurance, or discounts shown separately where relevant
Shipping Details
- Port or place of loading and destination
- Vessel or flight details if known
- Number of packages, marks and numbers, gross and net weight
Declaration and Signature
Many destinations or LCs require a signed declaration that the invoice is true and correct. Check with your buyer.
💡 Describe goods the way customs expects
Vague descriptions invite questions from customs officers. Include material, construction, and use — for example "stainless steel surgical scissors, reusable, non-sterile". Specific descriptions also support correct HS classification.
Commercial Invoice vs Proforma Invoice
A proforma invoice is issued before shipment to confirm terms and allow the buyer to pay or open an LC. A commercial invoice is issued at shipment and records the actual goods shipped. Quantities may change slightly between the two — the commercial invoice must reflect what was actually shipped.
Accurate Values Matter
Declared values affect duties at destination. Under-declaring values to reduce the buyer's duties is illegal, can lead to penalties for both parties, and may cause problems with your own export proceeds, which banks reconcile against the declared value. Always declare the true transaction value.
Common Mistakes
- Mismatched details: names, weights, or quantities different from the packing list or bill of lading
- Wrong or missing HS codes
- Vague descriptions that do not match the LC wording or that customs cannot classify
- Missing Incoterm or currency
- Wrong country of origin
- Undervaluation or overvaluation
- Spelling differences in company names across documents
Letters of Credit: Extra Care
Under an LC, the description of goods on the commercial invoice should correspond to the LC's description. Banks examine documents against the LC terms and international standard banking practice, so discrepancies can delay payment. Read the LC carefully before preparing the invoice. See letter of credit explained.
A Commercial Invoice Checklist
- Seller, buyer, and consignee names and addresses exactly right
- Invoice number, date, and order or LC reference
- Specific description for each line, matching the LC if applicable
- HS code, quantity, unit, unit price, and line total for each item
- Country of origin
- Incoterm and named place, currency, and payment terms
- Package count, marks, and weights consistent with the packing list
- Declarations, signatures, and stamps required by the buyer or LC
Keep Copies
Keep signed copies of every commercial invoice with the related packing list, Goods Declaration, and transport document. You will need them for tax records, bank reconciliation, and any claims or disputes.
