UK commercial invoice requirements

What the invoice needs to achieve

A commercial invoice should clearly identify the transaction and its amounts. For cross-border shipping, your intermediary may also need goods, origin, weight and delivery information that a basic sales invoice does not provide. There is no single checklist that resolves every destination and product.

Commercial detail vs customs detail

Separate three questions: does the invoice identify the sale, does the arithmetic reconcile, and is the information enough for this shipment? A document can pass the first two and still leave the customs agent asking questions. The pre-flight checker deliberately keeps those distinctions visible.

Fields to gather

• Invoice number and date; seller, buyer and final consignee where different.
• Related order, proforma or contract references and payment terms where relevant.
• Clear goods descriptions, quantities, unit values, line values and currency.
• Commodity codes, country of origin, net/gross weights and package marks or numbers where needed for the shipment.
• Agreed Incoterm with a precise named place, transport mode/route and any separately stated freight or insurance.
• Any declarations, certificates or destination-specific information that applies to the goods.

Build a usable invoice

Transcribe the invoice into the checker. Enter line quantities, unit values and line values exactly as shown. Use the goods total excluding separately stated freight and insurance. Review arithmetic results, then inspect every supplied field against the actual documents. Missing information may be inapplicable, but establish that rather than guessing.

Worked check

Typical gaps

• An unspecified currency symbol such as “$”.
• A generic description that cannot distinguish the goods.
• An invoice total that includes charges when the reviewer expects a goods-only total.
• Treating an origin country as the same thing as the despatch country.

Before dispatch

Confirm destination-specific document requirements, the meaning of each weight and any required declaration or certificate. READY in the tool means a specific arithmetic check passed; it does not mean customs compliance.
