Many Nigerian business owners use the terms "business invoice" and "commercial invoice" interchangeably — but they are not the same document. Using the wrong one, or including incorrect information on either, can lead to customs delays, payment disputes, or FIRS compliance issues.
This guide explains the difference, when each applies, and what each must include under Nigerian law.
What Is a Business Invoice?
A business invoice (also called a tax invoice or sales invoice) is a document issued by a seller to a buyer requesting payment for goods or services delivered within Nigeria. It is the standard invoice used for domestic commercial transactions.
Used for:
- Services rendered (consulting, design, legal, accounting)
- Goods sold within Nigeria
- Retainer and subscription billing
- Any domestic B2B or B2C transaction
Key requirements under FIRS guidelines:
- Seller's name, address, and TIN (if VAT-registered)
- Buyer's name and address
- Unique invoice number and date
- Itemised description of goods or services
- Amount in Naira (₦)
- VAT at 7.5% shown separately (if seller is VAT-registered)
- Payment terms and due date
What Is a Commercial Invoice?
A commercial invoice is a specific document used in international trade — for the import or export of goods. It is required by Nigerian Customs Service (NCS) and the destination country's customs authority to:
- Determine the customs value of the goods (for duty calculation)
- Verify the contents of the shipment
- Establish the legal transaction between the exporter and importer
Used for:
- Importing goods into Nigeria
- Exporting goods from Nigeria
- Cross-border trade with other African countries
- Air freight and sea freight shipments
A commercial invoice is not a request for domestic payment — it is a trade document that accompanies the physical shipment.
Side-by-Side Comparison
| | Business Invoice | Commercial Invoice | |---|---|---| | Purpose | Domestic payment request | International trade documentation | | Used for | Services and goods within Nigeria | Import and export shipments | | Currency | Nigerian Naira (₦) | Usually USD, EUR, or agreed currency | | Customs relevance | None | Required by Nigerian Customs | | VAT | 7.5% if seller is VAT-registered | Exports are zero-rated for VAT | | Shipping details | Not required | Required (Incoterms, port, weight) | | Country of origin | Not required | Required | | HS code | Not required | Required for each product |
What a Nigerian Commercial Invoice Must Include
If you are exporting goods from Nigeria or helping a client import, the commercial invoice must contain:
- Exporter details — full name, address, country
- Importer details — full name, address, country
- Invoice number and date
- Description of goods — specific, accurate, no abbreviations
- HS (Harmonised System) code — the international tariff code for each product
- Quantity and unit of measure — e.g., "500 units", "10 metric tonnes"
- Unit price and total value — in the agreed currency (usually USD)
- Country of origin — where the goods were manufactured
- Incoterms — e.g., FOB Lagos, CIF Apapa, EXW Kano (defines who bears shipping costs and risk)
- Port of loading and port of destination
- Gross weight and net weight
- Shipping marks and container/airway bill reference
Example commercial invoice line items for a Nigerian exporter:
| Description | HS Code | Qty | Unit Price (USD) | Total (USD) | |---|---|---|---|---| | Sesame seeds, raw, cleaned | 1207.40 | 20,000 kg | $0.85/kg | $17,000 | | Packaging (jute sacks) | 6305.10 | 400 units | $2.50 | $1,000 | | Total FOB Apapa | | | | $18,000 |
VAT on Commercial Invoices in Nigeria
Exports from Nigeria are zero-rated for VAT under the VAT Act. This means:
- Nigerian exporters charge 0% VAT on exported goods
- They can claim back input VAT on costs incurred producing those goods
- The commercial invoice should show VAT at 0% or state "Zero-rated export"
Imports into Nigeria attract import duty and VAT at 7.5% on the customs value — but this is paid by the importer to Nigerian Customs, not shown on the commercial invoice issued by the foreign exporter.
Common Mistakes on Nigerian Commercial Invoices
- Undervaluing goods — declaring a lower value to reduce customs duty. This is customs fraud and attracts serious penalties from the Nigerian Customs Service.
- Vague descriptions — writing "electronics" instead of specifying the exact product and HS code. This delays clearance.
- Wrong Incoterms — using CIF when FOB was agreed. This creates disputes about who pays insurance and freight.
- Missing country of origin — required for duty preference calculations under ECOWAS trade protocols.
- Currency mismatch — invoicing in Naira for an international shipment when the contract specifies USD.
When You Need Both Documents
If your Nigerian business sells goods locally and also exports:
- Use a business invoice for domestic customers (in Naira, with Nigerian VAT if applicable)
- Use a commercial invoice for export shipments (in agreed foreign currency, zero-rated for VAT)
They are separate documents for separate transactions — do not use the same template for both.
