What is a Letterhead Invoice?
The Letterhead Invoice is a fundamental business document used across Hong Kong's commercial landscape to request payment for goods or services while maintaining professional branding standards. It serves multiple purposes: as a formal payment request, a tax document for compliance with Hong Kong's Inland Revenue Ordinance, and a record-keeping tool for both issuer and recipient. This document type must include the company's business registration number as required by Hong Kong law, along with other mandatory elements such as invoice numbers, dates, and payment terms. A Letterhead Invoice differs from standard invoices by incorporating corporate branding elements and letterhead design, making it particularly suitable for professional services firms and businesses wanting to maintain brand consistency in their documentation. It can be issued both electronically and in hard copy, subject to the Electronic Transactions Ordinance of Hong Kong.

About the Letterhead Invoice
A Letterhead Invoice combines professional branding with legal compliance requirements under Hong Kong law. This document serves as both a formal payment request and a tax-compliant record that meets the stringent documentation standards required by Hong Kong's commercial legislation. Unlike standard invoices, letterhead versions incorporate your company's visual identity while ensuring full legal compliance with local ordinances.
When do you need this document?
You need a Letterhead Invoice whenever your business provides goods or services and requires payment while maintaining professional brand consistency. This is particularly important for professional services firms, consulting companies, and businesses that regularly interact with high-value clients who expect polished documentation. The document is essential when conducting business-to-business transactions, providing professional services like legal or accounting work, selling goods that require detailed documentation, or when your clients specifically request branded invoicing. Additionally, you must use compliant invoicing for tax purposes and audit trails as required by Hong Kong's Inland Revenue Department.
Key legal considerations
Your Letterhead Invoice must comply with multiple Hong Kong ordinances to be legally valid. The Business Registration Ordinance requires your business registration number to appear prominently on all commercial documents, including invoices. Under the Inland Revenue Ordinance, you must include specific tax information, maintain proper invoice numbering systems, and ensure accurate record-keeping for potential tax audits. The Trade Descriptions Ordinance mandates that all descriptions of goods or services must be accurate and not misleading. If you're issuing electronic invoices, compliance with the Electronic Transactions Ordinance is essential, particularly regarding digital signatures and electronic record validity. For goods sales, the Sales of Goods Ordinance governs the transaction documentation requirements, while service providers must consider the Supply of Services Ordinance implications.
Legal requirements in Hong Kong
Hong Kong law mandates several specific elements in your Letterhead Invoice. Your company information header must display your registered business name exactly as it appears in official records, complete business address, business registration number with the prefix "BR", and contact details including telephone and email. Invoice details must include a unique sequential invoice number, issue date, payment due date, and any relevant reference numbers for tracking purposes. Client information sections require accurate recipient details including full legal names and addresses. The itemization section must provide clear descriptions of goods or services, quantities, unit prices, and any applicable taxes or discounts. Payment terms must be clearly stated, including accepted payment methods and bank details if relevant. For tax compliance, you may need to include GST information if your business is registered for goods and services tax. All monetary amounts must be clearly stated in Hong Kong dollars unless otherwise agreed with the client.
