Letterhead Invoice Template for Indonesia

A letterhead invoice is an essential business document that combines your company's professional branding with legally compliant payment requests under Indonesian law. This document serves multiple critical functions: requesting payment from clients, providing tax-compliant documentation for VAT purposes, and creating an official record of your business transactions that meets regulatory standards set by the Directorate General of Taxes (DJP).

When do you need this document?

You need a letterhead invoice whenever you provide goods or services to clients and require formal payment documentation. This includes selling products to retailers, providing professional services to corporate clients, delivering consulting work to businesses, or completing project-based work for customers. The document is particularly crucial when dealing with VAT-registered businesses, as they require proper tax invoices for their input tax credits. You'll also need this document for international transactions where foreign clients require detailed invoicing for their accounting records and customs procedures.

Key legal considerations

Your letterhead invoice must include several mandatory elements to ensure legal compliance and enforceability. The company header must display your complete business name, registered address, contact information, and most importantly, your NPWP (Nomor Pokok Wajib Pajak) tax identification number. The invoice details section requires a unique invoice number, issue date, and payment due date to establish clear payment terms. Client information must be complete and accurate, including their NPWP if they are VAT-registered. Item descriptions must be detailed and specific, with clear quantities, unit prices, and accurate calculations. The total amount section must show subtotals, VAT at the current 11% rate where applicable, and the final amount in both numerical and written form to prevent disputes.

Legal requirements in Indonesia

Indonesian law imposes specific requirements on business invoices through multiple regulations. Law No. 42 of 2009 on Value Added Tax mandates that tax invoices include specific content and formatting to be valid for VAT purposes. The Indonesian Civil Code establishes basic requirements for commercial documents to be legally binding and enforceable. Law No. 7 of 2014 on Trade sets standards for business documentation and trade practices. If you're issuing electronic invoices, Government Regulation No. 82 of 2012 on electronic transactions applies. Minister of Finance Regulation No. 151/PMK.03/2013 provides detailed specifications for tax invoice formats and content. Your invoice must be issued within 30 days of goods delivery or service completion, and you must maintain copies for at least 30 years for tax audit purposes. Non-compliance can result in penalties ranging from administrative fines to rejection of VAT input credits.
