Key Elements of a Dutch Invoice
To ensure your Dutch invoice is compliant, it must include several mandatory details. Every invoice needs your company's full legal name and address, along with your customer's name and address. You must also clearly state your VAT identification number (BTW-id), which for sole proprietors typically starts with "NL" followed by 9 digits, the letter "B", and 2 digits (e.g., NL123456789B01). If you are registered with the Chamber of Commerce (KVK), your KVK number is also compulsory on all official documents, including invoices. Each invoice requires a unique, sequential invoice number and the invoice date. Additionally, specify the applicable VAT rate (e.g., 21% standard, 9% reduced, or 0% for certain transactions) and the corresponding VAT amount in euros for each rate. Don't forget to include a clear description of the goods or services supplied, including quantities or scope, and the date of supply if different from the invoice date.
