How to create an invoice

Before you start: what you need

• Your name and address (or company name and registered address)
• Your CVR number (Danish company registration number)
• Your bank account details (bank name, reg. no., account no., or IBAN/SWIFT for international clients)
• The client's name and address
• A description of what you delivered
• The agreed price

Step-by-step: creating a Danish invoice

1. Open the invoice builder. Go to pennapay.com/create — no account required. PennaPay's builder auto-generates the next sequential invoice number for you.
2. Fill in your details. Enter your name or company name, address, and CVR number. If you have a logo, upload it.
3. Add the client's details. Enter the client's name and address. For EU B2B clients where reverse charge applies, you will also need their EU VAT number.
4. Add line items. Describe what you delivered: e.g. "Website development — 10 hours × DKK 900". You can add as many lines as needed. Include a quantity and unit price for each.
5. Set the VAT type. Select Standard 25% VAT if you are VAT-registered. If not registered (under DKK 50,000/year), select "Private person". Other options include kunstnermoms (effective 5%), reverse charge (EU B2B services), and VAT-exempt (§ 13).
6. Set the due date. Danish invoices typically have a 14 or 30-day payment term. PennaPay defaults to 14 days — adjust as needed.
7. Add your bank details. Enter your bank account number so the client knows where to transfer the payment.
8. Preview and download. See the live invoice preview, then download as PDF. The PDF is ready to email to your client.

What makes an invoice legally valid in Denmark?

A full VAT invoice must contain: a unique sequential invoice number, invoice date, supply date (if different from invoice date), your name/address/CVR, the client's name/address, a description of the goods or services, quantity and unit price, the taxable amount, the VAT rate and VAT amount, and the total including VAT.

Invoice numbering

Danish law requires invoices to be numbered sequentially and without gaps (e.g. INV-001, INV-002…). You cannot retroactively renumber invoices. PennaPay assigns numbers automatically and keeps them sequential. If you issue invoice INV-005 and it needs to be cancelled, you issue a credit note — you do not delete or reuse the number.

Do you need a specialist template?

Some professions have specific billing needs. A photographer invoices for session fees, editing, and licensing; a musician bills for session work, beat licences, and studio time. PennaPay offers 33 free templates designed for specific freelance fields:
