Independent Contractor Invoicing: How to bill clients.
Published {$created} by Tina Blum
As an independent contractor, invoicing is more than just sending a payment request — it’s a reflection of your professionalism and a crucial part of getting paid on time. Whether you're new to freelancing or looking to improve your billing process, mastering invoicing can help you maintain cash flow, build trust with clients, and reduce back-and-forth.
Why Professional Invoicing Matters
Clients expect clear and accurate invoices, sent on time. A confusing invoice can cause delays, or even non-payment. On the other hand, a professional invoice:
Sets clear expectations on when payment should be done
Builds trust in your services
Helps you stay compliant for tax purposes
Reduces misunderstandings
What to Include in an Invoice
Every contractor invoice should include the following:
Your name or business name and contact info - preferable phone number and/or e-mail address.
Client’s name and contact info, also CVR or VAT number.
Unique invoice number
Date of invoice and due date
Detailed list of services provided, including hours, rate, and totals
Subtotal, taxes (if applicable), and total amount due
Accepted payment methods (bank transfer, PayPal, etc.)
Payment terms (date) (e.g., “Due in 14 days”)
