Online invoicing for Dutch freelancers: the complete 2026 guide

As a freelancer in the Netherlands, invoicing is one of the most important parts of your administration. Yet many freelancers spend unnecessary time manually creating invoices in Word or Excel. In this guide, you'll learn everything about online invoicing: from legal requirements to the best tools and how to get paid faster.

Legal requirements for invoices in the Netherlands

The Dutch Tax Authority (Belastingdienst) has clear requirements for invoices. As a freelancer, you're required to include specific information on every invoice. Missing details can lead to rejected invoices and potential fines.

• Your full name and address (as registered with KVK/Chamber of Commerce)
• Your KVK number (Chamber of Commerce registration)
• Your BTW-id (VAT identification number)
• A unique, sequential invoice number
• The invoice date
• Client's name and address
• A clear description of the delivered service or product
• The amount excluding VAT, the VAT rate, and the VAT amount
• The total amount including VAT

Why invoice online?

Online invoicing offers major advantages over manual methods. You save time, make fewer errors, and always have an overview of your outstanding invoices. Most invoicing tools automatically comply with legal requirements.

• Automatic invoice numbering — no more duplicate numbers
• VAT is calculated automatically
• Professional invoice layout in your own branding
• Send directly via email from the tool
• Overview of paid, outstanding, and overdue invoices
• Automatic payment reminders
• Export functionality for your accountant or tax return

Popular invoicing tools for Dutch freelancers

There are dozens of invoicing tools on the Dutch market. The most popular options are Moneybird, e-Boekhouden, and Exact Online. They range in price from free (limited) to about €20 per month for the most complete packages.

Moneybird is popular for its user-friendly interface and free starter plan. e-Boekhouden offers more accounting depth. Exact Online is more powerful but also more complex and expensive — better suited for growing businesses with employees.

When is standard software not enough?

Standard invoicing tools work fine for simple situations. But as your business grows, you'll notice limitations. Perhaps you want to integrate invoicing into a client portal, automatically generate invoices from projects, or let clients pay directly online via iDEAL.

Outgrowing standard invoicing software? A custom-built portal with integrated invoicing is the next step.
