High rate
The standard rate for most products and services: web design, advice, photography, business coaching.
Low rate
For example food and a number of services, such as the hairdresser or bike repair shop. Mixing rates? Choose 21% or 9% per line.
VAT reverse charge (EU)
Business customer in another EU country with a VAT number. You charge 0%, your customer accounts for the VAT in their own country.
On the invoice: "VAT reverse charged to the customer + customer VAT number"VAT reverse charge within the Netherlands
For example for subcontracting in construction. The main contractor accounts for the VAT.
On the invoice: "VAT reverse charged to the customer + customer VAT number"Small business scheme
Turnover under € 20,000 per year and registered for the KOR? Then you don't charge VAT. Set it once and it appears correctly on every invoice.
On the invoice: "Exempt from VAT under the KOR"Exempt services
Some services are outside the scope of VAT, for example in healthcare or education (article 11 Wet OB).
On the invoice: "Exempt from VAT under article 11 Wet OB"Customer outside the EU
Do you work for a customer in, for example, the US, the UK or Switzerland? Then your service is usually not taxed in the Netherlands.
On the invoice: "Service outside the EU: 0% VAT"Multiple rates on one invoice
Products at 9% and services at 21%? No problem: the VAT is added up separately per rate, just as it should be.
Not sure which scheme suits you? Check with your accountant or the Dutch Tax Administration. We make sure the invoice is correct for the choice you make.

Frequently asked questions
Is free really free?
Yes. You send one invoice per month without paying. It carries a small "made with Netslim" watermark. Drafts and customers are unlimited.
How do I pay for Pro?
By iDEAL or credit card the first time, then automatically per month or per year. You can cancel monthly at any time, right in your account.
Can I use it if my company is in Belgium?
No. In Belgium, VAT-registered companies have had to send invoices to other companies via Peppol since 1 January 2026, and a PDF by email is no longer enough. Use an accounting package with a Peppol connection instead. For companies in the Netherlands, everything works as usual.
Are my invoices tax compliant?
They contain everything the Dutch Tax Authority requires: a sequential number, date, your KvK and VAT number, the VAT per rate and, for EU customers, the note "VAT reverse charged". Make sure you enter your details correctly under Settings.
What does my customer see?
A neat email with your name as sender, the PDF as an attachment and a link to view the invoice online. If your customer replies, it lands in your inbox.
I'm in the KOR. Can I use this?
Yes. Under Settings, choose "KOR" as the default VAT scheme. No VAT is then added to your invoices, and the note "Exempt from VAT under the small business scheme (KOR)" is added automatically.
How do I create an invoice with reverse-charge VAT?
Under the lines, choose "Reverse charge: customer in another EU country" (or "within the Netherlands" for construction, for example). VAT goes to 0%, the text "VAT reverse-charged to the customer" is added, along with your customer's VAT number. If you don't have your customer's VAT number, we won't let you send a reverse-charge invoice to an EU customer, because the invoice would be incorrect.
Can I put 21% and 9% VAT on one invoice?
Yes. You choose the rate per line. At the bottom, the VAT is shown separately per rate, as the Dutch Tax Authority requires.
I work for a customer outside the EU. What now?
Choose "Export: customer outside the EU". You then charge 0% and the correct note is added to the invoice.
How long do I need to keep invoices?
The Dutch Tax Authority asks you to keep your records for 7 years. Your invoices stay in your account, and you can download every PDF for your own records or your accountant.
Your first invoice is ready in a minute.
