Your peace of mind starts here and now!

Fill in the form and let us collect your outstanding invoices.

How does it work?

Fill in the form. This should take about 10 min. (Tip: you will need to have your bank card and the outstanding invoice handy.)

As you fill it in, we will verify whether your case meets the legal conditions.

As a final step, you will need to pay an advance. But don't worry, this will be reimbursed with your payment!

Your work is done! Within a week, our bailiff will hand-deliver a payment reminder to your customer at home. If there is no response forthcoming, the bailiff will arrange a court order and the payment will thus be legally enforced.

After an average of 30 days, you will receive 100% of the money owed (plus reimbursement of your advance).

New legislation

In the past, when an invoice remained unpaid, the only option was to take it to court. Although this may have been simply a formality, it meant (costly) time wasted for you as well as the courts.

That is why the law was amended. For uncontested business-to-business invoices, a bailiff can now directly receive a judgement, without a lawsuit. In other words, the bailiff can almost immediately force your customer to pay.

Why Unpaid?


We'll dispatch a bailiff to your customer within the week. The bailiff will appear at the customer's home, which sends a strong message.


There is no travel involved for you. You simply fill in a single form on the website. We do the rest.

By experts.

This website is an initiative of experienced lawyers and bailiffs.


If successful, you will recover 100% (one hundred percent!) of the principal. In addition to reimbursement of your advance.

Also for small sums

Don't hesitate to submit a claim for small amounts too. After all, it's your money and you're entitled to it!

What clients say about us


I made a mistake on my invoice. Now what?
Your work is done! Your product has been delivered; your service has been carried out. You click on 'send', and off goes your invoice. That is always satisfying. But—oops—there appears to be an error on your invoice. And whoever notices this, you or your customer, you want to correct it as soon as possible. In this article, you will learn how to elegantly correct errors on invoices.
In which language should I draw up my invoices?
Suppose that I, as a Belgian company, have a non-Dutch-speaking customer. In which language should I draw up my invoice? At first sight, the answer may seem logical. To Dutch-speaking customers, you need to send an invoice in Dutch; to French-speaking customers, you need to send an invoice in French, and to other international customers, you need to send the English version. But, legally speaking, things work differently. We will explain it to you!
betwist niet zomaar een factuur
How quickly do you take the step of disputing an invoice with which you do not agree? As an entrepreneur certainly you should not let people walk all over you. But it is better not to dispute an invoice without thinking carefully, because such an action could cost you a lot of money. In this article, we explain how it works.
