How to prevent rejection of your invoice on hiring external expertise

23 March 2023

We regularly see invoices that are not paid by the FSSC. The reason for rejection is the absence of an Assignment Agreement (Overeenkomst van Opdracht, or OVO).

On the Serviceplein platform a new button has been created called 'Inhuur zelfstandigen & derden'. 

We would like to ask you to consult this tile before looking at hiring external expertise. The application will also give advice if things can and should be done differently. 

If agreed then the app will make an OVO. This should be attached to the invoice so that it can be paid quickly and easily. 

Please take a look at it, as the app itself also contains a lot of relevant information.
