Helpling does not have a minimum order and you can cancel your bookings anytime. There is no plan or cancellation fee. However, do keep in mind that the service provider is employed by you and a notice period of 1 month might be applicable according to Dutch law.
Foremost it is important to talk about the cancellation with your household professional and come to an agreement together. Helpling has to point out that Dutch law assumes that any jobs in and around the house are being done with a labour contract based on the Home Service Scheme. That means that you as a private household are the employer of the service professional after the booking request has been accepted by them. That also means that in general you can only end the bookings in mutual agreement of with a good reason. Generally, a notice period will also be applicable when ending the labour agreement.
