Within your settings dashboard, you find HELP buttons everywhere that give more information. We assume that you can find most of the answers here.
If it turns out to be more difficult, you can send us a support e-mail. getBIZZI aims to answer your questions within two working days. Often, we try and solve your issue the same day, because we know that your business is running on this. In practice, it means that if the answer cannot be found in the FAQ or in any other content, we will have personal contact about it.
