1 The initial costs for a small website with a few subpages can start from €500 to €1,000, depending on how much design templates have to be customized and whether there are other special features. The more complex a project is, e.g. in multisite environments or if further systems have to be connected to the website via interfaces, the higher the costs one has to reckon with. After the creation of a CMS website, however, there are further, partly running costs, which can vary individually depending on the service provider and system: Training, license, hosting, updates, care and maintenance are cost centers that your service provider should inform you about at the beginning and that you should otherwise actively ask about.
