Content Management System
If your site features a Content Management System (CMS) you would be able to add and edit content even if you are not familiar with HTML and without resorting to the services of a web designer. In this way you will be saving time and money.
CMS is of particular use if you need to regularly add new information or if you must perform frequent edits and updates (of prices and availability, for instance). If, on the other hand your site needs no frequent updates and is of a rather informative nature, then you may not need CMS yet!
