Competitors and Competitor Categories
You can use StratNavApp.com to keep up to date with Competitors and Competitor Categories.
A competitor is an individual organisation, like ASDA or Tesco. A competitor category could be something like supermarkets or local restaurants. See also: How to link a Competitor to a Competitor Category.
Both Competitors and Competitor Categories have names and descriptions.
Competitors are a type of Organisation, whilst Competitor Categories are a type of Group. So for each of these two types of records, you can specify the type. Obviously, if you change these away from Competitor, or Competitor Category, then they become other types of Organisations or Groups.
