"Fee-based business model" means that its business model is centred around charging fees for its services (or products). Other ways to use "[noun]-based business model" could be: Ex: Its business model is service-based, which means that it makes money by selling services. Ex: My job is commission-based, so I don't get paid a regular salary every month.
