Nutshell is a well-organized and collaborative CRM tool aimed at small businesses. Nutshell has powerful reporting and collaboration tools, integration with Exchange and Google Apps, comprehensive lead tracking tools, and more.
Although there is a web version of Nutshell, it’s also available as a standalone desktop app for Mac, PC, iOS and Android. However, if you’ve ever used the web version of Nutshell, you won’t notice much difference between it and the Mac app ,which basically plugs displays all the functions and features of the web app in a desktop shell. Still, it’s a worthy alternative to browser-based SaaS CRM apps, such as Salesforce, Insightly, or Pipedrive, if you want CRM functionality packaged within a desktop app.
