Revolver Office offers a great number of essential features for managing different aspects of your business, like tools for communication with clients and suppliers, a business calendar, and different financial tools.
The program has two main sections, clearly identified on the interface: one for organizing tasks, and another for finances.
In the first you can manage emails with a specific client, organize your address book and calendar, set up reminders, and manage different professional projects.
The second section on the interface features the commercial side of your activity, where you can create lists of products and services, manage your sales and finances, and get reports, statements, and stats on business performance.
The Demo version has some limited features.
