Recommended OpusFlow places its focus on Outlook®-based solutions offering standard products and custom made solutions. OpusFlow CRM for Outlook takes the contact card as the starting point for linking and tracking of communication and which has been extended with a range of functionalities. Send personalized documents such as letters, faxes and e-mails from the Outlook address card. Track appointments, tasks and activities in relation to contacts. OpusFlow CRM can be used in conjunction with an Exchange server but it works without that as well. It is multi-user by design and needs only a network to use it as a groupware collaboration tool.
