Duet is an intuitive software for managing self-hosted projects, invoices and collaborations. It eliminates time consumption thanks to a plethora of integrated tools that can be used by teams as well as customers, as per need. The software automates almost all of the tedious portions of a business and keeps work organised while providing instant visibility of project-wise statuses. Duet further enables fluid communication between the team members as well as among those from the authorities, besides ensuring that every bit of information uploaded stays private and that too, on a personal server. This keeps the data completely under the user’s eyes and further ensures that only those authorised to view can get access. Thus, customer lists and billing information are kept completely confidential to the user himself. A simple and interactive interface makes Duet a go-to for beginners. The installation process takes a maximum of ten minutes to be executed and is done by the wizard itself if the user gets stuck on any step.
