Instead of project-open

project-open alternatives

project-open brings project planning, staffing, tracking, collaboration and accounting together for service-industry work. Its portfolio tools coordinate projects, dependencies, approvals and capacity, while IT service management covers incidents, helpdesk, changes, configuration, software releases and SLAs. Professional services automation adds expenses, invoicing, payments, absence management and time tracking. A free Community Edition and Windows, Linux, Docker, VMware, self-hosted and SaaS deployment options give teams several ways to run it.

That breadth may be more than a team needs. Professional and Enterprise editions require at least 20 licenses and include two or six support requests per year; the free Windows installer is suited to five or six concurrent users. Alternatives range from groupware and CRM to Gantt planning and general project tools, with mobile platforms and different starting prices. When switching, weigh whether you need project-open’s service-management and PSA scope, how many people will use the product, and which platforms, hosting options and collaboration features matter most.
