Intervals review
A focused fit for service teams linking project work to budgets, billing, and time.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Intervals is web-based project management software for freelancers, agencies, consultants, developers, IT services companies, and other professional-services teams. It brings task management, time tracking, project budgets, reporting, document storage, client access, invoicing, and payment processing into one system. Work can be organized with table, card/Kanban, and simple task views, alongside calendars, milestones, sprint organization, and recurring tasks. Its strongest fit is a service firm that needs project delivery and financial tracking in the same workspace.
Pricing is paid and based on active projects rather than users. The Lite plan costs $29 per month and includes 3 users, time tracking, task management, project management, reports and analysis, and invoicing and payments. Basic costs $49 per month with unlimited users and the same listed core capabilities. Professional costs $99 per month, also with unlimited users and those capabilities. A 14-day free trial is available, and the pricing page advertises 20% savings with annual billing. The paid structure makes Intervals more relevant to firms that can connect its project, time, and billing functions to regular client work than to teams seeking a free entry tier.
Intervals also stands out for linking operational detail to service-business controls. Teams can compare project budgets with actuals, use general and task timers, schedule work with drag-and-drop rescheduling, maintain document version history, and provide client or executive access. Integrations include Claude, QuickBooks Online, Xero, FreshBooks, Slack, Google Drive, QuickBooks Desktop, and Basecamp Classic, while the REST API and data export support connected workflows. Choose Intervals when time, budgets, invoicing, and client visibility are central requirements. Teams wanting a free plan or broader platform coverage should look elsewhere.
