Clockify gives an IT service provider a full time tracker for less than any other tool in this list. The free plan covers up to 5 users with unlimited tracking, timers, timesheets, and a calendar view. The Basic plan at $3.99 adds time estimates, project templates, required fields, bulk editing, and the ability to add time for other people, plus invoicing on the Standard plan at $5.49.
Higher tiers add the pieces a growing provider needs. Standard brings timesheet approval, time off management, and recurring invoices, while Pro at $7.99 adds activity monitoring, scheduling, forecasting, expenses, labor costs, and profitability reports. Monitoring and forecasting sit behind the higher tiers, so price Pro, not Basic, for proof of work, and note that a team above 5 users cannot stay on the free plan.
