Vact Time Tracking Tools for Project Teams: Toggl, Harvest, and Clockify Compared
Time tracking in project management serves three purposes: billing clients accurately, understanding where team capacity goes, and improving estimation for future sprint planning. The right time tracking tool depends on whether you need client billing, project costing, or team productivity insights. The three most popular standalone time tracking tools — Toggl Track, Harvest, and Clockify — each excel in different areas.
Time Tracking Tools for Project Teams: Toggl, Harvest, and Clockify Compared
Why Track Time?
Client Billing
Agencies and consultancies that bill by the hour need accurate time records. Underbilling loses revenue; overbilling loses clients. Time tracking tools provide the data for accurate invoicing and the reports to justify charges.
Project Costing
Understanding how much time each project consumes helps organizations price future work, identify scope creep, and make investment decisions. If a project estimated at 200 hours is consuming 400 hours, that is a signal to investigate.
Estimation Improvement
Historical time data improves future agile estimation. If the team consistently underestimates backend API work by 30%, that insight informs better estimates for similar future work.
Capacity Planning
Time tracking data reveals how capacity is distributed across projects, activities, and team members. If developers spend 40% of their time in meetings, that constrains the capacity available for delivery.
Toggl Track
Toggl is the most popular standalone time tracker, known for its simple one-click timer and clean reporting.
Strengths: Intuitive UI, one-click timer, excellent reporting dashboards, Pomodoro timer, browser extensions, 100+ integrations including Jira and Asana. Timeline feature reconstructs your day from application and website activity.
Weaknesses: Invoicing is separate (Toggl Invoice). No native project management. Limited scheduling features.
Pricing: Free (5 users), $9/user/month (Starter), $18/user/month (Premium).
Harvest
Harvest combines time tracking with invoicing and expense tracking, making it the best choice for agencies that need billing capabilities alongside tracking.
Strengths: Built-in invoicing from time entries. Expense tracking. Capacity reporting. Integration with QuickBooks and Xero for accounting. Project budget tracking with alerts when approaching limits.
Weaknesses: Dated interface compared to Toggl. Fewer integrations. Reporting is less flexible.
Pricing: Free (1 user, 2 projects), $10.80/user/month (Pro).
Clockify
Clockify is the most generous free time tracker, offering unlimited users and unlimited tracking on the free plan.
Strengths: Free for unlimited users. Time-off tracking. Scheduling. Kiosk mode for team check-in/check-out. Project templates.
Weaknesses: Free plan has limited reporting and no invoicing. Paid plans are needed for advanced features. Interface is functional but less polished than Toggl.
Pricing: Free (unlimited users), $3.99/user/month (Basic), $5.49/user/month (Standard), $7.99/user/month (Pro).

Built-In Time Tracking in PM Tools
Many project management tools include time tracking, eliminating the need for a separate tool:
- ClickUp: Built-in time tracking on every task (free plan)
- Jira: Time logging on issues, with Tempo Timesheets for advanced tracking
- Monday.com: Time tracking column on Pro plan
- Asana: Through Harvest integration or third-party apps
- Linear: Time tracking on Plus plan
If your PM tool includes adequate time tracking, a standalone tool may be unnecessary overhead. If you need deeper reporting, invoicing, or cross-platform time aggregation, a dedicated tool is worth the investment.
Time Tracking Best Practices
Track in real time. Retrospective time entry (filling in time sheets at the end of the week) is inaccurate. Use timers to capture time as work happens.
Categorize consistently. Define project and activity categories before tracking starts. “Meetings,” “Development,” “Code Review,” “Planning,” and “Admin” provide useful breakdowns without excessive granularity.
Review weekly. Set aside 15 minutes each week to review time data and fill in any gaps. Stale data is worthless data.
Do not use time tracking for surveillance. Time tracking should help teams understand capacity and improve estimation, not monitor individual productivity. Teams that feel surveilled will game the system, producing data that is accurate but misleading. Use time data for process improvement, not performance management.
Choosing the Right Tool
For agencies that need billing: Harvest. For teams that prioritize reporting and insights: Toggl Track. For budget-conscious teams: Clockify. For teams already using a PM tool with built-in tracking: consider whether a separate tool adds enough value to justify the additional cost and context switching.
