Time Tracking Software Buying Guide: How to Choose the Right Tool for Your Team
Most time tracking software buying decisions go wrong in the same way: the buyer focuses on the feature list instead of the workflow. A tool with 50 features that your team won’t use is worse than a tool with 10 features they use every day.
This guide walks through the decision by team type, then gives you a framework for evaluating the shortlist.
Start with your primary use case
Time tracking serves different masters depending on who’s asking:
Billing accuracy — “Did I track all the time I need to invoice?” This is the freelancer and agency use case. The tool must make billing rates, billable/non-billable classification, and invoice generation easy.
Project profitability — “Is this project making money?” The agency and consulting firm use case. Requires budget tracking, billing rates, and ideally cost rates to calculate margin.
Payroll and HR compliance — “Are we recording hours correctly for legal compliance?” The employer use case. Requires start/end time capture, daily records, long-term data retention, and sometimes overtime calculation.
Personal productivity — “Where is my time going?” The individual knowledge worker use case. Can be served by personal tools (RescueTime) that wouldn’t work for billing.
Team accountability — “Is remote work happening?” The employer monitoring use case. Requires activity monitoring, screenshots, or GPS tracking.
Most teams have one primary use case and one secondary. The primary use case should drive the decision.
By team size and type
Solo freelancer
Needs: Billable/non-billable tagging, client-project structure, basic invoice generation or easy export.
Recommended: Toggl Track free (up to 5 users). Everything you need at zero cost. Upgrade to Toggl Starter ($9/user/mo) when you need billing rates and better reports.
Skip: Hubstaff (monitoring features you won’t use), Timely (AI capture is valuable for forgetful time-trackers but expensive for one person), Harvest (good but $12/mo vs free for identical features at solo scale).
Agency 5–20 people
Primary need: Project profitability, client reports, budget alerts.
Recommended: Harvest ($12/user/mo). Budget alerts, project profitability reports, native invoice creation, and shared client report links are the decisive features. The best billing-focused tool at this scale.
Alternative: If your team won’t adopt manual tracking (compliance below 70% after 3 months), Timely (£11/user/mo) solves adoption through automatic capture.
Skip: RescueTime (personal productivity, not billing), Jira time tracking (work log only, not billing).
Remote team 10–100 people
Primary need: Consistent time records across time zones, manager visibility without surveillance.
Recommended: Clockify ($4.99/user/mo Pro) for cost-conscious teams. Toggl Track ($18/user/mo Premium) for teams that need detailed reporting and billing rate configuration.
Skip: Hubstaff unless monitoring is an explicit business requirement — adding screenshot capture to a trust-based remote culture creates more damage than value.
Construction, field service, and non-desk workers
Primary need: GPS clock-in/out, job site tracking, overtime calculation, payroll integration.
Recommended: Hubstaff ($7/user/mo) — GPS tracking and geofencing clock-in are built-in. ClockShark (not reviewed here) is purpose-built for construction.
Skip: Toggl Track, Clockify — both designed for desk-based knowledge workers.
The feature decision framework
Must-have vs nice-to-have
| Feature | Must-have for | Nice-to-have for |
|---|---|---|
| Billable/non-billable tagging | Agencies, freelancers | Remote teams |
| Billing rate configuration | Anyone billing by the hour | Internal teams |
| Budget alerts | Fixed-price projects | T&M projects |
| Invoice generation | Freelancers, small agencies | Teams with separate invoicing |
| Client report sharing | Client-facing agencies | Internal teams |
| Automatic time capture | Forgetful teams | Everyone |
| GPS tracking | Field workers, construction | Office/remote teams |
| Screenshot monitoring | Explicit monitoring requirement | Generally not needed |
| Payroll integration | Employer hourly workers | Project-based billing |
| Project profitability | Agencies, consultancies | Internal teams |
The adoption test
The best time tracking tool is the one your team actually uses. Before committing:
- Run a 2-week trial with at least 3 team members
- Track compliance rate (what % of daily time is logged each day)
- Target: 85%+ compliance by week 2
- If below 75% by week 3 with manual tools, switch to automatic (Timely)
Compliance below 70% means your data is not reliable enough to bill from or make decisions on. A tool with more features that produces incomplete data is worse than a simpler tool used consistently.
Pricing realities
| Tool | Free tier | Paid from | What you gain at paid |
|---|---|---|---|
| Toggl Track | Up to 5 users | $9/user/mo | Billing rates, better reports |
| Clockify | Unlimited users | $4.99/user/mo | Projects dashboard, Scheduled reports |
| Harvest | No | $12/user/mo | Full billing, invoices, budget alerts |
| Hubstaff | No | $7/user/mo | GPS, screenshots, payroll |
| Timely | No (trial only) | £11/user/mo | Automatic capture, AI categorisation |
| RescueTime | Limited | $6.50/user/mo | All productivity reports, focus blocks |
The free tier trap: Clockify’s free tier is genuinely functional for most teams. Toggl Track’s free tier covers the basics up to 5 users. Both are worth starting with before deciding whether paid features justify the cost.
The per-user cost problem: At 20+ users, per-user pricing becomes significant. A team of 25 on Timely at £11/user/mo = £275/mo = £3,300/yr. Clockify at $4.99/user/mo = $1,497/yr. The 2.2x cost difference matters — confirm what you actually need from Timely’s automatic capture before committing at that scale.
Three questions before you buy
1. Will your team actually use it? The best tool your team won’t use is worse than the adequate tool they will. Evaluate adoption friction before feature sets.
2. Does it connect to your invoicing system? Harvest has native invoicing. Toggl Track and Clockify integrate with FreshBooks, QuickBooks, and Xero. If you already have an invoicing system, check the integration exists before buying.
3. What happens to the data in year 2? Time tracking data is valuable for pricing, estimation calibration, and capacity planning. Check how long the tool retains data, whether you can export it, and whether the price increases significantly on renewal.
