Time tracking software for freelancers logs billable hours per client and project, then turns that log into a timesheet or invoice. Clockify has the most generous free tier (up to 5 users, unlimited tracking), Toggl Track has the simplest one-click timer, and Harvest is the only one of the three with real invoicing built into its free plan. For a solo freelancer, the right pick depends on one question: do you want a separate tool just for tracking, or do you want tracking and billing in the same place.

"Time tracking software" turns up two very different kinds of tools when you search it: employee monitoring software built for a manager watching a team, and simple timers built for a freelancer tracking their own billable hours. This guide is only about the second kind.
For a freelancer, the job is narrow: start a timer or log hours against a specific client and project, keep an accurate record without much manual effort, and turn that record into something you can bill from. This guide covers the three tools that do that job well, what to look for before picking one, and where tracking time stops helping and invoicing software needs to take over.
What Time Tracking Software Actually Does for a Freelancer
Three things happen once you connect a time tracking tool to your work: a timer runs while you work a specific client's project (or you log the hours manually after the fact), the tool totals those hours into a timesheet you can review, and most tools let you attach an hourly rate so the timesheet doubles as a record of what you are owed.
That last part is the real value. A freelancer who does not track time reliably tends to underbill, not overbill. Interruptions, quick favors, and "I will just fix this real fast" work all disappear from memory by invoice day. A timer running in the background is the only reliable defense against that.
Key Terms You Need to Understand
Billable rate
The hourly rate attached to a client or project, so tracked time automatically calculates into money owed instead of just hours.
Timesheet
A summary view of hours logged over a period, usually grouped by client, project, or day, that you review before invoicing or exporting.
Idle detection
A feature that notices when your timer has been running with no keyboard or mouse activity and prompts you to discard or keep that idle time, so a forgotten timer does not quietly inflate an invoice.
Manual vs automatic entry
Manual entry means typing in hours after the fact from memory. Automatic entry means a running timer captures the real time as you work. Automatic is more accurate; manual is more forgiving if you forget to start the timer.
Project budgeting
Setting a cap on hours or cost for a project so the tool can warn you when tracked time is approaching or exceeding what was quoted.
Seat
One paid user license. Most of this category prices per seat per month, which matters even for a solo freelancer if you ever add a subcontractor or assistant.
What to Look For Before Choosing
Four questions to answer before picking a tool.
The 3 Tools Compared
| Tool | Free tier | Entry paid price |
|---|---|---|
| Clockify | Up to 5 users, unlimited tracking (1-month data history) | $3.99/seat/month (Basic, annual) |
| Toggl Track | Up to 5 users (1 admin), free forever | $9/month per license (Starter) |
| Harvest | 1 seat, 2 projects, invoicing included, free forever | $9/seat/month (Teams, annual) |
Pricing sourced live from each vendor's own pricing page. Check current pricing before budgeting, this category adjusts free-tier limits often.
Clockify: The Most Generous Free Tier
Clockify's free plan is built to be usable indefinitely rather than a trial disguised as a free tier: up to 5 users, unlimited time tracking, timer and timesheet views, calendar sync, and basic reporting, all at $0.
Best for
A freelancer who wants unlimited free tracking with no project cap, and does not need invoicing baked into the same tool. Clockify's dedicated freelancer feature set adds billable rates, project budgeting, and multi-currency support once you need them.
Not suited for
A freelancer who wants to invoice directly from the tool on the free plan. Invoicing on Clockify only unlocks at the Standard tier. The free plan's reporting is also limited to one month of historical data, a real constraint if you review quarterly.
Pricing
Free at $0. Basic at $3.99/seat/month annual adds unlimited history and admin controls. Standard at $5.49/seat/month annual adds invoicing and time-off tracking. Pro at $7.99/seat/month annual adds expense tracking and project budgeting. Monthly billing runs about 25% higher across every paid tier.
Toggl Track: The Simplest Timer
Toggl Track's whole design philosophy is friction removal: a one-click timer, a clean interface, and reporting that stays out of your way until you want it.
Best for
A freelancer who wants the fastest possible timer with the least visual clutter, and is comfortable using a separate tool for invoicing. The free plan genuinely has no expiration, and browser and calendar integrations cover most day-to-day workflows.
Not suited for
A freelancer who wants invoicing in the same tool. Toggl Track does not do billing at all, at any tier, by design, so you will always need a second tool for that step.
Pricing
Free forever for up to 5 users (1 admin seat). Starter at $9/month per license. Premium at $14/month per license for the first year, renewing at $18/month. Enterprise custom-priced.
Aziz's take: Most freelancers do not actually need Toggl over Clockify on features. They pick it because the timer feels good to use every single day, and a tool you enjoy opening is a tool you actually keep running. Do not underrate "which one will I actually use" as a real selection criterion here. The best time tracker is the one that is still running in your browser tab in month three.
Harvest: The Only One With Real Invoicing Built In
Harvest is the one tool in this guide that treats tracking and billing as a single job rather than two separate tools bolted together, and its free plan reflects that: invoicing, expense tracking, and the timer all ship together at $0.
Best for
A true solo freelancer with a small number of steady clients who wants tracked time to turn directly into a sent invoice without exporting to a second tool. The free plan requires no credit card and never expires.
Not suited for
A freelancer juggling 3 or more active clients on the free plan. The 2-project cap is the tightest limit of any tool in this guide, and you will hit the paywall on client count before you hit any tracking limit.
Pricing
Free forever: 1 seat, 2 projects, invoicing and expense tracking included. Teams at $9/seat/month annual ($11/seat/month billed monthly) removes the project cap. Enterprise and Enterprise Plus scale up with custom pricing.
If invoicing is the piece you actually need most and tracking is secondary, our best invoicing software for freelancers guide covers dedicated billing tools that go deeper than any tracker's built-in invoicing, including Harvest's.
What Time Tracking Software Cannot Do
These tools solve one specific problem well. A few adjacent problems still need something else.
What you still need elsewhere
A contract that defines what you are billing for
Accurate hours mean little if the client never agreed to your rate or scope in writing. Our free contract template for freelancers covers that agreement before the first timer ever starts.
Discipline to actually start and stop the timer
No tool fixes a habit problem. If you consistently forget to track, look for the tool with the fastest, most frictionless start action, and build starting the timer into the first thing you do when you open a client's work.
Your actual bookkeeping
A timesheet is not a set of books. Once invoices are sent and paid, that income still needs to be categorized and reconciled. Our bookkeeping software for freelancers guide and AI tools for accounting guide cover what happens after the invoice.
How to Get Started in Under 10 Minutes
The setup is nearly identical across all three tools.
Step 1
Set up one project per client, not per task
Client-level tracking is what actually maps to an invoice later. You can always add task-level detail inside a project, but client-level structure should exist from day one.
Step 2
Enter your billable rate per client
Do this once per client up front so every tracked hour already shows you what it is worth, instead of doing the math manually at invoice time.
Step 3
Install the browser extension or desktop app
A timer you have to open a separate tab for gets skipped. A timer that is one click away in your browser toolbar or menu bar gets used.
Step 4
Review your timesheet weekly, not just at invoice time
A weekly check catches a forgotten timer or a miscategorized entry while you can still remember what actually happened. Waiting until the end of the month means guessing.
Aziz's take: The honest reason most freelancers underbill is not laziness, it is that admin work like starting a timer feels like it can wait until later, and later never comes. Pick whichever tool has the lowest-friction timer for you specifically and treat starting it as part of opening the work, not a separate task you do afterward.
