A billable hours tracker is software that records work time, applies an hourly rate, and turns those hours into a client invoice.
You can log hours for free almost anywhere, yet getting paid from those hours is harder. Rates, clean exports, and invoicing often sit behind a paywall that only appears after you commit.
Timen is the best free option for tracking billable hours in the United States, with unlimited users, projects, rates, exports, and built in invoicing at zero cost. Harvest Free suits solo freelancers with two clients. Clockify adds rates from 3.99 dollars monthly.
Key facts: Timen covers the full billing workflow at zero dollars. Clockify and Toggl cap free plans at 5 users. Harvest Free caps you at 2 active projects and 1 seat. PDF export is free everywhere, CSV export is often paid.
Free billable hours tools compared
The table below condenses each free plan to the five factors that decide billing. Rates and invoicing matter more than timer design when clients pay by the hour.
| Tool | Free users | Billable rates | Invoicing | Export | Report range |
|---|---|---|---|---|---|
| Timen | Unlimited | Included | Included | CSV and PDF | Unlimited |
| Clockify | Up to 5 | Paid only | Paid only | PDF only | 31 days |
| Harvest | 1 seat | Included | Included | Paid options | Unlimited |
| Toggl Track | Up to 5 | Paid only | Not native | PDF only | Unlimited |
One number to remember: Harvest Free stops at 2 active projects, while Timen allows unlimited projects and users at zero dollars. That single cap decides the choice for most growing freelancers.
What free actually covers in time tracking
Free plans always cover the timer itself. You can start and stop tracking, assign hours to projects, and view basic reports without paying anything.
Free rarely covers the full path from hours to money. Billable rates attach dollar values to time, and most free plans omit them. Without rates, the tool cannot calculate what a client owes.
Invoicing is the next divider. Timen and Harvest build invoices from tracked time at zero cost. Clockify requires a paid tier for invoicing, and Toggl has no native invoicing at any tier.
Exports decide whether you can bill elsewhere. PDF works for sending readable summaries to clients. CSV feeds spreadsheets and accounting tools, but Clockify and Toggl reserve CSV and Excel exports for paid plans.
The practical rule is simple. Stay free while rates, exports, and invoicing all work for your volume. Upgrade when a missing rate, a blocked export, or a project cap starts costing client time.
The honest traps: what they do not put on the pricing page
Free tracking is not free billing, and the gap only shows at invoice time. Read these traps before you commit, because each one has forced real freelancers to migrate mid project.
Free tracking alone is half a tool. Toggl and Clockify record unlimited hours at no cost, but rates and invoices need paid plans. If your workflow ends with a bill, the timer alone will not get you paid.
PDF export is not CSV export. A PDF is a readable document for clients, while CSV is structured data for spreadsheets and accounting. If you total hours in Excel, PDF only reports will force an upgrade sooner than expected.
Two projects is a hard ceiling. Harvest Free allows only 2 active projects and 1 seat. Freelancers with three or four clients must archive and restore projects constantly or pay for Teams at 9 dollars per seat monthly.
Five users is a hard ceiling. Clockify and Toggl cap free plans at 5 users. When a sixth person joins, the whole workspace must upgrade, with no option to pay for one extra seat alone.
Invoicing without delivery is half a workflow. Harvest Free builds invoices, but email sending and PDF export need Stripe connected for payments. Until that integration is set, the invoice stays trapped inside Harvest.
Timen: best if you want the full billing workflow free
Verdict: Best for freelancers and small teams that want unlimited tracking, rates, exports, and invoicing at zero cost.
Timen offers unlimited time tracking, projects, clients, and team members at zero dollars. Built in invoicing with status tracking is included, with no tiers and no per user pricing.
You get live timers, calendar views, detailed reports, and CSV plus PDF exports. Tracked time converts directly into invoices, so billing never needs a spreadsheet detour.
Considerations: Timen is maintained by the team behind Breeze, a paid project management tool. The tracker is standalone and fully featured, but integrations are fewer than Clockify or Toggl.
Skip if: You need deep integrations with Jira, Salesforce, or QuickBooks, or your agency requires profitability analysis, approvals, and audit logs for compliance.

Clockify: best if you want the cheapest paid billing upgrade
Verdict: Best for freelancers who want a fast free timer now and the lowest cost path to rates and invoicing later.

Considerations: Billable rates and CSV plus Excel exports start at Basic, priced at 3.99 dollars per user per month billed annually. Invoicing needs Standard at 5.49 dollars per user per month. Free reports cover 31 day ranges, and projects stay public unless you upgrade.

Harvest: best if you are solo with two clients
Verdict: Best for solo freelancers who manage two or fewer active clients and want polished invoicing without paying.
Harvest Free includes 1 seat, 2 active projects, time tracking, invoicing, and expense tracking at zero cost. Invoicing ships on every plan, so billing works immediately without an upgrade.
Invoices look professional with minimal setup, and tracked time turns into a clean bill. Expense tracking stays in the same place, so time and costs reconcile together.
Considerations: The free plan omits logo branding, invoice attachments, and QuickBooks Online integration. Paid Teams starts at 9 dollars per seat per month with unlimited projects and team reporting. You also cannot send invoices by email or export them as PDF without connecting Stripe.
Skip if: You manage more than two active projects, need a team, or want QuickBooks integration and branded invoices on the free plan.

Toggl Track: best if you want the simplest timer only

Considerations: Every money feature is paid only, with no billable rates, no native invoicing, and PDF only exports on the free plan. Starter at 9 dollars per user per month unlocks rates and structure, while Premium at 18 dollars adds approvals and profitability views.

Pick yours in five minutes
Match the tool to client count, billing needs, and export path. A short checklist beats a long trial.
- Count active clients and teammates, then remove any tool whose free caps you already exceed today.
- Decide whether you need rates inside the tracker or only need clean CSV exports for billing elsewhere.
- Check invoice delivery, including email sending, PDF export, and any Stripe connection requirement.
- Confirm report range and export format, especially if you bill annually or total hours in spreadsheets.
- Run one real client week in your top pick, from timer to invoice, before moving your full workload.
Tracked hours must become invoices and follow ups. Our invoice generator guide turns hours into bills, and our simple CRM guide keeps client follow ups alive.

If you want the complete billing workflow free, pick Timen. If you are solo with two or fewer clients, pick Harvest Free. If you want a fast free timer with the cheapest upgrade to rates, pick Clockify. If you only need the simplest timer and bill elsewhere, pick Toggl Track.
