Best Freelance Time Tracking Apps With Invoicing (2026)
The best freelance time tracking with invoicing comes from the tools that do both jobs in one place — capture your hours and turn them into a sendable invoice — without making you retype anything in between. The shortlist below covers the apps that genuinely cross both halves of that loop, and flags the ones that track time well but leave the billing to you.
Most "time tracker" reviews stop at how the hours get recorded. For a freelancer who bills by the hour, that's only half the story. The hours are worth nothing until they're on an invoice — so the real question is how cleanly a tool gets you from tracked time to money owed.
What to look for in a track-and-bill tool
Before the options, the criteria. These are what separate a tool you'll keep from one you'll abandon two invoices in:
- How time gets captured. Manual timers, activity-review tracking, or fully automatic. Anything that depends on you remembering to click start will leak hours — the question is how much.
- Billable vs. non-billable handling. You need to bill what's billable and exclude what isn't, ideally without sorting every entry by hand. See billable vs non-billable hours.
- Native invoicing, and on which plan. Some tools invoice on the free tier, some gate it behind a paid plan, and one popular tracker doesn't invoice at all. Read the plan, not the homepage.
- The handoff from hours to invoice. Does the billable total flow straight into a PDF, or do you export a CSV and rebuild the invoice elsewhere? This is where minutes — and accuracy — get lost.
- Platform coverage. If you're on Linux, your shortlist shrinks fast. Most native trackers ship Windows and macOS only.
- Pricing shape. Flat per-seat is predictable; usage-based extras can creep.

The options, compared
A few prices below are omitted because vendors change them often — details as of June 2026; check each vendor's site before you buy.
| Tool | Time capture | Invoicing | Linux | Trial / free |
|---|---|---|---|---|
| BillNotch | Fully automatic + AI categorization | Native PDF, all paid plans | Yes | 14-day trial |
| Harvest | Manual timer only | On the paid Teams plan | No | Free: 1 seat, 2 projects |
| Clockify | Review-based auto tracker | On the paid Standard plan+ | Yes | Permanent free tier (no invoicing) |
| Timely | Fully automatic AI tracking | Native, syncs with QuickBooks | No | 14-day trial |
| Toggl Track | Activity-review + manual timers | On paid plans | No | Free tier + 30-day trial |
| Rize | Fully automatic AI tracking | None | No | 7-day trial |
BillNotch
The pitch is the whole loop in one tool. The desktop app records your active window in the background — no timer to start — and AI categorization sorts that activity into client projects. The billable total it keeps feeds a native PDF invoice, with CSV export when your accountant wants the raw numbers. It runs on Windows, macOS, and Linux, and window titles can stay on your device if a project is sensitive. Pro is $9/mo, Team is $12/seat, with a 14-day trial. The piece most freelancers notice is the Revenue Leak Finder, which catches billable time that was tracked but never invoiced. More in BillNotch for freelancers.
Harvest
A long-standing, well-liked tracker with a clean invoicing flow once you're on the paid Teams plan. The tradeoff is the capture method: Harvest uses a manual timer, so the hours are only as complete as your discipline. Its free plan is genuinely free but tight — one seat and two projects — and some extras are usage-based, so read the plan carefully. No Linux build. If you live in a manual-timer habit and want straightforward billing, it's a solid pick; if forgotten timers are your problem, the capture side won't fix it. We go deeper in BillNotch vs Harvest.
Clockify
Generous where it counts: a permanently free tier that covers a lot of tracking. It offers a review-based "auto tracker" — it records activity for you to review, rather than auto-categorizing it into clients — and invoicing arrives on the paid Standard plan and up, not on the free tier. It's also one of the few here with a real Linux build. If budget is the constraint and you don't mind doing the categorization pass yourself, Clockify is hard to argue with.
Timely
Fully automatic AI tracking, with native invoicing that syncs with QuickBooks — a strong fit if QuickBooks is already your books. Pricing starts around $9/user/mo on annual billing and scales up with usage and features. It's Windows, macOS, web, and mobile — no Linux desktop. If you want automatic capture and live inside the QuickBooks ecosystem, it's a natural shortlist entry.
The honest caveats: Toggl and Rize
Two popular names need an asterisk for this specific use case.
Toggl Track is an excellent tracker, but it's built around activity-review tracking plus manual timers rather than fully passive capture, and invoicing lives on its paid plans. It's Windows and macOS only — no Linux. Great tool; just know invoicing isn't on the free tier.
Rize does fully automatic AI tracking very well — and has no invoicing at all. If your billing already lives somewhere else and you only want sharper focus and time data, Rize is a fine choice. As a track-and-bill tool, it's out of scope, because the "bill" half doesn't exist.
Picking from the shortlist
Match the tool to the failure you actually have. If you forget timers, prioritize automatic capture (BillNotch, Timely, Rize). If you want billing in the box without extra software, narrow to tools that invoice natively (BillNotch, Harvest on Teams, Clockify on Standard, Timely via QuickBooks). If you're on Linux, the field is short — BillNotch and Clockify are the realistic options. And if catching unbilled time matters as much as logging it, that's a specific feature to look for, not a given.
There's no universal winner here — only the best fit for how you work and what you're willing to do at invoice time. Whatever you choose, prices and plan boundaries move, so confirm the current details on each vendor's own pricing page before you commit.
