Best Time-Tracking Tools for Freelancers Billing Multiple Hourly Rates (2026)

Harvest is built around the exact problem this guide addresses: turning billable hours charged at different rates into accurate, sent invoices. You can set a default hourly rate and then override it per project, per person, or per task, so a single client with a premium design rate and a discounted admin rate produces one invoice with each line billed correctly. Harvest applies the most specific rate automatically as time is logged, so there's no end-of-month reconciliation.

Where Harvest pulls ahead for freelancers is the track-to-invoice loop. Tracked billable time flows straight into an itemized invoice you can send with Stripe or PayPal payment links attached, and it syncs with QuickBooks and Xero if you keep books elsewhere. The Pro plan is a flat $10.80/user/month for unlimited projects, which is easy to justify the first time it saves you from under-billing a rush job.

The free plan (1 user, 2 projects) is enough to test the rate logic, but most multi-client freelancers will outgrow the 2-project cap quickly and want Pro.

Toggl Track is the most frictionless timer of the group, and its billable-rate system is flexible enough for almost any freelance rate card. On the Premium plan you can set billable rates at the workspace, project, project-member, and team-member levels, so different clients and projects each carry their own rate and totals roll up correctly in reports. If your main pain point is remembering to track at all, Toggl's one-click timer, idle detection, and background app tracking make consistent logging the easy path.

The trade-off is that Toggl Track focuses on tracking and reporting rather than invoicing. You get precise billable totals per project and per client, but you'll export those to a separate invoicing tool to actually bill. For freelancers who already invoice through an accounting app and just want bulletproof, flexible time data feeding it, that's often the ideal division of labor.

Rates require the Premium plan ($18/user/month); the Free and Starter tiers won't give you the full multi-level rate hierarchy.

Clockify offers the most granular rate control of any tool here, and a surprising amount of it is free. You can define billable rates in a hierarchy — workspace, then client/project, then team member, then task — and Clockify applies the most specific one to each entry. For a freelancer charging different rates by both project and type of work, that task-level rate is the feature that eliminates spreadsheet math, and even the paid tiers top out at just $9.99/user/month on Pro.

What makes Clockify stand out for cost-conscious freelancers is that custom billable rates are available on the free plan, alongside unlimited projects and tracking. You can run a genuinely multi-rate billing setup at zero cost, then upgrade only if you need labor/cost rates for profitability, invoicing, or approvals. It's the best value in the category by a wide margin.

The interface is dense compared with Toggl, and some polish (like the smoothest invoicing) sits on higher tiers, but for pure rate flexibility per dollar, nothing else comes close.

FreshBooks approaches the problem from the accounting side: it's a full freelance-business platform where time tracking is one feature feeding invoices, expenses, and books. You can assign different hourly rates per project or service, track time against them, and roll everything into a professional invoice — all without leaving the app. For freelancers who'd rather run one tool than stitch a tracker to a separate billing app, that consolidation is the whole point.

Because billing is FreshBooks' core competency, the track-to-invoice flow is especially strong: tracked hours at varied rates become itemized line items, and clients can pay online directly from the invoice. You also get expense tracking, automated late-payment reminders, and basic accounting, which a pure time tracker won't touch.

The catch is price and focus. Plans start at $23/month (Lite) and the time tracker itself is lighter than a dedicated tool like Toggl or Clockify — it's designed for billing accuracy, not deep productivity analytics. If invoicing and accounting matter as much as the timer, that trade is worth it.

Hubstaff earns its place through one capability many freelancers overlook until they subcontract: it separates bill rates from pay rates on the same tracked time. You can invoice a client at your bill rate while tracking what those hours actually cost you at a contractor's pay rate, which turns Hubstaff into a margin-and-profitability tool, not just a timer. Rates can be set per member and per project, so a small studio running work at several client rates gets accurate billing and cost data side by side.

Hubstaff also converts billable time into invoices and handles payments/payroll to contractors, closing the loop for freelancers who hand work off. Pricing starts low at $4.99/seat/month (annual), though note the two-seat minimum, which suits a freelancer-plus-subcontractor setup more than a strict solo operator.

Hubstaff leans toward workforce monitoring (screenshots, activity levels, GPS), which solo freelancers won't need and some may find heavy. If you don't subcontract, a simpler tool higher on this list is a better fit — but for tracking bill-vs-pay across a small team, Hubstaff is purpose-built.

Timely solves a different half of the multi-rate problem: making sure the hours you bill actually got captured. Its AI records your work automatically in the background — apps, documents, meetings, and web pages — and drafts time entries you approve, so billable hours at every client rate get logged even when you forget to start a timer. Once entries are in, you assign them to projects that each carry their own hourly rate, and Timely calculates billable totals per client accordingly.

For freelancers whose leakage problem is untracked time rather than rate math, that automatic capture is worth more than another rate field. You bill more accurately simply because fewer minutes slip through, and the private-by-default memory means only entries you approve ever leave your machine.

Timely is a tracking-and-reporting tool rather than an invoicing suite, so you'll export billable totals to bill. It's also pricier than Clockify or Toggl at $9–$22/user/month, and the AI-first approach is a philosophy shift if you like a manual stopwatch. But for capturing every billable minute across multiple rates, it's the standout.

Timeular is the wildcard: a tactile, habit-first tracker built around an eight-sided physical dice you flip to switch tasks, backed by a clean app. For freelancers who chronically forget to track, that physical cue can be the difference between billing real hours and guessing at month-end. Each activity or project can carry its own billable rate, so flipping to a different client's face starts logging time at that client's rate automatically.

The app also supports rate assignment per activity and generates billable summaries you can export, and it adds AI/calendar-based tracking suggestions on top of the physical device. For someone whose blocker is the habit of tracking rather than the sophistication of the rate engine, Timeular's approach genuinely changes behavior.

It's the most niche pick here: the tracker device is central to the experience, rate depth is simpler than Clockify or Harvest, and there's no built-in invoicing. Personal Pro starts at $9/month. Choose it if a tangible tracking habit matters more to you than a deep billing hierarchy.
