Running a software development agency means juggling multiple client projects simultaneously — and billing correctly is as important as shipping quality code. Across the 50+ projects we've delivered at Warung Digital Teknologi, I've watched time tracking go from a glorified spreadsheet habit to a genuine operational requirement. When you're working on a Photography Studio Manager, a Hotel Management Suite, and a Smart POS system all in the same week, knowing exactly where each billable hour went is not optional.
I've personally tested Toggl Track, Clockify, and Harvest in real client work environments — integrating them into Laravel-heavy project workflows, Flutter mobile projects, and multi-developer handoffs. Here's what I actually found.
Why Time Tracking Is a Different Problem for Dev Agencies
Generic time tracking advice is written for freelancers billing by the hour on one project at a time. Dev agencies have a different reality: multiple concurrent projects, mixed billing models (fixed fee vs retainer vs T&M), multiple developers logging time across shared Laravel/Vue codebases, and clients who want detailed reports at month end.
The three tools in this comparison each solve this differently. Toggl prioritizes simplicity and reporting. Clockify optimizes for team scale and cost. Harvest focuses on the billing-to-invoice pipeline. Let's break each one down.
Toggl Track — The Premium Simplicity Option
What It Is
Toggl Track is one of the oldest dedicated time trackers in the market, and it shows — in a good way. The product has refined its UX over years to the point where starting a timer takes one click and categorizing it takes one more. Their browser extension integrates with GitHub, Jira, Notion, Asana, and dozens of other tools, so developers can trigger timers directly from the task they're working in.
Features That Matter for Dev Teams
- Project and client segmentation — clean hierarchy of Workspaces → Clients → Projects → Tasks, which maps well to agency structure
- Team dashboard — see who is working on what in real time, useful for distributed teams
- Detailed reporting — exportable reports with breakdowns by project, team member, date range, and billable vs non-billable hours
- Idle detection — prompts developers who forgot to stop the timer after stepping away (a real problem in deep work sessions)
- Required fields — force team members to always attach a project and task before logging time, which prevents sloppy un-categorized entries
- Integrations — 100+ integrations including GitHub, GitLab, VS Code, Jira, Trello, Linear
Pricing
- Free: Up to 5 users, basic tracking and reporting
- Starter: $10/user/month — billable rates, time rounding, templates
- Premium: $20/user/month — forecasting, saved reports, priority support
- Enterprise: Custom pricing for large teams
What I Like
The VS Code extension is genuinely useful when you're switching context every hour across Laravel API work, Vue frontend, and Flutter mobile. I used Toggl on our Digital Pawnshop project — a complex multi-module system — and the ability to set up sub-tasks per module (authentication module, transaction engine, reporting dashboard) gave the client a clean breakdown at billing time without me having to reconstruct anything from memory.
Toggl's reporting is the most polished of the three. If you're presenting time breakdowns to enterprise clients who want professional PDF reports, Toggl's output looks the part.
What I Don't Like
The free plan's 5-user limit is a dealbreaker for growing agencies. And the jump from free to Starter at $10/user/month starts adding up fast — a 6-person team costs $720/year just for basic billable rate tracking. For budget-conscious agencies, that's real money.
Clockify — The Scale-Friendly Option
What It Is
Clockify takes the opposite pricing philosophy from Toggl: the core time tracking is completely free for unlimited users. They monetize with advanced features like GPS tracking, kiosk mode, and advanced reporting behind paid tiers. For agencies that want to onboard an entire team without a per-seat pricing discussion with management, Clockify is genuinely compelling.
Features That Matter for Dev Teams
- Unlimited users on free plan — no artificial cap forcing paid upgrades
- Timesheet view — weekly grid view that many developers prefer over a running timer approach
- Project budgets — set hour/cost budgets per project with alerts when approaching limits
- Approval workflow — team members submit timesheets, managers approve before invoicing
- Custom reports — exportable in CSV, Excel, PDF; filterable by any dimension
- API — full REST API for integrations with custom Laravel backend systems
- Kiosk mode — useful if you have on-site client office workers who clock in/out
Pricing
- Free: Unlimited users, unlimited projects, basic tracking
- Basic: $3.99/user/month — project templates, time rounding
- Standard: $5.49/user/month — invoicing, targets, reminders
- Pro: $7.99/user/month — GPS tracking, budgets, forecasting
- Enterprise: $11.99/user/month — custom subdomain, SSO
What I Like
Testing Clockify on our internal stack (Laravel + Vue) revealed something I hadn't expected: the API is well-documented and genuinely easy to integrate. For our E-Commerce Marketplace project, I wired up Clockify's REST API to auto-create time entries when developers pushed commits to specific feature branches — a neat trick that removed manual logging overhead for routine tasks. The webhook support made this straightforward from the Laravel side.
The free tier is genuinely functional, not crippled. A 10-person dev team can run Clockify free for months while evaluating whether the paid features (invoicing, GPS) are worth the upgrade. That risk-free period is rare in this category.
What I Don't Like
Clockify's UI is a step below Toggl in polish. Reports look more utilitarian, and the mobile app experience is less refined. If you're showing time reports directly to enterprise clients in a meeting, Toggl will impress more. Clockify also has a GPS/screenshot monitoring feature that some team members find intrusive — worth being transparent about if you enable it.
Harvest — The Invoicing-First Option
What It Is
Harvest's core differentiator is tight integration between time tracking and invoicing. While Toggl and Clockify require third-party tools (or custom code) to turn tracked hours into client invoices, Harvest does it natively. You track time, hit "Create Invoice," and it pulls billable hours directly — already totaled, already broken down by project. For agencies that bill T&M (time and materials) and need to invoice monthly, this workflow is genuinely faster.
Features That Matter for Dev Teams
- One-click invoicing from tracked hours — the killer feature; generates professional invoices automatically
- Expense tracking — log project expenses alongside time, included in invoicing
- QuickBooks + Xero integration — invoices flow directly into accounting software without re-entry
- Stripe and PayPal payments — clients can pay invoices online without leaving the email
- Project forecasting (via Harvest Forecast add-on) — capacity planning for upcoming projects
- Budget tracking — alerts when projects hit % of budget
- Slack integration — log time from Slack commands without switching apps
Pricing
- Free: 1 user, 2 projects only
- Pro: $12/user/month (billed annually) — unlimited users, projects, invoicing
What I Like
The invoicing workflow is genuinely 10x faster than exporting CSV from Clockify and manually building an invoice in Google Docs. When I integrated Harvest into the Hotel Management Suite project billing cycle, the time-to-invoice dropped from roughly 90 minutes of spreadsheet work to about 8 minutes. The client got a professional invoice with hour breakdowns by module, and it synced automatically with their Xero accounting setup.
For agencies where the developer is also the account manager and the invoicer (common in small shops), Harvest removes friction that genuinely costs hours per month.
What I Don't Like
Harvest's free plan (1 user, 2 projects) is essentially a trial, not a real free tier. The Pro plan at $12/user/month is the most expensive per-seat option in this comparison. And Harvest's developer ecosystem is thinner — fewer native integrations with dev tools like GitHub and Linear, compared to Toggl. It's optimized for billing operations, not developer workflow tooling.

Which Tool Fits Your Situation
Choose Toggl Track if:
- You have ≤5 developers and can stay on the free plan
- You present time reports directly to clients in meetings and need polished output
- Your team is deep in GitHub/GitLab/Jira workflows and wants native timer triggers
- You use a separate invoicing tool (FreshBooks, Wave, or custom billing system)
Choose Clockify if:
- Your team is 6+ people and per-seat pricing is a real constraint
- You want REST API access to build custom integrations (Laravel middleware, commit-based logging)
- You're running multiple projects simultaneously and need approval workflows
- You want to evaluate without financial commitment first
Choose Harvest if:
- You bill clients on T&M and invoice monthly — the invoicing workflow pays for itself quickly
- Your bookkeeper already uses QuickBooks or Xero and you need the sync to be automatic
- You want to let clients pay invoices online with minimal back-and-forth
- You're a solo dev or small agency where the developer handles billing directly
My Verdict After 11+ Years in Client Project Work
The tradeoff I've seen in production is clear: Clockify wins on economics, Toggl wins on developer experience, and Harvest wins on billing operations. These aren't close calls — each tool has a distinct lane.
For most independent dev agencies operating 5-15 person teams on mixed fixed-fee and T&M engagements, I'd recommend Clockify at the Standard tier ($5.49/user/month). The unlimited user model removes the "we can't add the junior dev to the system" friction. The REST API means you can build Laravel integrations that log time automatically for routine tasks. And the approval workflow is solid for ensuring timesheets are accurate before invoices go out.
If you're primarily T&M and invoicing directly, move to Harvest — the time you save each billing cycle at $12/user/month is worth it faster than the pricing suggests. And if your team is small (under 5) and client presentation matters, Toggl's reporting quality justifies the cost.
Don't bother running all three in parallel — the context-switching cost of deciding which tool to log in defeats the purpose. Pick one, enforce it as the standard across all projects, and integrate it into your project kickoff checklist.
Frequently Asked Questions
Can I use Clockify free forever for my dev team?
Yes — Clockify's free plan has no user limit and no project limit. The main restrictions are no invoicing, no approval workflow, and no project budgets. Many small agencies run on the free tier indefinitely and only upgrade when they need invoicing or timesheet approval.
Does Toggl Track integrate with GitHub?
Yes, Toggl has a browser extension that detects GitHub issues and pull requests, letting you start a timer directly from the GitHub interface. It also integrates with GitLab, Jira, Linear, and VS Code through the same extension mechanism.
Is Harvest worth the price compared to Toggl and Clockify?
For teams that invoice clients monthly on T&M billing, yes. The native invoicing + QuickBooks/Xero sync removes 1-3 hours of manual billing work per month per project. For fixed-fee projects where billing is less frequent, Harvest's advantage shrinks significantly — Clockify or Toggl would serve you equally well at lower cost.
