Toggl Track and Harvest are two leading time-tracking tools used by freelancers, agencies and in-house teams across England and Europe. This comparison focuses on practical differences in time capture, reporting, invoicing, integrations, pricing and compliance in 2025–2026. It highlights migration steps, real pricing examples, and measurable benchmarks to choose the best fit for specific workflows.
Quick verdict and who should choose which
- Freelancers and simple billing: Toggl Track often wins for straightforward time capture, low friction timers, and flexible project tagging. It is strong where speed and ad‑hoc tracking matter.
- Agencies and invoicing-focused teams: Harvest excels at integrated invoicing and expense tracking linked directly to time entries. It tends to reduce invoice reconciliation workload.
- Scaling teams and integrations: Toggl Track offers a broader modern API and more lightweight desktop/mobile clients; Harvest offers deeper built-in billing features but fewer third-party syncs in some niche categories.
Decision tip: choose by the primary pain point — time capture velocity and report flexibility favor Toggl Track; native invoice workflows and project cost visibility favor Harvest.
Feature-by-feature comparison (2025–2026)
Time capture and user experience
- Toggl Track: intuitive one-click timers, robust manual time entry, idle detection improvements rolled out recently, and strong offline support on desktop and mobile with automatic sync. Best for teams valuing minimal friction when starting timers.
- Harvest: ergonomic timers plus built-in expense capture and quick invoice creation from time entries. Idle detection is present but historically less aggressive than Toggl; improvements released in late 2025 improved accuracy.
Reporting, analytics and export
- Toggl Track: offers powerful custom reports, export to CSV/XLSX, and visual weekly dashboards. Advanced filtering and project tags enable granular ROI analysis. API-first reporting supports automated exports.
- Harvest: reporting centers on project profitability and billable vs non-billable breakdowns. Exports focus on invoice-ready datasets. Harvest's reports are structured for client billing reconciliation.
Billing, invoicing and accounting
- Toggl Track: integrates with invoicing tools (e.g., Xero, QuickBooks) via connectors; no native full invoicing suite in standard tiers as of 2026.
- Harvest: native invoicing and expense tracking with built-in payment reminders and recurring invoices. Easier for teams that generate invoices directly from tracked time.
Integrations and ecosystem
- Toggl Track: broad ecosystem, major integrations with project management tools (e.g., Jira, Slack), and marketplace apps. API rate limits generous for most teams.
- Harvest: strong integrations with accounting and CRM tools; bidirectional sync options with fewer third-party plugins compared to Toggl. Built-in connectors for common bookkeeping stacks.
Mobile and desktop clients
- Toggl Track: lightweight native apps for macOS, Windows, Linux, iOS and Android; background tracking improvements in recent updates reduced battery usage.
- Harvest: solid native apps with tight invoice linking, but slightly heavier on resources for desktop clients.
Security, data residency and GDPR
Both platforms updated privacy policies for 2025–2026. Key differences:
- Data processing and transfers: Toggl Track stores data in EU/US regions depending on plan; Harvest provides region selection for business accounts in enterprise tiers. For UK/EU GDPR compliance, both publish Data Processing Addendums.
- Encryption: TLS in transit and AES-256 at rest claimed by both vendors.

Pricing, ROI calculator and worked examples (2025–2026)
Pricing overview (basic tiers as of Jan 2026)
- Toggl Track: Free tier with limited features. Paid tiers from approximately £8–£15 per user/month for Starter/Team plans; Enterprise custom pricing for SSO, dedicated support.
- Harvest: Free trial; paid tiers from approximately £10–£19 per user/month depending on invoice features and team controls.
Prices change frequently; check official pages: Toggl Track pricing, Harvest pricing.
Simple ROI calculator (example scenarios)
- Scenario A — Solo freelancer billing hourly: 20 billable hours/week, hourly rate £40, time saved 15 minutes/week on admin using one platform's automated invoices.
- Weekly earnings = 20 × £40 = £800. Admin time saved = 0.25 hours × £40 = £10/week ⇒ £520/year reclaimed.
-
If Harvest's integrated invoicing reduces reconciliation time by 1 hour/month (£40/month = £480/year), it justifies a higher per-user fee versus Toggl's lower subscription.
-
Scenario B — Small agency (5 people): each person bills 25 hours/week at average £60/hour. Consolidated reporting saves 2 hours/month for a project manager.
- Annual billable revenue = 5 × 25 × £60 × 48 weeks = £360,000. Small improvements in reporting (0.5% increase in billable capture) equal £1,800/year, often enough to justify subscription differences.
Recommendation: model the marginal time reclaimed (hours × blended rate) against annual subscription delta to decide. Use exports and sample reports to validate assumptions.
Migration guide — Harvest to Toggl Track (step-by-step with API tips)
Pre-migration checklist
- Export current Harvest data: time entries, projects, clients, invoices, expenses. Harvest export is available at getharvest.com.
- Map fields: client IDs → workspace, project names → projects, tags → tags, invoice numbers → external IDs.
- Identify required historical reporting windows and retention policy per GDPR.
Export from Harvest (CSV recommended)
- Navigate to Reports → Export in Harvest UI and export time entries and projects to CSV.
- Export invoices and expenses separately.
Import into Toggl Track via API (recommended for >1,000 entries)
- Create a new Toggl workspace via UI or API.
- Create clients and projects via Toggl API POST endpoints: Toggl API docs.
- Bulk import time entries using the Toggl API in batches (example curl):
curl -u api_token:api_token -X POST "https://api.track.toggl.com/api/v9/time_entries/bulk" /
-H "Content-Type: application/json" /
-d '{"time_entries": [{"start": "2025-12-01T09:00:00+00:00","duration":3600,"description":"Consulting","project_id":12345}]}'
- Validate imports by comparing totals with original Harvest CSVs.
Handling invoices and billing
- Harvest invoices should be exported for accounting continuity. If invoicing will be handled by an external tool (Xero/QuickBooks), import invoices into the accounting platform and link new Toggl projects by external IDs.
Post-migration validation
- Run side-by-side reports for a 2–4 week period to reconcile totals.
- Verify tax/expense records and check client invoices for any missing hours.
Note: For large migrations, consider professional services or using third-party migration tools. Toggl and Harvest APIs have rate limits; respect them and implement retries.
Integrations — level of compatibility (2026)
- Slack: Toggl Track (native app + slash commands), Harvest (notifications + timer integration).
- Jira: Toggl Track (extensions & dev tool integration), Harvest (time entries linked to issues via plugins).
- Xero/QuickBooks: Both support connectors; Harvest has invoice-friendly direct flows, Toggl uses third-party connectors for invoice creation.
A granular compatibility checklist should verify bi-directional sync, field mapping, and webhook availability.
Security, GDPR and data handling
- Both vendors publish DPAs and offer SSO options on business plans. Verify retention settings and right-to-be-forgotten procedures.
- Recommended: keep a documented data processing record and perform a DPIA if handling sensitive client data.
- Startup time: Toggl Track desktop clients start faster on average; Harvest desktop can take longer due to embedded invoice modules.
- Resource usage: recent Toggl updates improved CPU usage on macOS; Harvest remains stable but slightly heavier in memory.
- Sync latency: both platforms report near-real-time sync; observed delays can be network-related. For mission-critical offline capture, test mobile offline workflows.
Case study (quantified example)
- A 12-person UK agency migrated from Harvest to Toggl Track with external invoicing. Result: 6% increase in billable capture due to stricter tagging and 12 hours/month saved from automated exports — equivalent to ~£15,000 annual revenue uplift after migration costs.

FAQs (common user questions)
How to choose between Toggl Track and Harvest for a freelancer?
Freelancers prioritising speed and light UI often prefer Toggl Track for fast timers and tagging. Freelancers who need to turn tracked time directly into invoices with fewer tools prefer Harvest for built-in invoicing.
Can time entries be migrated without losing historical data?
Yes. Export full CSVs from Harvest and import via Toggl API in batches. Ensure field mapping and reconcile totals to avoid discrepancies.
Both vendors offer DPAs and encryption. Evaluate data residency, retention policies and contractual terms for UK-specific requirements. Consult the ICO for legal obligations.
Toggl Track generally starts faster and uses less CPU in typical use; Harvest provides more invoice-linked features at a slight resource cost. Benchmark on representative devices before large rollouts.
Will switching systems disrupt client billing?
Proper migration with invoice exports and side-by-side reconciliation for a transitional period prevents disruption. Retain historic invoices in accounting software and map new time entries to project IDs.
Conclusion
Choosing between Toggl Track vs Harvest depends on where value is realised: speed and flexible reporting or integrated invoicing and expense-linked time. For freelancers and teams needing rapid adoption and API-driven reporting, Toggl Track often provides a lower-friction path. For organisations where time-to-invoice and built-in billing accuracy matter, Harvest frequently drives immediate ROI.
The optimal approach involves running a short pilot, exporting existing data, modelling the cost delta against reclaimed administrative time, and using the migration checklist to validate outcomes. Security, GDPR compliance and integration compatibility should be part of vendor selection criteria in England and the EU.
