Professional services firms face constant pressure to accurately track time, bill efficiently, and manage multiple client projects without missing a beat. Manual time tracking leads to errors, billing cycles get delayed, and non-billable hours often go unaccounted for. Worse, many tools lack integration with essential project management software or accounting systems, such as QuickBooks, resulting in scattered data and making management time-consuming. Best time billing software can change that.
This guide examines the top time billing software for 2025, highlighting the leading tools to manage projects and explaining why BigTime is the preferred choice for professional services firms.
What Is Time Billing Software?
Time billing software enables businesses to track the time spent on projects, convert those hours into accurate invoices, and gain valuable insights into employee productivity and project health. It’s essential for firms that bill by the hour or require deep visibility into team capacity, billable time, and project progress.
Benefits include:
- Fewer manual entry errors
- Faster invoicing with automated workflows
- Real-time visibility into billable hours and non-billable hours
- Better team performance and project management
Key Features in Leading Time Billing Software Tools
When evaluating the best project management tool for time billing, these core features can make all the difference in streamlining workflows, improving accuracy, and maximizing billable hours.
Real-time Time and Expense Tracking
Accurate, on-the-go capture of time tracking data ensures that no billable hour is lost. Real-time expense capture enables teams to log costs promptly, reducing errors and enhancing financial transparency. This feature is essential for keeping projects on budget and clients informed.
Automated Invoicing
Turn tracked time into client-ready invoices without manual calculations. Automated invoicing tools streamline billing cycles, reducing delays and ensuring consistent cash flow. Custom templates and approval workflows also help maintain professionalism and compliance.
Budget and Project Tracking
Track project budgets against actuals in real time to ensure project profitability. These tools provide visual dashboards and alerts when projects exceed budget or fall behind schedule. They also help firms proactively allocate resources based on financial data.
Integrations with Accounting Tools
Seamless integrations eliminate duplicate data entry and synchronize financials across platforms like QuickBooks, Xero, and more. This connectivity ensures that billing, payroll, and expense data are aligned and up to date. It also enhances overall operational efficiency by linking time tracking with accounting.
Reporting and Analytics
Advanced reporting tools provide insights into time allocation, billable utilization, and team performance. Analytics dashboards can highlight trends, uncover inefficiencies, and support better decision-making. These reports are crucial for resource forecasting and strategic planning.
Mobile Access
Mobile functionality allows users to log time, submit expenses, and view project data from anywhere. This is especially valuable for remote teams or professionals who work on the go. Mobile access ensures teams stay productive and accountable, regardless of their location.
The Best Time Billing Software for 2025 Reviewed
To help you choose the right solution for your business, we’ve reviewed the top time billing software tools available in 2025, starting with BigTime, the industry leader.
BigTime
BigTime is an advanced time and billing software tailored for professional services firms. It offers comprehensive project management features, accurate time tracking, robust invoicing, and powerful analytics, all wrapped in a user-friendly interface designed for larger teams and growing firms.
Why BigTime Time Billing Software Stands Out
Purpose-built for Professional Services Firms
BigTime’s advanced features are specifically designed for industries such as consulting, engineering, architecture, and accounting. This focus means every feature aligns with the unique needs of project-based billing, resource planning, and client accountability. It eliminates the need for customization or workarounds found in more generic tools.
Deep Integration with QuickBooks, Sage Intacct, and Other Accounting Platforms
BigTime’s native, two-way integration capabilities ensure seamless data flow between time tracking and financial reporting. These connections reduce errors, eliminate duplicate entries, and save time on reconciliations. Users can trust that invoices, expenses, and budgets remain fully aligned.
Mobile App for Time and Expense Capture
With BigTime’s mobile app, employees can log hours, submit expenses, and track project updates anytime, anywhere. This flexibility enhances time capture accuracy, particularly for remote teams or professionals working in the field. It helps keep projects moving forward without administrative delays.
Real-time Budget Tracking
Monitor project budgets as they evolve, comparing actuals to forecasts in real time. This allows teams to make proactive adjustments and avoid overruns. The visibility helps maintain profitability and client trust.

Cost Rate vs. Bill Rate Management
BigTime enables firms to manage both internal cost rates and client-facing bill rates, allowing them to understand their true margins. This clarity supports more effective pricing strategies and ensures projects remain financially viable. It’s especially helpful for firms juggling multiple clients and contract types.
Expense Tracking
Easily capture, categorize, and assign expenses to specific projects or clients. This feature simplifies reimbursement, improves client transparency, and feeds directly into billing workflows. Teams can even attach receipts and add notes for better documentation.
Multiple Time Entry Options
BigTime’s time-tracking software supports manual entry, timers, and pre-filled timesheets to accommodate different workflows. Whether users prefer tracking by task, project, or day, the platform adapts to their habits. This increases adoption and ensures more complete data.
Project-based Time Tracking
Assign time entries to specific projects, tasks, or phases for detailed reporting and accountability. This makes it easy to analyze team capacity, client profitability, and project progress. It also supports better forecasting and workload planning.
Flexible Billing Models
Choose from hourly, fixed fee, retainer, or hybrid billing structures to suit different client needs. This flexibility enables firms to tailor their invoicing strategy according to the contract. It’s ideal for firms with diverse service offerings.
Configurable Invoicing and Approval Workflows
Set up custom invoice approval chains to match internal processes. Managers can review, edit, and approve invoices before they go to clients. This adds a layer of control and ensures consistency across the organization.
Custom Invoice Templates
Create branded, professional invoices tailored to different clients or services. Templates support itemized charges, custom fields, and dynamic formatting. This ensures each invoice reflects your brand while meeting client expectations.
Automated Invoice Generation
Turn approved time and expenses into invoices with a single click. Automation shortens the billing cycle and reduces manual work. Firms can spend less time on admin and more on high-value client work.
Custom Dashboards
Visualize KPIs, financial metrics, and project status with configurable dashboards. Users can build views tailored to roles, whether for project managers, executives, or finance teams. This supports data-driven decisions and promotes transparency.

Project Audit Trail
Maintain a full history of project updates, time entries, and billing changes. This is critical for compliance, dispute resolution, and internal accountability. Audit trails provide confidence for both the firm and its clients.
Exceptional Customer Support and Onboarding
BigTime’s support team helps firms get up and running fast, with guided setup, training, and ongoing assistance. Their proactive approach ensures users feel confident and supported from day one. Many firms cite this as a key reason they chose BigTime.
Role-based Access and Customization
Control who sees what by assigning roles and permissions tailored to each user. This enhances security, streamlines workflows, and keeps data clean. Customization ensures that each team member gets the right tools without distraction.
BigTime Is the Best Time Billing Software for Professional Services in 2025
BigTime stands out for its depth, flexibility, and scalability. With all the features you need, such as automatic time capture, real-time reporting, and team collaboration tools, it’s the complete solution for firms that want more from their project management tool.
Harvest
Harvest is a simple and accessible time tracking and invoicing tool designed for freelancers and small teams. Its clean interface makes it easy to log time and create invoices, but it lacks the depth needed for growing professional services firms.
Key Features of Harvest
Simple Time Tracking
Users can start and stop timers or enter time manually, making it easy to track work in real time or retroactively. The interface is clean and requires minimal training, helping teams get up and running quickly.
Expense Management

These integrations help sync tasks, projects, and financials, reducing double entry. The QuickBooks integration supports smooth billing workflows.
Summary
Harvest is ideal for independent consultants or small teams that require easy-to-use time tracking and invoicing. However, its limited customization, minimal reporting, and lack of advanced billing workflows make it a weaker fit for growing firms.

Cross-platform Access
Use Toggl Track on web, desktop, mobile, or via Chrome extension for flexible usage. This ensures you can capture time regardless of where you’re working.
Summary
Toggl Track is a great time tracking tool for individuals or teams that prioritize design and simplicity. However, it doesn’t offer invoicing, expense tracking, or project budgeting, making it unsuitable for firms that bill clients regularly or manage multiple contracts.

However, its cluttered user interface and steep learning curve can be a barrier, and it lacks the financial controls and other tools necessary for larger or more complex firms.
Clockify
Clockify is a freemium time tracking tool that provides unlimited users and projects at no cost. It’s a popular starting point for small teams looking to track time without budget constraints.
Key Features of Clockify
Unlimited Users and Time Tracking
There’s no cap on who can use Clockify or how much time you can track. This makes it ideal for growing teams or businesses just getting started.
Billable and Non-billable Tracking

Connect Clockify with apps like Trello, Jira, and Asana to embed time tracking into existing workflows. These integrations support efficiency but are fairly basic.
Summary
Clockify is great for startups or small firms that need to track time on a budget. But for firms with billing complexity or detailed project financials, Clockify’s capabilities fall short.

Hubstaff
Hubstaff combines time tracking with employee monitoring, making it well-suited for remote and field-based teams. Its monitoring-heavy approach may not align with all workplace cultures.
Key Features of Hubstaff
Screenshots and Activity Monitoring
Capture screenshots and measure keyboard and mouse activity to track employee focus. This supports accountability but can feel intrusive to teams.

Track worker location and movement, useful for field teams or mobile operations. Location-based time logging helps ensure accuracy for distributed teams.

Invoicing Tools
